A statistical analysis on the contribution of El Nino-Southern Oscillation to the rainfall and temperature over Bangladesh

In this study, the contribution of El Nino-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.

Automated summary

This study investigated the contribution of El Nino-Southern Oscillation (ENSO) to rainfall and temperature in Bangladesh using data from 1958 to 2017. The results showed that ENSO has a strong connection with rainfall and temperature variations across seasons in Bangladesh. Various statistical methods were employed to analyze the impact of different types of ENSO on the climate of Bangladesh.
