ABSTRACT Satellite‐derived lightning data for 17 years (1998–2014) were used to evaluate the relation between environmental factors and activity over Bangladesh landmass. Time series convective available potential energy (CAPE) extracted from ERA‐40 reanalysis while total rainfalls obtained Tropical Rainfall Measuring Mission's monthly products. In addition, product of CAPE precipitation was computed as an additional variable. Three timescales – monthly, seasonal annual utilized determine...
Abstract Although coastal and inland areas of Bangladesh exhibit distinct physiographic climatic characteristics, spatiotemporal variation extreme events is poorly understood in these two areas. This study was an attempt to understand the trends over period 1968–2018. The missing data daily maximum minimum temperature, rainfall datasets were imputed using multiple imputation by chained equations technique implementing a predictive mean matching algorithm. then tested for inhomogeneity...
Abstract Providing Regional Climates for Impacts Studies (PRECIS) is a regional climate model, which used the simulation of regional‐scale climatology at high resolution (i.e. 50‐km horizontal resolution). The calibration rainfall and temperature simulated by PRECIS performed in Bangladesh with surface observational data from Meteorological Department (BMD) period 1961–1990. Climate Research Unit (CRU) also understanding performance model. results 1961–1990 are as reference to find variation...
Abstract Characteristics of precipitation systems in and around Bangladesh are analysed using 6 years radar data from the Meteorological Department (BMD). Precipitation classified as arc, line, or scattered types according to their shape; then small, medium, large length; stationary, slow, fast propagation speed. Arc‐, line‐, scattered‐type found 230 (29%), 117 (15%), 442 (56%) times, respectively, April September during analysis period (2000–2005). These arc‐, have average speeds 11.0, 7.1,...
Abstract Urban-induced land use changes have a significant impact on local weather patterns, leading to increased hydro-meteorological hazards in cities. Despite substantial threats posed humans, understanding atmospheric related urbanisation, such as thunderstorms, lightning, and convective precipitation, remains unclear. This study aims analyse seasonal variability of cloud-to-ground (CG) lightning the five large metropolitans Bangladesh utilising six years (2015–2020) Global Lightning...
To explore the teleconnections between Bangladesh summer monsoon rainfall (BSMR) and sea surface temperature (SST) anomalies over different parts of ocean have been examined from years 1961–2008 (48-year). Global NCEP/NCAR reanalysis data SST used at 2 degree by grid in this study. A significant positive correlation (0.44) was found BSMR southwest Indian Ocean (around 30° S) month February. All other monthly (January to May) correlations were not be significant. The Bay Bengal positively...
