From Thorn HC, the maximum likelihood solutions are used to optimally estimate α and β: n = number of precipitation observations. Three distinct seasons can be recognized from climatic point of view: the dry winter season Rabi (November to February), the pre-monsoon hot summer season Pre-Kharif (March to May), and the rainy monsoons season Kharif (June to October) [6]. In the same year, Northern region, most of the central region and some area of eastern region were affected by extreme and severe drought conditions. Weather Clim Extremes 1: 42–50, Spatio-temporal analysis of meteorological drought variability in the Indian region using standardized precipitation index. In addition, four years moderate drought was prevailed in Barisal, Khulna and Satkhira during rabi seasons (Table 2). ABSTRACT Spatial distribution of categorical monsoon rainfall used in Bangladesh Meteorological Department (BMD) over Bangladesh during 1985-2014 using daily rainfall is accomplished in this study. During Kharif season the highest oneyear extreme drought in Comilla, Dhaka and Madaripur; severe three year’s drought in Faridpur and Mymensingh; moderate five years drought was occured in Comilla. The Bangladesh Meteorological department is acknowledged for providing observational data. According to the data of Kharif season, two years extreme drought in Khulna, two years severe drought was in Bhola, Jessore, Khepupara, Maijdi Court and Patuakhali. The cumulative probability, H(x), is then transformed to the standard normal random variable Z with mean zero and variance of one, which is the value of the SPI. Cambridge University Press, Cambridge, England, UK. And the percentage of dry period was 60% in Chandpur and 55.56% in Madaripur and Mymensingh (Table 2). Bangladesh is a more vulnerable to climate change due to its geographical condition. DEPARTMENT OF METEOROLOGY AND HYDROLOGY (MYANMAR). In Kharif season, only northern region showed increasing trends with a rate of 2.63% per 10 years and the other three regions namely central region, eastern region and southern and western region were found decreasing trend 1.05%, 3.02% and 3.02% per 10 years respectively (Figure 3). It is mainly focused on the development of models for long term rainfall prediction of Bangladesh divisions and districts (Weather Stations). Climatic Change 105: 433–453, Agricultural vulnerability and poverty alleviation in Bangladesh. SPI values of 35 meteorological stations have been determined then with these SPI value point shape file prepared by ArcGIS10 software. It was the heaviest rainfall in Islamabad in the past 100 years. The significant drought events were found in 1992, 2008, 2012 and 2014 in Pre-Kharif, 1981, 1985, 1992, 1994, 2006 and 2012 in Kharif and 1985, 1986, 2005, 2006, 2009, 2010 and 2012 in Rabi season. Figures 1-3 presented the changes and linear trends of drought areas (SPEI ≤ 1) from 1980 to 2015 over three cropping seasons (Pre- Kharif, Kharif and Rabi) of different regions of Bangladesh. The SPI value for Pre-Kharif, Kharif and Rabi seasons have been analyzed through geo-spatial analysis using GIS. So, agricultural planners and irrigation engineers should take necessary steps to mitigate drought vulnerability based on agro-climatic conditions of Bangladesh. The most significant increasing trend of drought was found in Rabi season with a rate of 8.66% per 10 years and Pre-Kharif season with a rate of 2.57% per 10 years. Spatial analysis (surface interpolation by ordinary krigging) with these point data were done by the ArcGIS10. Preprints, 9th Conference on Applied Climatology, 15-20 January, American Meteorological Society, Dallas, Texas. This page includes a chart with historical data for Bangladesh Average Precipitation. Among these 34 stations, only two stations, Sylhet and Srimangal, observe rainfall in the northeastern zone which lies in the Meghna basin. The base data for this work has been collected from Bangladesh Meteorological Department. Rainfall. Rainfall : 0 mm; Wind : 5 kph . Study areas are located in a tropical monsoon climate characterized by marked seasonal variations. Extreme, severe and moderate drought events were found about 68% of the total area of Bangladesh in 1994. The resulting parameters are then used to find the cumulative probability of an observed precipitation event for the given month and time scale for the station in question. Flood; Geological Disaster. During Kharif season, T. Aman rice is tremendously affected by drought whereas in Rabi and pre-kharif season; wheat, potato, mustard and T. Aus rice are mainly affected. 