6 miles and an atmospheric pressure of 1014 mb. Daily maximum temperature and normal daily rainfall data were collected for north-western region of Bangladesh for the period 1981-2008. The daily rainfall data of Rangpur, Dinajpur and Sylhet stations were collected for the years 2004 and 2006 from either source and used in this study. The northwestern part of the country, drought is a common phenomenon and became a growing concern in the recent years. However, during the monsoon, extensive rainfall increases the incidence of devastating natural disasters (e.g., floods). 2018, Article ID 1849050, 18 pages, 2018. https://doi.org/10.1155/2018/1849050, 1Department of Geography and Environment, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh, 2Department of Geography, College of Social Science, Kongju National University, Singwan-Dong, Gongju-si, Chungnam-do 32588, Republic of Korea. Therefore this indicates that the irregularities of Rainfall during Winter Season are high (Figure 11). The most irregular and strongly irregular distributions were observed in the OND period, which was influenced by winter weather. The PCI calculated on a seasonal scale varied across the study area, from values of less than 10 to more than 20. Bangladesh. In this study, the rainfall data from 30 meteorological observatory stations across Bangladesh were collected for the period 1980 to 2011. In this study, the rainfall data from 30 meteorological observatory stations across Bangladesh were collected for the period 1980 to 2011. ... API - Real-time data stream to power next-generation apps. The central (excluding Dhaka) and west areas also showed comparatively higher values, while low but irregularly distributed values were observed in the central to north–east regions (Figure 3(b)). OCHA coordinates the global emergency response to save lives and protect people in humanitarian crises. 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. For this reason, APHRODITE precipitation products have the potentiality to be used as a key decisive source of rainfall information for the evaluation of satellite rainfall estimates over Bangladesh. During the JJ period, the PCI continued to show moderate-to-high irregularities. For the seasonal and three-month analyses, the values were generally moderately irregular. A negative trend of PCI means concentration of rainfall during monsoon in some parts of Bangladesh is increasing. (a) Annual; (b, c) supraseasonal (b = JJ, c = JD); (d–f) seasonal (d = NDJF, e = MAMJ, f = JASO); (g–j) three months (g = JFM, h = AMJ, i = JAS, j = OND). For all regions, the annual PCI values were moderate and irregular, and the six-month (JJ and JD) PCI values were irregular to moderate. In this study, the rainfall data from 30 meteorological observatory stations across Bangladesh were collected for the period 1980 to 2011. The lowest PCI values during the JAS period were less than 10 (Figure 3(i)) and were characterized by uniform precipitation concentrations across the study area.

The observed rainfall data were available from two sources BMD and BWDB. Only in a few humid months per year the intense of rain is a bit higher. The monsoon season (JASO), when precipitation was generally more uniformly distributed, had lower PCI values (Figures 5(g)–5(i)). During the SO period, some anomalies were found in the northwestern, central, and southeastern areas (Figure 4(i)). Bangladesh experiences a monsoon climate and has a flood-plain topography, making it prone to hydrological disasters. A moderate precipitation distribution was most common in the premonsoon season, although the north–west and south–east areas showed comparatively higher values (>12) than the west, central, and northeast areas (Figure 3(e)). PCI is an indicator of rainfall concentration and rainfall erosivity [28]. Precipitation in Bangladesh averaged 202.39 mm from 1901 until 2015, reaching an all time high of 1005.33 mm in September of 1934 and a record low of 0.01 mm in December of 1993. Dhaka Temperature Yesterday. 08 Jul 2018. The distribution of the annual PCI varied from <14 in the north–east (along Sylhet, Srimangal) to >18 in the north and south–east (Figure 3(a)) near the Bay of Bengal, where a moderate-to-irregular precipitation distribution was observed. The results showed that precipitation is the most uniform during the monsoon season. The climate is tropical in Dhaka. Dhaka Temperature Yesterday. Precipitation conveyance and measurement can provide a better understanding of the exact mechanisms driving these phenomena for disaster prediction and water management [12]. The climate in Bangladesh The climate in Bangladesh is subtropical. The OND period showed the strongest irregularities in precipitation distribution during 2000–2011 (Figure 6). BD, Bangladesh; NNWR, north-northwest region; CR, central region; ESER, east-southeast region; SSWR, south-southwest region. Rainfall prediction is very important for the Bangladesh … JFM had moderate and irregular distributions during 1980–1989 and 1990–1999 but irregular and strongly irregular values during 2000–2011 (Figures 6(a)–6(c)). In this study, precipitation concentration changes at different temporal intervals were compared for the four regions of Bangladesh. Subjects admitted to the adult … Temperature in Bangladesh decreased to 18.44 celsius in December from 23.08 celsius in November of 2015. Finally, we analyzed the annual, supraseasonal, seasonal, and three- and two-month PCI values using the Kruskal–Wallis test to identify statistical significance among the decades. We are committed to sharing findings related to COVID-19 as quickly as possible. Xu, and Z.

