Seasonally four seasons dominated by south-west monsoon, half of the year wind blows from the comparatively cooler humid oceans to the warmer dry land while the other half is prevailed by the wind from cold dry Asian land to the warm Bay of Bengal
The above wind pattern is the resultant thermal effect of the land and sea. So the seasons of Bangladesh is directly influenced by the land and sea interaction. That is why all the natural disasters attains here the highest intensity in terms of disastrous impact