3. The highest rainfall of 620 millimetres (24 in) was recorded in Islamabad during 24 hours on 23 July 2001. List of Scientist; List of Engineers; AWS Data; WB Project. Monthly precipitation data of 35 meteorological stations were taken from Bangladesh Meteorological Department for a maximum period of 36 years from 1980 to 2015. Computation of the SPI involves fitting a gamma probability density function to a given frequency distribution of precipitation totals for a station. Among others, the Colorado Climate Center, the Western Regional Climate Center, and the National Drought Mitigation Center use the SPI to monitor current states of drought in the United States. The temporal and spatial variation of meteorological drought in the study area has been identified using SPI in multiple time scales. Theor Appl Climatol 119: 679–688, Some methods of climatological analysis. Where, Kharif season represented decreasing trend with a rate of 2.47% per 10 years. Again, from the spatial variation of meteorological drought in Kharif season (Figure 7), it is seen that the severe and moderate drought events were occurred in few parts of northern region, south-western region, central region and eastern region in 1981, which was 31% of total area. (2018) Identification of Meteorological Drought Prone Area in Bangladesh using Standardized Precipitation Index. Drought Mitigation Center Faculty Publications p: 17, Analysis on aridification within last 50 years in China. From these three seasons the highest percentage of dry period was found in Pre-Kharif season. Descriptive statistics of number of drought years, percentage of dry and wet periods of Pre-Kharif, Kharif and Rabi seasons of the study periods has been presented in the Table 2. Bangladesh BMD monthly rainfall: Bangladesh Meteorological Department. Also, some researchers [18-21] used the SPI and other indexes to evaluate the spatial and temporal drought characteristics in various regions across the world. Meteorological drought; Rainfall data; Spatial analysis; SPI"> The highest frequencies of dry period were 60.00% in Syedpur and 44.44% in Rangpur.

On the other hand, the north-western region was the most vulnerable region of the country [4] which experienced most severe drought because of high variability in rainfall [5]. Major finding of this study was Pre-Kharif and Rabi season were the most vulnerable to meteorological drought that indicates high seasonal rainfall anomaly in most of the regions of Bangladesh. The most significant increasing trend of drought area was found in Rabi season and decreasing trend was found in Kharif season. Among the many abiotic stresses drought was more prominent in northern and south-western regions of Bangladesh compared to the other parts of the country [3]. Monthly precipitation data of 35 meteorological stations were taken from Bangladesh Meteorological Department for a maximum period of 36 years from 1980 to 2015. Copyright: © 2018 Al-Mamun A, et al. On the other hand, two extreme droughts in Rajshahi, three severe droughts in Dinajpur, fifteen normal droughts in Bogra and five moderate droughts in Bogra and Ishurdi were prevailed during Kharif season.

For monitoring drought, there are various indices that measure how much precipitation for a given period of time has deviated from historically established norms. Drought is nothing but a natural disaster which prevails due to scarcity of water or moisture. In 2012, eastern regions were severely affected, and some area of central region and south-western region were moderately affected by meteorological drought. The record breaking rain fell in just 10 hours. Analyses have been done for two annual maximum data series. On the ther hand, Feni and Teknaf stations were found highest two years of extreme drought in Kharif season where Feni was also faced three years severe droughts; Kutubdia and Rangamati were faced four years moderate droughts and Teknaf faced sixteen years normal droughts. Water Resources and Hydropower Engineering 41: 78-82, [From(publication date): 0-2018 - Dec 12, 2020]. In this study, different features of meteorological drought including frequency of drought, dry and wet periods, percentage of drought area, temporal and spatial variations of drought in Bangladesh were examined. The Köppen-Geiger climate classification is Aw. Among the all regions of Bangladesh, significant drought years of Kharif seasons were 1981, 1985, 1992, 1994, 2006 and 2012. Widespread and large droughts occurred in Pre-Kharif season in the years of 1992, 1995, 2007, 2008, 2012 and 2014 over the different regions of Bangladesh.
