MONSOON DEPRESSION OF SEPTEMBER04

• 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

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.

? So our economy, infrastructure is very
vulnerable to natural disasters. Now the question
how to reduce this impacts?  ? 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.  ? How BMD is performing their job?  ?
Whether they are fully capable of doing
this? 7
