Typhoons and Its Damage

TYPHOONS
Typhoons destroy about 1.5% of the national product of South East Asian countries every year. Much of this damage cannot be avoided, even using the most modern technology.

However, because of the need to give people as much warning as possible, an international network of  meteorological stations keeps watch on the movement of typhoons. A typhoon warning centre, established by the UK on the island of Guam in 1959, regularly sends aircraft into suspected storm areas to measure winds, movement and pressure.

Orbiting continuously around the world, satellites take pictures and plot changes in the direction of storms. However, problems still remain because 24-hour forecasts of storm movements can be inaccurate by as much as 100 miles, and 3-day predictions are often 300 miles off course.

 

For example, in 1960 Typhoon Mary appeared to be heading for land about 70 miles west of Hong Kong, but it changed course during the night and smashed  through the centre of the area in the early hours of the morning. This typhoon left 11 people dead, 11 missing, 130 injured and about 300 boats sunk or wrecked. Another example is Typhoon Vera, which crashed across Taiwan on August 1, 1977. It left 38 people dead and 175 injured, and crippled the seaport city of Keelung.

Power supplies to about 60% of Taipei’s two million people were cut for about two days and the enormous gales flattened 54 houses. They partially damaged another  in the island’s northern and central areas.

Among other effects, two major fires broke out in Taipei City and one of these burned down  stores. Needless to  say, the cost of all this damage was enormous and disasters of this kind are unfortunately repeated many times a year throughout the world. Control of typhoons lies in understanding them better. Good predictions are a method of control because action can be taken to limit their destructive force.

For better understanding and improved  predictions of typhoons, scientists must learn much more about tropical weather, and some major research projects, such as the Global Atmospheric Research Programme, begun in 1974, are now under way. Meteorologists also consider the possibility of modifying the typhoon’s direction by seeding hurricane clouds to force them to release  their rain before they would under normal conditions.

However, researchers in Asia are doubtful about the advisability of interfering with typhoons although they cost the region a great deal in money and lives. They warn that because man does not yet have sufficientknowledge, he should not yet begin large-scale weather  modification.

Much of Asia’s vital food-growing areas lie in easily flooded, open delta lands along the sea coast and so any substantial change in weather patterns could have potentially disastrous effects. It is estimated that as much as 25% of the water required for Asian paddy fields and reservoirs comes from typhoons, and so it seems better to  have typhoon damage than to have no typhoons at all.

For example, in the autumn of 1974, Hong Kong residents were warned to prepare themselves for water rationing. The reservoirs were very low because of a long drought. The outlook was bad, but then two typhoons in a month provided Hong Kong’s reservoirs with 22 billion gallons of  water. Since typhoons cannot be prevented, the best that can be done is to develop typhoon warning systems, such as the one in Hong Kong itself.

 

In 1975, a number of other Asian nations requested typhoon predictions from Hong Kong and a computer now helps in the 55 preparation of these valuable forecasts. Prediction is not the only important issue, however. For the community to be prepared for a typhoon is as important as a warning. Countries are now encouraged to create their own national disaster organisations, which will respond to emergencies with temporary housing, food, medical aid and communications.

People in vulnerable coastal villages are being taught how to build large safety mounds higher than the flood level in order to protect themselves against flooding.