Moreover, the periods of JFM and OND showed strong irregularities in the PCI values corresponding to the dry season [39]. PCI can help quantifying the relative distribution of the rainfall patterns [28]. Rainfall : 0 mm; Wind : 9 kph . The PCI on a supraseasonal scale demonstrated a complex precipitation distribution across the study area. Bangladesh is a low-lying river-dominated country consisting primarily of flat plains. Release Date: 2018-05-10. The daily rainfall data of Rangpur, Dinajpur and Sylhet stations were collected for the years 2004 and 2006 from either source and used in this study. The purpose of this study was to analyze precipitation concentration rates in different regions of Bangladesh using the precipitation concentration index (PCI) and the inverse distance weighting method. The results showed that the rainfall in Bangladesh is moderately seasonal, with an intensity increasing from the premonsoon to the monsoon season, driven by weak tropical depressions from the Bay of Bengal. Data. Two-month PCI changes in different periods from long-term mean PCI (1980–2011) (series 1 = 1980–1989, series 2 = 1990–1999, and series 3 = 2000–2011). The PCI was calculated for annual, supraseasonal, seasonal, and three- and two-month data over a period of 30 years (1980–2011). The decadal analysis (1980–1989, 1990–1999, and 2000–2011) showed that the annual PCI values have varied over time and exhibited irregular distributions. It will be dry with no precipitation and cloud covering 11% … The data was provided as the daily total rainfall in millimetres. The annual PCI values were moderate with some irregularities (Figure 2). The analysis showed that rainfall concentrations were most heterogeneous in nonrainfall seasons (JF, FM, MA, AM, ON, and ND) and in the transition period before and after the monsoon. At all scales, a PCI value of 16–20 indicates that the total precipitation is concentrated in half of the period, and a PCI value greater than 20 indicates that the total precipitation is concentrated in one-third of the period. Climate change due to global worming is a major concerning issue in the world. Md. Daily Rainfall Data; License .

Precipitation is changing on global and regional scales by the influence of warming [1–4]. Learn more about ReliefWeb, leading online source for reliable and timely humanitarian information on global crises and disasters since 1996. On average, December is the driest month. This observational study examined the association of temperature, humidity and rainfall with six common climate-sensitive infectious diseases in adults (malaria, diarrheal disease, enteric fever, encephalitis, pneumonia and bacterial meningitis) in northeastern Bangladesh. Six-month PCI of JJ for (d) 1980–1989; (e) 1990–1990; (f) 2000–2011. Precipitation concentration changes were lower from 2000 to 2011 than in the earlier decades. A moderately irregular distribution was observed when the four regions shared similar climatic conditions. Climate 2018, 6, 9 3 of 16 Time series of rainfall records were collected from the Bangladesh Meteorological Department (BMD) for 35 different locations all over the country (Figure1). It occupies an area of 147,570 km2 and geographically extends from 20°34′ N to 26°38′ N and from 88°01′ E to 92°41′ E. Most of the population lives in rural areas and directly or indirectly depends on agricultural activities. The amount and intensity of precipitation can influence soil erosion, slope instability, plant growth, and agricultural practices [8, 9] as well as modify fluvial systems, groundwater recharge, water disposal, and hydroelectric projects [10, 11]. Six-month PCI of JD for (g) 980–1989; (h) 1990–1990; (i) 2000–2011. This enabled decadal comparisons (1980–1989, 1990–1999, and 2000–2011) between four regions, covering the whole study area. Significant changes in the PCI values between 1980 and 1989 and between 1990 and 1999 were found for the extreme northwestern and southeastern regions. During the AMJ period, which generally exhibited a moderate distribution, only the north–east region showed a uniform distribution (Figures 6(d)–6(f)). According to the analysis of the PCI formulae, on annual, seasonal, and supraseasonal scales, a PCI value of less than 10 indicates perfect uniformity of precipitation distribution (i.e., the same or highly similar amounts of rainfall in each month). Maximum temperature yesterday: 78 °F (at 3:00 pm) Minimum temperature yesterday: 65 °F (at 6:00 am) Average temperature yesterday: 71 °F This page includes a chart with historical data for Bangladesh Average Precipitation. This page includes a chart with historical data for Bangladesh Average Precipitation. DHAKA, September 26, 2018 — Nearly half of South Asia’s population, including more than three-quarters of Bangladesh’s population, is at risk of declining living standards due to rising temperature and erratic rainfall from climate change, says a new World Bank Report.. The IPCC–2007 report found a precipitation increase from 1900 to 2005 north of latitude of 30° [13], and Bangladesh, which is one of the most flood-prone areas of the world, was highlighted as one of the most vulnerable countries [14]. The data used to support the findings of this study are available from the corresponding author upon request. The observed rainfall data were available from two sources BMD and BWDB. The two month PCI values showed that precipitation variation mostly occurred during seasonal transition periods. For the spatial analysis of precipitation, we interpolated data from all weather stations onto a regular grid. International Journal of Integrated Sciences & Technology 3 (2018) 16-23 Study of a Heavy Rainfall Event in Bangladesh Using Global Satellite Mapping of Precipitation Data J. Hossain*, A. T. M. S.

