Cyclone Nargis is the deadliest tropical storm in the
recorded history of Burma (Myanmar). It
devastated many areas in Burma, as well as some
areas in Sri Lanka, Bangladesh and India.
The main features of a cyclone are: the eye, the
eyewall and rain bands. The eye is situated at the
very centre of a cyclone and is a region of mostly
calm weather. Surrounding this is the eyewall, a
ring of towering thunderstorms where the most
severe weather occurs. Rainbands are compact
regions of vertical air movement, which spiral into
the centre of the cyclone.
Cyclones are made from a simple thunderstorm,
with full cooperation from both the ocean and the
atmosphere. The water in the ocean must be
warmer than 26.5 degrees Celsius. The moisture
and the heat from this hot water is the ultimate
source for cyclones.
The official estimate of the death toll of the cyclone
is now more than 20,000, with a further 41,000
missing and as many as 1 million have been left
homeless. Approximately 2.5 million people have
been severely affected by the cyclone and its
aftermath.
Cyclone Nargis caused catastrophic destruction to
the Burmese landscape. Thousands of buildings
have been flattened, power lines downed, trees
uprooted, roads blocked and water supplies
disrupted.
It was extremely hard for the emergency responses
to help the people in Burma because the
government would not let anyone into the country.
Even when they eventually did gain entry into the
country, the government insisted on distributing
aids by themselves.
