Besides three popular measures: K-means, Fuzzy and density, This study reveals homogeneous sub-regions over the poorly studied area of western equatorial Africa (10S–7N and 7E–30E). Since the flood occurred in the Malayalam Era 1099, it is known as the “Great Flood of ’99”. Results have shown that the regions identified by both analyses are largely same. The regions are geographically well distributed over the area In this analysis we found seven different climate zones in Bangladesh. Since the beginning of June 1, 2018, all the state’s districts received copious rainfall. The enrichment of the sediment in quartz grains coupled with the action of the current drift authorized the build-up of sandy spits and the genesis of the lagoon that preserve a rich assemblage of euryhaline ostracods and mollusks species. ous regions of Kerala under each cluster are identified. Key words. and compared: the rotated principal component analysis (RPCA) in conjunction with Ward's method, and the RPCA in conjunction Meteorologists say that the rainfall data over the last six years do not suggest a visible pattern. Annual rainfall data for 2009 to 2012 were obtained from Venkatesan et al. Flood frequency analyses for seven sub-groups defined by Ward's clustering method are carried out using various frequency distributions based on index flood and L-moments approaches. The accuracy of results of quantile estimates are evaluated by using relative RMSE% and relative BIAS% through the use of Monte Carlo simulation. Dealing with individual rainfall station is time consuming as well as prone to more variation. Rainfall in the four broad geographical Therefore, regionalization can be an essential tool to be applied for clustering the rainfall and spatial pattern analysis of homogeneous regions to quantify, Ward's hierarchical clustering method is applied to classify the annual floods and identify the hydrologic homogeneous regions in Turkey. The season/sub-region is also provided and compared. In 2013, all the state’s districts, except Thiruvananthapuram, received more than 1400 mm of rainfall. This transgression, also recognized in Sfax coast, revealed by the dominance of lagoonal ostracod associated to coastal and marine taxa, allows the settlement of an open lagoon. This year, even though Kerala has received 50% less rain than it did in 1924, the impact has been no less severe. Audio is not supported in your browser. Therefore, to minimize flood extremes, it is important to control the flood peaks at the upstream area through suitable watershed management practices. “The low pressure developed in the Bay of Bengal too contributed to the heavy rain fall.”, Pai said the only pattern scientists could establish is the low frequency and high intensity of rainfall. The document contains the vehicle population report of Kerala from 01/04/2015 to 31/03/2016. In this context, methodologies are used to estimate precipitation in unmonitored locations. The principal components that explain about 65% of total variance are retained and then varimax rotated. These algorithms are applied over precipitation data recorded by the Bangladesh Meteorology Department, and a comparison among the algorithms is made. In recent years, 2013 saw the highest rainfall that Kerala has received (2561.2mm). Kerala experiences rainfall for around 120 to140 rainy days per year. More than 20,000 homes have been completely destroyed and 10,000 km of roads have been damaged. The spatial pattern of seasonal precipitation seems to be highly controlled by the wide latitudinal extent of the region and by the pronounced orographic relieves, and the time of occurrence of the maximum precipitation varies from spring in the north to winter in the south. Monthly rainfall is calculated from these daily rainfall data using, MS Excel. April–May–June (AMJ), July–August–September (JAS), and October–November–December (OND). Moreover, the density of these stations network is not sufficient for estimation of rainfall at ungauged regions. Moreover, the performances of the proposed weighting approaches for spatial clustering analysis are better than no-weight scenario in most modes according to the spatial patterns and homogeneity measurements. It can also be concluded that extreme drought, which began in 2014, may be the beginning of another; the mega drought on the Korean peninsula based on the drought periodicity analysis. The stations are grouped based on the similarity of Find historical weather by searching for a city, zip code, or airport code. “The draught occurred because of El Nino,” said Dr D Sivananda Pai, Head of Climate Prediction Group at the India Meteorological Department in Pune. Oxygen isotopes values of Late Pleistocene are also 1.5‰ lower than modern precipitation. Get the most up to date statistical data selected state wise average rainfall, monthly rainfall, annual rainfall, daily rainfall in india growth details figures ... Factors Determining Morbidity in Kerala Foreign Trade Pattern of Nepal: Gravity Model Approach The disappearance