Abstract
In this study, the contribution of El Niño–Southern Oscillation (ENSO) to the rainfall and temperature over Bangladesh has been investigated. Rainfall, temperature, and ENSO data have been used for a period of 60 years (1958–2017). This paper examines the spatial distribution of rainfall and temperature across Bangladesh and the results suggest that the distribution of rainfall and temperature varies with seasons. A geographically weighted regression, Student’s t test, correlation coefficient, and cross-wavelet transform were used to reveal whether different types of ENSO contribute strongly or weakly to rainfall and temperature in Bangladesh. Findings indicate that the ENSO has a strong connection with rainfall and temperature over Bangladesh.