Depending on the season, the average daytime temperatures range between 25 … Temperature has a significant influence on rainfall; during summer, temperatures can reach 45°C or greater, and in winter, they can fall to 5°C in some areas [21]. Depending on the season, the average daytime temperatures range between 25 … Bangladesh Rainfall and River Situation Summary as on July 13, 2018 Format News and Press Release Source. For the case of dynamic combination, generally Bangladesh faced extreme floods and longer periods of droughts [5, 16, 17]. The climate in Bangladesh The climate in Bangladesh is subtropical. Short-term variations also increased during the decade 2000–2011, during which the OND period saw the most irregular precipitation distribution. Data and Resources. Design/methodology/approach – The model generated rainfall was calibrated with ground-based observed data in Bangladesh during the period of 1979-2006. But the rainfall data was available for the period 1981-2005. List of organizations that are actively providing ReliefWeb with content. This analysis uses 30 years of data from 1984–2013. Several studies in the world indicate that global warming has strong influence on precipitation variation as well as extreme weather events like floods, droughts, and thunderstorms [18, 19, 20]. For the supraseasonal analysis, significant differentiation was observed during 1990–1999 for the JJ period and during 2000–2011 for JD period (Figures 7 and 8). For example, this last value indicates that most annual precipitation occurs within four months, most supraseasonal precipitation occurs within two months, and most seasonal precipitation occurs within one month. List of alerts, ongoing and past disasters covered by ReliefWeb. In facing the climate change impact, the country has made solid progress. For most decades, the three month PCI values showed variations in precipitation concentration, with the exception of JFM and JAS during 1990–1999 and 1980–1989. First, we performed a comparative correlation between the PCI values for the two- and three-month temporal intervals to understand specific variations. During Winter Season (November–February) a positive trend of PCI values are evident. Decadal analysis of annual PCI for (a) 1980–1989; (b) 1990–1990; (c) = 2000–2011. Decadal analysis of the three-month PCI for JFM during (a) 1980–1989, (b) 1990–1990, and (c) 2000–2011; AMJ during (d) 1980–1989, (e) 1990–1990, and (f) 2000–2011; JAS during (g) 1980–1989, (h) 1990–1990, and (i) 2000–2011; OND during (j) 1980–1989, (k) 1990–1990, and (l) 2000–2011. The result showed that significant changes in the precipitation occurred during the period of 1980–2011. Bangladesh Today; Bangladesh 24hr Forecast; Bangladesh 48hr Forecast; Bangladesh 72hr Forecast; Bangladesh 96hr Forecast; Bangladesh 120hr Forecast; Reports. Precipitation concentration is an important component of climate, and an unbalanced distribution of precipitation can yield excess or scarcity of water resources, which in turn can influence plant growth, flood risk, and water resource use. Rainfall variability in space and time is one of the most relevant characteristics of the climate of Bangladesh where hydrological disaster is a common phenomenon [5]. Curated pages dedicated to humanitarian themes and specific humanitarian crises. The Climate Research Unit (CRU) data are also used for understanding of the model performance. On average, August is the wettest month. A sub-tropical monsoon climate is strongly active, and the country is sometimes affected by tropical cyclones [32]. validation the MRI-AGCM was adapted for Bangladesh for generating rainfall and temperature scenarios. Averages are for Dhaka, which is 4 miles from Dhaka. Differentiation was observed for MAMJ in all decades except 2000–2011. ReliefWeb Labs projects explore new and emerging opportunities to improve information delivery to humanitarians. A uniform precipitation distribution was observed for the JAS period, although some changes were observed in the south–east region (Figures 6(g)–6(i)). The daytime temperature is going to reach 29 °c and the temperature is going to dip to 21 °c at night. The north–west and south–southeast areas had higher PCI values (>20). First of all, downloaded the Netcdf file of the data and then crack the NC file by using ArcMap software. In interpolation, the power was considered as 2, the searching neighborhood was standard, the neighborhoods were at least 10 and neighbors to include was 15, major semiaxis was 1.52, minor semiaxis was 1.52, and the angle was 0. Rainfall-related hazards and disasters (like drought and flood) require farmers to implement measures in altering the cropping system, planting or sowing times, crop varieties, and change crop types in the country [43].