of charophyte oogonia and planktonic foraminifera coupled with the enrichment of marine taxa marked the opening of our lagoon to the sea. Most months of the year are marked by significant rainfall. This study aimed to provide a historical mega drought information of Korea using the long-term precipitation for longer than 300 years that were observed by the Korean Meteorological Administration (KMA) during 1908–2015, and paleo-climate data by the Korea’s ancient rain gauge (Chuk-Woo-Kee) during 1777–1907 and future climate change scenario from 2017 to 2099. Monthly rainfall is averaged over the period of ava, initially begins with ‘n’ clusters each with one element. Malappuram (also Malapuram) (pronunciation) is a city in the Indian state of Kerala, spread over an area of 58.20 km 2 (22.47 sq mi). Data are inferred from archaeological sites of Punic-Roman age located between Ras Boutria (Jebeniena) and El Awebed (Sfax). Karnataka receives about 80% of the annual rainfall during the South-West monsoon period (June to September), 12% during the post-monsoon period (October to December), 7% during the summer season (March to May) and only 1% rainfall is received during the winter season (January to February). For sustainable accomplishment of, basins can be made available via regionalization. Monthly data from 34 climate stations for rainfall from 1991 to 2013 are used in the cluster analysis. Results show that the northern and southern regions of western Iran are characterized by different climatic variability. Until August 8, Kannur had received the maximum rainfall (2265mm). Three homogeneous regions of precipitation were identified, and the results of the performance indices from the regional models of probability distribution were satisfactory for estimating average monthly and annual precipitation. A T-mode Principal Component Analysis (PCA) based on a network including 68 pluviometric gauges and their 12 mean monthly amounts of rainfall is attempted in order to describe the main patterns governing precipitation in Spain. At 665mm, Thiruvananthapuram received the lowest. The clusters are also characterized to see how they are distributed. Identification of homogeneous regions and regional frequency analysis for Turkey. Hence for, nloaded from the site named, Global Weath, ming that, there are ‘n’ elements to cluster. division, Jalavijnan Bhavan, Thiruvananthapuram. However, in developing countries like Bangladesh, such hydrological information is rarely available at the watershed level. Two different algorithms are applied Los valores de concentración revelan una gradiente regional en dirección este-oeste, que va de moderadamente a fuertemente estacional. In the month of december, maximum temperature is 88°F and minimum temperature is 81°F (for an average temperature of 85°F). and regional homogeneity measures are applied to test homogeneity of regions identified by Ward's cluster method. The quantitative study of foraminiferal associations coupled with geochemical and sedimentological proxies, of a 94-cm sediment core from Korba lagoon (Cap Bon, Tunisia), enabled us to better understand the dynamics of depositional environments and identify different stages of evolution of the lagoon. Kannur received just 1852.5mm and only nine districts received more than 1000 mm of rain. Rainfall 2016-17 monsoon Rainfall (June – september) 1.7. Then numbers of classe, computed by using ‘pdist’ function in MAT, square matrix of size 63 × 63, to save space and c, tree from the distance, which is known as dendrogram. March is the hottest month in Kerala with an average temperature of 29°C (84°F) and the coldest is June at 27°C (81°F) with the most daily sunshine hours at 9 in February. Assuming the same number of clusters, the k-means method provides comparable spatial patterns with those of Ward's method. Furthermore, a negative long-term linear trend in the north and a weak positive trend in the south of the study area have been detected though they are not statistically significant. This study uses the annual maximum daily rainfall of 68 rain gauge stations. Clustering of Regional Precipitation here is about 3257 mm | 128.2 inch per year. Monsoon 2017 rains in Kerala : Latest news and update on Monsoon 2017 rains in Kerala In broad agreement with evidence from other paleoclimate investigations, the estimated noble gas recharge temperature (NGT) is lower than the present by about 5.5 °C. Kerala state is endowed with rich water resources like 44 rivers and two important, For the study, the main parameter required is the monthl, data of remaining 16 stations could not be received as they, these stations, Global Weather Data are used. and consist of roughly the same number of stations. Rain, The authors hereby acknowledge the financial suppo, College Trichur, Thrissur for seed money project “Var. Initially RMSSTD value d, Homogeneous regions of Kerala under each cluster are identified by ‘Thiessen Polygon Method’ an, Average annual rainfall of each cluster is calculated and tabulated