bangladesh rainfall data 2018

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]. 2018, Article ID 1849050, 18 pages, 2018., 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. 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. For short time periods, precipitation was strongly linked to season. Annual Weather Averages Near Dhaka. The annual trend of PCI has increased by maximum in majority of the stations for most of the periods whereas the SupraSeasonal PCI of July–December has decreased in two third of the stations (Table 2). The inverse distance weighting (IDW) is an established deterministic method for the precipitation concentration index mapping and one of the most frequently used deterministic models in spatial interpolation [35–37]. Anarul Haque Mondol and Al-Mamun designed the research idea, analyzed the data, and wrote the manuscript; Mehedi Iqbal contributed for critical evaluation of the manuscript. The major objective of this research was to analyze rainfall trend and irregular distribution over the study area at various temporal intervals. The annual PCI values were moderate with some irregularities (Figure 2). For the six-month period of JD, a moderate precipitation distribution was observed. List of alerts, ongoing and past disasters covered by ReliefWeb. Owing to the height of this plateau, uplifted moisture condenses, leading to particularly heavy rainfall over northwestern Bangladesh [33]. First of all, downloaded the Netcdf file of the data and then crack the NC file by using ArcMap software.

The decadal analysis (1980–1989, 1990–1999, and 2000–2011) showed that the annual PCI values have varied over time and exhibited irregular distributions. 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. This page includes a chart with historical data for Bangladesh Average Precipitation. 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)). 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. Generally, all stations were found to be homogeneous; therefore, the datasets from each station were included in this analysis. Depending on the season, the average daytime temperatures range between 25 … 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. This is widely recognized by the world community. The PCI values were calculated on an annual scale for each grid point using data from all stations based on the equations of Oliver [27]:where is the total precipitation in month i. BD, Bangladesh; NNWR, north-northwest region; CR, central region; ESER, east-southeast region; SSWR, south-southwest region. 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. ... API - Real-time data stream to power next-generation apps. It is mainly focused on the development of models for long term rainfall prediction of Bangladesh divisions and districts (Weather Stations). The results from two-month data analysis showed relatively moderate-to-uniform precipitation distributions and no strong irregularities for any region (Figure 2). Anarul Haque Mondol, Al-Mamun, Mehedi Iqbal, Dong-Ho Jang, "Precipitation Concentration in Bangladesh over Different Temporal Periods", Advances in Meteorology, vol. The Climate Research Unit (CRU) data are also used for understanding of the model performance. The average temperature in Dhaka is 25.9 °C | 78.6 °F. On average, December is the driest month.
