Abstract:

The study was conducted for identifying the trend of temperature based on available data from 1950 to 2012 collected from Bangladesh Meteorological Department (BMD). It is found that monthly maximum temperature has a tendency to increase about 0.20C per 100 years. But the monthly mean temperature has a positive trend  to increase about 0.90C per 100 years. On the other hand the trend of monthly minimum temperature reveals the increasing rate of 0.13 per 100 years. Increase of  monthly maximum temperature has been recorded in November at 2.1 0C and  minimum temperature change has been recorded in February at -0.6 0C in the last 100 years. The highest increase of  monthly maximum temperature has occurred as 3.4 0C per 100 years at syedpur and monthly minimum temperature change has occurred as -2.9 0C per 100 years at Rangamati. It is clearly found from the analysis of published data that maximum temperature has been increased dramatically over the last 40 years period.

The warmest month is April and  highest temperature recorded in Bangladesh since 1950 to 2012 at Bogra and Ishwardi in April and May 1956 and 1970 respectively with value of 440C. The coldest month is January in Bangladesh and lowest temperature recorded ever since at Rajshahi on January 2003 with a value of 3.20C. (BMD,2004)

Dhaka has least average temperature than any other division with a value of  10.140C  in January while Chittagong contains the highest temperture with value of  10.640C. Regional analysis of temperature shows that Rajshahi is the warmest area during summer season and Khulna is the coldest region in winter season.
