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.

厄尔尼诺-南方涛动对孟加拉国降水和气温贡献的统计分析

在这项研究中，研究了厄尔尼诺-南方涛动 (ENSO) 对孟加拉国降雨和温度的贡献。降雨量、温度和 ENSO 数据已使用了 60 年（1958-2017 年）。本文研究了孟加拉国降雨量和温度的空间分布，结果表明降雨量和温度的分布随季节而变化。地理加权回归、Student t 检验、相关系数和交叉小波变换被用来揭示不同类型的 ENSO 对孟加拉国的降雨和温度的影响是强还是弱。调查结果表明，ENSO 与孟加拉国的降雨和温度有很强的联系。
