The number of days for different ranges- or thresholds of temperature and rainfall are also calculated. Monthly distribution of rainfall over Bangladesh is shown in Figure 1(b). Dhaka, Bangladesh, January 12-14, 2019 Page | 255 MULTIVARIATE ANALYSIS ON MONTHLY RAINFALL OVER BANGLADESH Md. As a result, rain over the entire Ganga and Brahmaputra and minimum temperature, dry bulb temperature, rainfall and wind (direction and speed) are calculated for different stations of Bangladesh Meteorological Department (BMD) during the period 19812010. The most striking feature of its climate is the reversal of the wind circulation between summer and winter, which is an integral part of the circulation system of the South Asian subcontinent. The Monthly Rainfall Totals are rainfall data collected from the U.S.-Affiliated Pacific Islands (USAPI).Providing up-to-date information on climate variability related to the ENSO climate cycle for their respectable regions.
