India is one of the most DISASTER PRONE countries of the world. The geographical
location and its natural landscape make it vulnerable to a number of natural disasters.
Nearly half of India lies in the tropical zone and the rest half in the temperate
zone. The tropical cyclones bring disasters in terms of death and destruction.
A cyclone is a powerful swirling storm that measures from 300 to 500 kms in diameters.
The wind in the center of a cyclone below at a speed of 120 kms per hour. Many cyclone
have caused widespread deaths and destruction. Cyclonic winds swirl around the eye
a calm area in the center of the storm. The eye of a cyclone measures over 30 kms
in diameter and has few clouds.
Cyclones are roughly circular or oval in shape and they originate as a wave along
the front separating two air masses of different temperature, density and direction.
They bring rainfall because a warm moist air is made to rise over a mass of cold
air.
The cyclone below in COUNTER CLOCKWISE direction in the Northern Hemisphere and
CLOCKWISE direction in the Southern Hemisphere.
A cyclone is an area of low pressure in the center and high pressure outside. They
develop over tropical regions of North Atlantic Ocean, North East Pacific Ocean
and the Indian Ocean. The cyclones are known by different names over different parts
of the world. They are known as TYPHOONS in China, HURRICANES in Central America,
WILLY WILLIES in Australia and CYCLONES in India.
Consequences Of A Cyclone
Due to strong cyclone winds trees are uprooted, telephone and electricity lines
are snapped, poles are tilted and the entire communication system suffers.
Standing cops in the fields suffer damage. Heavy rains cause flash floods due to
which people, animals and properties are washed away.
Weak structures or buildings collapse. Sea waves also become huge and hit the coastal
areas badly.
After the death and destruction, epidemic diseases start spreading and thus affect
human life.
Cyclone Warning And Forecasting
During the cyclone season the India Meteorological Department (IMD) keeps a close
watch on the weather conditions developing over the Arbian Sea, Bay of Bengal and
Indian Ocean. They also examine the pictures of the area taken by weather satellites
and collect information such as air pressure, temperature, wind speed and direction.
On the basis of this, information forecasting is done. Timely warnings issued by
IMD helps the administration to prepare contingency plans and evacuate people from
the affected area.
Managing Cyclones
If you are living in an area where CBDP exercises have taken place, ensure:
Vulnerability list and maps have been updatedCyclone drill including search & rescue, first aid training have taken placeStock of dry food, essential medicines and proper shelter materials maintained
Upon a cyclone warning
Store loose items inside. Put extra agricultural products/ stock like paddy in plastic
bags and store it by digging up a hole in the ground, preferably at a higher elevation
and then cover it properly. Fill bins and plastic jars with drinking water.Keep clothing for protection, handyPrepare a list of assets and belongings of your house and give information to volunteers
and other authorities about your near and dear ones.Fill fuel in your car/motorcycle and park it under a solid cover. Tie bullock carts,
boats securely to strong posts in an area, which has a strong cover and away from
trees. Fallen trees can smash boats and other assets.Close shutters or nail all windows. Secure doors. Stay indoors, with pets.Pack warm clothing, essential medications, valuables, papers, water, dry food and
other valuables in waterproof bags, to be taken along with your emergency kit.Listen to your local radio / TV, local community warning system for further information.In case of warning of serious storm, move with your family to a strong pucca building.
In case of warning of cyclones of severe intensity, evacuate the area with your
family, precious items and documents and emergency kit. Take special care for children,
elders, sick, pregnant women and lactating mothers in your family. Do not forget
your emergency food stock, water and other emergency items.
GO TO THE NEAREST CYCLONE SHELTER.Do not venture into the sea for fishing.
On warning of local evacuation
Based on predicted wind speeds and storm surge heights, evacuation may be necessary.
Official advice may be given on local radio / TV or other means of communication
regarding safe routes and when to move.
Wear strong shoes or chappals and clothing for protection.Lock your home, switch off power, gas, water, and take your emergency kit.If evacuating to a distant place take valuable belonging, domestic animals, and
leave early to avoid heavy traffic, flooding and wind hazards.If evacuating to a local shelter or higher grounds carry the emergency kit and minimum
essential materials.
When the cyclone strikes
Disconnect all electrical appliances and turn off gas.If the building starts crumbling, protect yourself with mattresses, rugs or blankets
under a strong table or bench or hold on to a solid fixture (e.g. a water pipe)Listen to your transistor radio for updates and advice.Beware of the calm `eye’. If the wind suddenly drops, don’t assume the cyclone is
over; violent winds will soon resume from the opposite direction. Wait for the official
“all clear”.If driving, stop – but well away from the sea and clear of trees, power lines and
watercourses. Stay in the vehicle.
After the cyclone
Do not go outside until officially advised it is safe.Check for gas leaks. Do not use electric appliances, if wet.Listen to local radio for official warnings and advice.If you have to evacuate, or did so earlier, do not return until advised. Use a recommended
route for returning and do not rush.Be careful of snakebites and carry a stick or bambooBeware of fallen power lines, damaged bridges, buildings and trees, and do not enter
the floodwaters.Heed all warnings and do not go sightseeing.
Relief And Rehabilitation
Relief and rehabilitation should be immediately provided to the people who suffered
due to the cyclones.
Relief camps should be organized for such people in the community centers or in
nearby school buildings. Arrangement should be made to provide them with food and
shelter.
Administrative response at the national, state and the district levels should be
very quick.
Assessment of damages in respect of every individual should be done and the government
should provide monetary assistance so that the affected people can start their life
again. NGOs should also come forward to help such people so tat they are properly
rehabilitated.
