FURY OF NATURE !!!
The fiery nature
calmed down spelling destruction with the recent Earthquakes. Hardly people have come out
from the doom and here strikes again the Cyclone threat to Gujarat in May
2001.
The Killer Storm with its giant waves hit the Coastal regions of
Gujarat and parts of Rajasthan in June 98) with a speed of 120-150 kmph, made a havoc with
a high death toll, destruction and damage. 70 kmph cyclonic winds hit Mumbai and eastern
parts of Pakistan too was gripped with the dreaded Cyclonic storm. Cyclone is normally a
term applied to winds rotating around low pressure regions. Cyclone is more loosely
applied for a storm and disturbance, particularly Hurricane and Typhoon which centre on
areas of usually low pressures. They usually occur after a hot season in an unstable but
horizontally uniform air mass. Hurricanes consist of high velocity of winds that blow
circularly around a low pressure centre in the sea known as eye of the storm. The low
pressure centre develops when the warm saturated air prevalent in the doldrums is underrun
and forced upon by dense cooler air. Atmospheric pressure drops sharply and wind velocity
rises. The strength of such Cyclonic Hurricane is rated from 1 to 5; the mildest category
1 has the winds of at least 120 kmph (74mph) and the strongest and rarest category 5 has
winds that exceed 250 kmph (155mph). Within the eye of the storm, average 24 kms diameter,
the winds stop and clouds lift off but the seas remain violent. The air causes a clockwise
(anti clockwise in northern Hemisphere) air spiral which gushes towards high level
regions. Rainfall too, can be heavy with heavy seas in coastal areas e.g. Bay of Bengal.
This causes havoc, loss of life, uprooting trees, electric poles, buildings as the Cyclone
sweeps its way and panic grips for survival. Extreme spiralling of winds is termed as
Tornado which has speed upto 450 kmph ( 250 mph) funnel shaped, moving 100 metres wide and
usually short lived. The system for tracking the Cyclonic Hurricane was developed in mid
1950. Due to improved systems of Radar, satellites and so on, predictions and
communication have been able to minimize loss of life but property damage is heavy in
coastal regions. The strongest ever Hurricane to hit western Hemisphere in 20th Century
was Gilbert that devastated Jamaica and parts of Mexico in 1988 with winds
that gusted up to 350 kmph. |
TWISTS IN THE
WINDS - Happennings!
On May 29, 1986, 12 school children
in West China were sucked up by a Tornado. It put them down again on some sand dunes 20
kms away - completely unharmed!

An Average 708 Tornadoes strike
United States. In April 1974, 148 Tornadoes savaged 13 states in just 24 hours!

A Policeman helped a driver of a
vehicle who had been a victim of a tornado. He noticed a kitten in the back seat of the
car who was not a passenger before the Tornado. The owner of the kitten came to the spot
after a few minutes and claimed his pet.

More than 940 Villages of Kutch,
Porbandar and Jamnagar Districts suffered a after effects of the Cyclonic storm with
damages mounting to Rs.225 crores and more.
