This study aims to assess the spatiotemporal characteristics of agricultural droughts in Bangladesh during 1981–2015 using Effective Drought Index (EDI). Monthly precipitation data for 36 years (1980–2015) obtained from 27 metrological stations, were used this study. The EDI performance was evaluated four sub-regions over country through comparisons with historical drought records identified by regional analysis. Analysis at a level showed that could reasonably detect years/events period....
Time series forecasting of meteorological variables such as daily temperature has recently drawn considerable attention from researchers to address the limitations traditional models. However, a middle-range (e.g., 5–20 days) is an extremely challenging task get reliable results dynamical weather model. Nevertheless, it develop and select accurate time-series prediction model because involves training various distinct models find best among them. In addition, selecting optimum topology for...
Countries depending on small-scale agriculture, such as Bangladesh, are susceptible to climate change and variability. Changes in the frequency intensity of drought a crucial aspect this issue focus research. The goal work is use SPI (standardized precipitation index) SPEI evapotranspiration investigate differences characteristics across different physiognomy types Bangladesh highlight how over time spatial scales when considering geomorphologies. This study used monthly temperature data...
Understanding spatiotemporal variability in precipitation and temperature their future projections is critical for assessing environmental hazards planning long-term mitigation adaptation. In this study, 18 Global Climate Models (GCMs) from the most recent Coupled Model Intercomparison Project phase 6 (CMIP6) were employed to project mean annual, seasonal, monthly precipitation, maximum air (Tmax), minimum (Tmin) Bangladesh. The GCM bias-corrected using Simple Quantile Mapping (SQM)...
Rice husks, abundant leftovers from rice production, offer immense potential as a renewable energy source through thermochemical conversion processes. However, their efficient utilization hinges on understanding unique thermal properties and reaction kinetics. This study addresses critical gap by meticulously analyzing four prominent Bangladeshi husk varieties: BR22, BRRI Dhan46, Dhan47, Dhan49. Through rigorous experimentation, we unveil comprehensive dataset encompassing physical,...

The impacts of climate change on precipitation and drought characteristics over Bangladesh were examined by using the daily outputs from 29 bias-corrected general circulation models (GCMs) under representative concentration pathway (RCP) 4.5 8.5 scenarios. A precipitation-based estimator, namely, Effective Drought Index (EDI), was applied to quantify events in terms severity duration. changes assessed for beginning (2010–2039), middle (2040–2069), end this century (2070–2099) relative...
Abstract This study evaluated the rainfall historical simulations of 15 Global Climate Models (GCMs) Coupled Model Intercomparison Project phase 6 (CMIP6) in replicating annual and seasonal climatology, their temporal variability trends Bangladesh for period 1979–2014, considering ERA5 (ECMWF Reanalysis 5th Generation) reanalysis as reference dataset. Shannon's Entropy decision‐analysis was employed GCMs' rating based on eight statistical indicators a comprehensive metric final grading GCMs....

Statistical downscaling model (SimCLIM) was used ensemble projection in near (2011–2040), middle (2041–2070), far (2071–2100) futures. Modified Mann–Kendall test applied...
Groundwater is a crucial natural resource that varies in quality and quantity across Bangladesh. Increased population urbanization place enormous demands on groundwater supplies, reducing both their quantity. This research aimed to delineate the potential zone Gazipur district, Bangladesh, by integrating eleven thematic layers. Data information were gathered from Landsat 8, digital elevation model, google earth engine, several ancillary sources. A multi-criterion decision-making (MCDM) based...
