Climatic hazards prediction and prevention
"Hazard prediction and prevention is the key to lifting the threat off climatic hazards". Discuss this statement with reference to case studies.Climatic hazards are a result of cyclonic activity.A tropical cyclone is a system of intense low pressure known locally as hurricanes, typhoons and cyclones. They develop: Between latitudes 5 degrees and 20 degrees north or south of the equator.This knowledge helps the areas at risk prepare for the possibility of a tropical cyclone.A hurricane is a tropical cyclone, which generally forms in the Atlantic and is accompanied by thunderstorms and a counterclockwise circulation of winds. Hurricanes are strong winds that exert a pressure of at least 70kg/m . The wind speed causes both pressure and suction forces. Pressure increases with wind speed. This pressure is worsened by wind gustiness, which can cause fatigue in building materials that would withstand steady stress.Diagram of a hurricane/ tropical cyclone. Storm surges - which can increase the mean water level 15ft or more. Inland flooding - responsible for half the death
Track forecasts have improved by about 1 percent per year, but the 3-4 percent population growth could overwhelm these better predictions, resulting in higher casualties again. Longer periods of wind stress are more likely to cause failure of structures. However, new concerns have emerged as coastal population growth and property development has exploded during this period. The main source of information on a hurricane is a reconnaissance plane that flies into the hurricane's eye. Mudslides are also often a problem in hilly terrain, burying homes and destroying property, particularly in underdeveloped mountainous countries where the warning system, hurricane preparedness, and infrastructure are insufficient. Wind direction can affect damage rates. Research has shown that the violent tornadoes can occur at anytime. Likewise, during drought years major hurricane activity is reduced. As in the Solomon Islands disaster, the country is very poor so could not afford prediction systems like the ones set up in America. Although, Hurricanes can suddenly turn, speed up, slow down, stall, or loop trapping many residents in the effected area. In general, this area has a history of hurricane-induced fatalities: 300,000 people were killed near Calcutta, India in 1737; 20,000 were killed in Coringa, India in 1881; and 200,000 were killed in Chittagong, Bangladesh in 1876. Tornadoes in Florida are quite predictable as they occur in two main seasons. There is a NOAA Weather Radio, which can be purchased for any home. They issue a Hurricane Warning that indicates that the state of Florida will be receiving winds of at least 74 mph within the next 24 hours.