in Table 3 and plotted in Fig. This study investigates the clustering methods in terms of the similarity, members and homogeneity, among the clusters formed. On average, June is the wettest month. merged clusters as a function of the stage analysis. Mexico; 2007. (212) 419-8286 It is found that the region can be grouped into seven clusters. Include a date for which you would like to see weather history. Join ResearchGate to find the people and research you need to help your work. RMSSTD value is calculated at each st, and RMSSTD is given in Fig.8. Later, considering the heterogeneity in the hydroclimatic and topographic details, entire rain gauge stations have been clustered into six hydroclimatically homogeneous regions; namely, northeast (NE), northwest (NW), southeast (SE), southwest (SW), coastal, and central regions, by using the k-mean clustering technique. Such groups can be identified using clustering algorithms, techniques used in the multivariate data analysis. Therefore, in the present paper, an attempt has been made to derive the regional best fit extreme rainfall pattern for Bangladesh for the estimation of extreme rainfall quantiles. In 2013, all the state’s districts, except Thiruvananthapuram, received more than 1400 mm of Kannur, with 3119.4 mm, got the most rain. These parameters marked the settlement of a closed lagoon separated from the open ocean by a sandy bar with high foraminiferal productivity in fine sediments. Monthly totals of 141 stations covering the period 1955–1984 are used. All data correspond to the average monthly values of the last 20 years. But with the south-west monsoon likely continue until the end of September, this year’s figure may breach the 2013 level. Kochi Temperature Yesterday. This question is for testing whether you are a human visitor and to prevent automated spam submission. On average, January is the driest month. More than 30,000 people have moved to government relief camps, Vijayan said. The statistical analysis results showed that annual average precipitation were considerably different between records by the Chuk-Woo-Kee and records by the KMA. September, 2016 was 3% lower than Long Period Average (LPA). ... Regionalization is a possible technique that can provide hydrological data at low cost. Ildiko Pelczer, Judith Ramos, Ramón Domínguez, Fernando González. Thus, the objectives of this work are to i) identify homogeneous regions of precipitation in the Tocantins-Araguaia Hydrographic Region (TAHR) via the fuzzy c-means method, ii) regionalize and estimate the probability of occurrence of monthly and annual average precipitation using probability distribution models, and iii) regionalize and estimate the precipitation height using multiple regression models. For which a statistical fact. Location of Raingauge Stations in the Watersheds of Kerala, Cluster Map of Kerala based on Ward's Method, International Conference on Emerging Trends in, Regionalization of Rainfall in Kerala State, place objects into groups suggested by the data, so, Peer-review under responsibility of the organizing committee of ICETEST – 2015, Ghats located on the eastern boundary of th, to manage the optimum use of available water resour, hence the technique of regionalization ga, clusters are required according to the type of data or ob, these questions, hierarchical and non-hierarchical algorithms, for precipitation and temperature available from traditional weather statio. The two regional distributions obtained not only correspond fairly well to the large, well-known physical regions of Switzerland, but also go much further, separating the Swiss Plateau into 3 clearly differentiated regions, for example. After analysing the data for 115 years from 1901 to 2016, scientists have also established a decrease in southwest monsoon rain. Este estudio presenta un análisis espacial y temporal de la agresividad climática en la cuenca del río Guayas ubicada en la costa y Andes ecuatoriales. regional rainfall patterns. The clustering process was conducted temporally and spatially using the Ward’s linkage method of Agglomerative Hierarchical Clustering (AHC). Climate data for cities worldwide Select a continent Africa; North America; South America; Asia; Europe; Oceania; Popular places. This is visible across India.”