Why are ledcs more vulnerable to hurricanes

The south-western part of the Indian Ocean experiences 11 or 12 tropical cyclones each year on average. But it did conclude that recent tropical cyclones have been following more southerly tracks before striking the country, perhaps as a result of rising sea temperatures. However, storm surges caused by tropical cyclones across the world are growing in height due to global sea level rise.

The warmer atmosphere can also hold more water, increasing the amount of potential, rainfall during tropical storms. Create one now! Already have an account? Log in now!

The direct or indirect costs from a cyclone can be divided into a number of broad categories, some of which are identified below. Cost of damage. Cost of preparedness. Cost of the warning service. Cost of relief. Loss in business revenue. Losses to agriculture. Economic Gains from a Cyclone Although we tend to focus on the losses due to a cyclone, a complete economic study must also consider the benefits. Two hurricanes lashed Mexico in and caused considerable damage to several communities.

However, the rains filled reservoirs, saved crops and the economic agricultural gains more than offset the coastal losses. In many arid regions in the tropics, a large portion of the annual rain comes from cyclones. Unfortunately, very few studies have focused on this beneficial aspect of tropical cyclones.

Another possible economic benefit of a cyclone is the increase in some businesses during the recovery. In fact, outside aid may prompt a local economic boom in the affected community.

However, the net economic impact on the nation is still negative. Education and knowledge of tropical cyclones must be an essential component in disaster preparedness. Such information must be distributed through the various channels to enhance awareness of the public to the potential threat. Meteorologists should be involved in assuring that tropical cyclone information is accurate, and also play a role in dissemination through briefings, public appearances, etc.

Meteorologists also have a crucial role to play in providing input into the design and implementation of tropical cyclone mitigation systems. This role involves at least three areas of national tropical cyclone preparedness planning. The compilation and issuing of warnings usually entails the conversion of technical information into a proper format and in a meaningful language for different public and special recipients.

Terminology should be well chosen to take into account the physical and human geography of the threatened areas and be conducive to evoking a rational human response to the content of the message. Warnings should be disseminated without delay as the usefulness of promptly compiled and strategically designed user-oriented warning messages can easily be negated if not issued in a timely manner.

Such delays are more critical when the lead time for implementing preparedness measures in safety is limited. The capacity of the community and special user groups to respond effectively to natural disaster warnings is highly dependent on their interpretation of the warning, and on precisely what measures are necessary for the protection of life and property.

Last year, the Caribbean had a record-breaking 30 tropical storms - including six major hurricanes. The World Meteorological Organisation says the region is still recovering. On islands like Antigua and Barbuda, experts say that many buildings have been unable to withstand the intense winds these storms have brought. Several Pacific Island countries were hit by three cyclones between the middle of and January Although it's rare to see so many storms in such a short space of time, experts say sea storms have been growing in strength.

Studies suggest tropical cyclones have become more intense in the past 40 years, but an increase in the overall number of cyclones has not been established. In Uganda, communities in the Rwenzori region have been trying to protect themselves from landslides and floods by digging trenches and planting trees, helping to prevent soil erosion. But a study by the International Institute for Environment and Development IIED , published last month, suggests that the 46 of the world's least-developed countries don't have the financial means to "climate proof" themselves.
