Climate Of Bangladesh
Climate of Bangladesh
Climate is the average weather of
30-year time period for a particular region. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of atmosphere. The Tropic of Cancer passes through the center of Bangladesh and the country's climate can be described as tropical monsoon type - warm and humid in the summer, dry and cool in the winter. The dominant climatic factor for Bangladesh is the monsoon - the distinct change between the wet
(warmer) and dry (cooler) periods.
Three main meteorological seasons are recognized: • (a) Hot or summer season (March-May).
This pre-monsoon season is generally hot and sunny with high evaporation rates. April is normally the hottest month when the maximum temperature may exceed 40°c in the western part of the country. About 15% of the annual rainfall occurs in this season, mainly from thunderstorms or 'norwesters'.
b) Rainy or Monsoon season
(June-October). This is the period of highest rainfall, humidity and cloudiness. Nearly
80 % of the annual rainfall occurs during this season, and in June, the temperature drops due to the cooling effect of the rains. (c) Cool (winter) and dry season
(November-February). This season is characterized by low temperature, low humidity and high solar radiation. January is normally the coldest month when minimum temperature of 5° C may be recorded in the northern part of the country. Only about 5% of the annual rainfall occurs during this season. Mean annual temperature in
Bangladesh is about 25°C. Mean monthly temperatures vary from about 18° C in winter to around
30'C in the pre-monsoon period, while extreme temperatures range between about 5°C and 43° C except near the coast where the sea provides the moderating influence. On average, the country annually receives about 2300 mm of rainfall, varying from 1250 mm in the west to
5500 mm in the extreme northeast. The