. To perform Ward’s hierarchical, number of clusters is decided by noting the RMSSTD. For regional frequency analysis, the L-moment method was applied. Clustering is the process of dividing the area under consideration to a limited number of climatologically homogeneous zones, based on any hydrologic parameter. Open data provides access to data generated by various departments of Government of Kerala within the framework of various policies, acts and rules of the government. Five Agglomerative Hierarchical clustering measures based on mostly used six proximity measures are chosen to perform the regionalization. Los resultados indicaron dos regiones homogeneas predominantes, la primera ubicada al oeste en la zona costera y andina (85.2% del área de la Cuenca), con un índice de agresividad alto y muy alto, mientras que la distribución de la precipitación en la segunda región (Alta montaña) resultó de muy baja a baja agresividad. Seven regions were highlighted in the first case and 13 in the second. In the Year 2016, the cumulative monsoon rainfall for the country as a whole during 1. st. June to 30. th. The clustering results showed that based on the different attributes categories, different results can be presented in terms of the number of clusters, distribution of stations, and spatial pattern of clusters. AMJ, JAS and OND and 4 sub-regions for JFM and annual data. Three districts were in Excess rainfall category: Palakkad (2125.9 mm, 39% above normal), Thiruvananthapuram (1039.9 mm, 20%, the lowest rainfall district of Kerala) and Kozikod (3466.6 mm, 34%, the highest rainfall district of Kerala). © 2008-2021 ResearchGate GmbH. El análisis de tendencias de la concentración de lluvia mensual no muestra cambios significativos en el periodo de estudio. analysis. The first revealed high abundance of foraminifera dominated by lagoonal taxa associated with high TOC, TIC and Ca contents. based clustering techniques are applied initially to decide the most suitable method for the identification of homogeneous region. According to the Indian Meteorological Department data, Kerala received 1739.4 mm of rain from June 1 to August 8. In addition to annual totals, four different seasons are examined separately for regionalization, ces round the year. Climate in Kerala in december Climate in Thiruvananthapuram in december. Consequently, the aim of this study is to select a broad category of climatic, geographical, and statistical attributes of the maximum 24-h rainfall of the Urmia Lake Basin for 63 selected stations for the period 1979–2008 and next to determine an appropriate weight for each of the attributes in each defined category. Kannur district topped the charts with 2537.4 mm. RMSSTD is represented mathematically as given in “(1)”. Of Visitors : 8779745: Developed By: The procedure is applied to a 12 12 intermonth covariance matrix; the unrotated components and two additional solutions deduced after varimax and oblimin rotations are presented and discussed. Ten districts got rainfall between 1055 mm to 1854 mm, while three districts received below 1000 mm. On an average, there is one raingauge station for every 3886.4 sq.km area. Two regionalizations of Spanish rainfall are then obtained and compared in terms of group homogeneity. The excess rainfall since the onset of monsoon in Kerala on June 1 has claimed 23 lives and damaged properties worth crores of rupees in 374 … In this study, groundwater residence time and recharge conditions of the deep aquifer of Sfax were investigated using environmental isotopes and noble gases. Thiruvananthapuram received just 889 mm. There follows a discussion concerning the main pluviometric characteristics of each region deduced from the best division. A month after the onset of the Southwest monsoon in Kerala, official figures said the state received normal rains with four of the six northern districts recording an excess in rainfall. Se seleccionó datos mensuales registrados de 30 estaciones pluviométricas para el periodo de 1968-2014. Since Friday, 47 have died in the disaster and four have gone missing so far. The time variability of dry and wet periods in the identified sub-regions was analyzed using the Precipitation Index (PI) and the existence of any long-term trend was tested. Using the derived distributions, regional extreme rainfall quantiles were estimated, followed by geo-mapping in ArcGIS 9.2. In all cases component scores are computed and their spatial distribution is discussed. “Any shortfall in one season is compensated by other season so that annual water stress is minimised during most of the years.”. Back to overview: India The actual rainfall received in Kerala during the South-West monsoon (June 1 to September 30, 2016) was 1352.3 mm as against the normal rainfall of 2039.7 mm in 2016 showing (-)34 percent departure from the normal, which was the highest in the country. Using the hierarchical technique of clustering Ward's method, three clusters have been obtained in winter and spring, and four clusters have been obtained in summer and autumn. Expected rainfall from 1stJune to 30stSeptember, 2016 for Kerala was 2039.6 mm while actual rainfall was only 1352.2 mm with -34% departure. Stability of the cluster is also tested based on nine validity indices. The short dry season has little impact. “This means rainfall happens for a short duration but the amount of precipitation will be higher,” he said. Climate zones of Bangladesh are identified by using mathematical methodology of cluster analysis. Furthermore, nine precipitation-derived parameters were used to regionalize climate in western Iran using principal component analysis and clustering techniques. Homogeneous regions are usually defined based on different methods and with consideration of a category of attributes. Under such circumstances, it is important to use a hydrological model representing the rainfall-runoff process to arrive at the extreme flows in the rivers, which require extreme rainfall data as a major inflow to the hydrologic system. rt from TEQIP Phase II, Government Engineering, Baeriswyl P. A., Rebetez M. Regionalization of Pr, Fernandez Mills G. Principal Component Anal, Md. Moreover, in terms of cluster homogeneity, Fuzzy C-means algorithm outperforms the other clustering methods. Kerala received the highest rainfall in its recorded history – 3368mm – during the 1924 south-west monsoon. 