This work was supported by the Ministry of Education of the Republic of Korea and the National Research Foundation of Korea (NRF-2016S1A3A2924243). The base data for this work has been collected from Bangladesh Meteorological Department. Precipitation concentration varies within the country, and the mean annual precipitation varies from a maximum of 5,690 mm in the northeast to a minimum of 1,110 mm in the west [21]. Rainfall in Bangladesh during the monsoon season is driven by tropical depressions in the Bay of Bengal [33]. Although there is no single research method that can comprehensively examine changes in precipitation over time, it is worth considering how different methods can be applied to certain situations [24]. The summers here have a good deal of rainfall, while the winters have very little. It has been suggested that water cycle modification is one of the most notable consequences of global atmospheric warming [6].

Most climate research has suggested that annual rainfall will increase and winter rainfall will decrease in South Asia owing to global climate change [40, 41]. Daily maximum temperature and normal daily rainfall data were collected for north-western region of Bangladesh for the period 1981-2008. Generally, all stations were found to be homogeneous; therefore, the datasets from each station were included in this analysis. The OND period showed the strongest irregularities in precipitation distribution during 2000–2011 (Figure 6). 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]. The highest rainfall -- 142mm -- was recorded in Sitakunda in the last six hours. RW COVID-19 page: Find latest updates on global humanitarian responses.
