Study of the Characteristics and Connectivity of Different Climatic Parameters: Temperature, Humidity, BMD & TRMM Rainfall of Summer Monsoon in Bangladesh

Abstract

This paper attempts to look into the characteristics aspect of different climatic parameters and the inter-relationships among the different parameters in summer monsoon over the region of Bangladesh throughout the last decade using surface data and TRMM satellite data. This study reveals a positive linear relationship between the relative humidity and rainfall and both of them decrease with the increase in temperature and vice-versa over the study region. The yearly mean temperature has increased 0.32˚C and the relative humidity has decreased 0.5% over the last decade. The duration as well as the beginning and endings of summer monsoon both have changed during the study time. Almost identical characteristics features found for TRMM satellite precipitation data and BMD observational rainfall data over the study area.