6. Eight other districts received more than 2000 mm. an approach that, The lack of data in rainfall stations of Iran is one of the main problems in design and management of hydrologic systems. in 2016, 2017 and 2018. Clustering of Regional, Raziei T., Bordi I., Pereira L. S. A Precipitation based region. Discordancy. The average annual temperature is 27.5 °C | 81.5 °F in Pala. Annual and seasonal precipitations from 1977 to 2012 recorded in 30 stations are used in this study. With 1.9in over 8 days, you will experience some showers during your holidays. Kerala receives copious rain (average 3000 mm a year)each year. Initial estimates put monsoon-related losses at Rs 8,316 crore, he said. A research paper that analysed the inter-annual variability and trend of the changing characteristics of droughts over Kerala has found that the annual and summer monsoon rainfall over Kerala is showing a decreasing trend and post-monsoon rainfall is found to be increasing. similar clusters are being merged early in the process, these distances are small, and they increase relatively little by, little as the clustering proceeds. It seems reasonable and advantageous to deal with a group of homogeneous stations rather than an individual station. Meteorologists say that the rainfall data over the last six years do not suggest a visible pattern. The average amount of annual precipitation is: 999.9 mm (39.37 in) Vehicle Population in Kerala 2015-2016. Seven districts got more than 2000mm, six districts got between 1100 mm and 1800 mm while Thiruvananthapuram got the least amount of rain at 719.7 mm. A determinação dessas regiões homogêneas de precipitação é uma importante contribuição para o entendimento do comportamento climático na bacia hidrográfica, podendo auxiliar na gestão dos recursos hídricos. The comparison of both methods indicates that cluster analysis is suitable to establish spatio-temporal patterns of seasonal rainfall distribution in Spain.

The technique of principal component analysis and of cluster analysis has been applied to two sets of precipitation data in Switzerland, one containing 47 stations (1961–80), and the other 101 stations (1981–1993), with the aim of understanding more fully the spatial distribution of precipitation regimes. The same is done by Ward's Clustering method by taking the monthly rainfall data for five consecutive years from 2008-2012 of 63 raingauge stations in Kerala state. This process was probably responsible of the obstruction of the historic Boutria harbor and the abandon of the historic city. The study revealed three groups of months which are, rainy months group (December–March), moderately rainfall months group (April–November) and dry rainfall months group (May–October). ... After analysing the data for 115 years from 1901 to 2016… Regional distributions such as those discussed here can have value for climate change issues, and in particular numerical modeling of climate or climate change impacts on forests. The first and the second clusters include the northern part of Jordan characterized by high rainfall intensity, whereas the third group includes the southern part of Jordan and the last cluster represents the Badia and desert of Jordan country. All rights reserved. The four 3-month seasons are defined as follows: January–February–March (JFM), To investigate the weighting effect in regionalizing and to determine the appropriate weight for each defined attribute, respectively, Ward's clustering technique, principal component analysis, and correlation coefficients matrix methods were used. New data evaluating the relative sea level changes and sedimentary dynamics along the coast of Tunisia are presented. Definiram-se 3 regiões homogêneas de precipitação, as quais foram validadas pelo índice de Silhouette. The progressive modification of foraminiferal association revealed by the increase of lagoonal species and the decrease of estuarine taxa prove the settlement of the present-day lagoon conditions. Considering this, it is important to develop regional extreme rainfall maps for the reliable estimation of flood flows in the river by using a suitable modeling approach. The purpose of cluster analysis is to place objects into groups suggested by the data, so that objects in a given cluster tend to be similar to each other and objects in different clusters tend to be dissimilar. The results show that all sub-regions are strongly homogeneous.
