Climatologically Bangladesh is tropical in nature.

Geographically Himalayan range in the north, Bay of Bengal in the south.

  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

MONSOON DEPRESSION OF SEPTEMBER’04

1.    Natural disasters are tropical cyclone, storm surges tornado, severe local storms, floods and flash floods etc.

  Economy is agriculture based , population density is highest in the world, per capita income is low . On the other hand agriculture is very vulnerable to weather and climate impacts. So the impacts of natural disasters worsen the poor –section of the people whose livelihood depends on agriculture. 

Recently centralization and urbanization has a growing tendency. So every year city/town has to accommodate a large number of people from villages who loose their livelihood , accommodations due to natural disasters or some kind of social systems that also has link to natural disasters.

  We need very responsive disaster management system. To do this we need that effective early warning system of the disasters.

  BMD is responsible for this job.
