equator‚ these cyclonic patterns may become tropical cyclones. These are among the most powerful and destructive phenomena on earth. A major cyclone may release energy at the rate equal to 25 hydrogen bombs every second. In the eastern hemisphere‚ tropical cyclones are called typhoons‚ from the Chinese ‘tai fung’‚ and in the west they are known as hurricanes. 4. Seawater needs to be at a temperature of at least 270C for a tropical cyclone to form. Water vapor condenses into clouds and the air

REMOTE SENSING AND GIS IN DIASTER MANAGEMENT INTRODUCTION Satellites monitoring Earth’s resources and natural disasters. Each satellite has different repeat pass frequency and spatial resolution (unless it belongs to the same series of satellites for the purpose of continuation of data flow with same specifications). Similarly‚ different satellites have different types of sensors on-board‚ such as‚ panchromatic‚ multispectral‚ infrared and thermal. All these sensors have applications

To what extent can preparedness mitigate the impacts of tropical revolving storms? (40 marks) Tropical revolving storms can be referred to as Hurricanes‚ cyclones and Typhoons these occur in the Atlantic‚ Indian and pacific oceans. Nobody is quite sure how they form but certain factors do need to be met for one to form. One of these is the temperature of the sea which has to be above 28degrees‚ the water also has to be deep beneath the storm‚ this is how the storm gathers its energy. These storms

cylones: In meteorology‚ a cyclone is an area of closed‚ circular fluid motion rotating in the same direction as the Earth.[1][2] This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure.[3][4] The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic

history will tell us that one is possible‚ but it can’t say when one will occur‚ or at what time‚ or at what magnitude With tropical cyclones we know of the existence of a storm about 7 or 8 days in advance‚ but there is still great uncertainty about exact location of landfall until 24 hours before. Useful tools: satellites- ability to see where tropical cyclones are or where a volcano begins to heat up. Satellites are also used in making predictions about the potential for an area to burn. The

Rowan Ferguson Using examples‚ Examine the success of different approaches to manage tropical storms (hurricanes and cyclones) When discussing management strategies‚ it is important to use a system to categorise various approaches. In reference to a natural hazard there are number of ways management schemes attempt to deal with these events. Management schemes can modify the event; decrease its severity or alter its course or even incidence‚ they can modify the vulnerability: prepare for and

rain‚ and the arrival of both can cause evacuations‚ emergency warnings and general chaos. But there are numerous differences between the two weather systems‚ from the elements that form them to the type of devastation they leave behind. The confusion between a tornado and a hurricane may stem from a common nickname- cyclone. Technically speaking‚ a true cyclone is a hurricane which forms in the Pacific Ocean. Some suggest that a cyclone is a high-pressure storm system while a hurricane is a low-pressure

Haiyan‚ also known as Typhoon Yolanda in the Philippines‚ was an extremely powerful tropical cyclone that devastated portions of Southeast Asia‚ primarily the Philippines‚ with surprising destruction in early November 2013. Typhoon Haiyan struck the Philippines as a category five super typhoon‚ with winds traveling at a record high of 195 miles per hour‚ and has been recorded as the fourth largest tropical cyclone in history. Typhoon Haiyan not only overwhelmed the Philippines‚ but also neighboring countries;
