IELTS Reading Passage: Tracking Hurricanes

Tracking hurricanes

North American weathermen from the National Ocean and Atmospheric Administration(NOAA)’s Hurricane Research Division have freshly enhanced the achievement rate in their predicting of where hurricanes are likely to strike land by an estimated 15 to 30%. This improvement in precision is due to the use of a tool called GPS-dropwindsonde, which can inquire about the atmosphere neighboring a hurricane while it is still out at sea. The climatic features of hurricanes over land are well realized because an inspection is possible with weather balloons containing cultured weatherman tools. When hurricanes are out of reach of balloons collecting details is decidedly tougher. Little is known of the climate conditions that lead hurricanes in the  direction of land.

A correct assessment of where a hurricane will hit is essential in order to decrease the loss of life and equity. Hurricane Andrew, the most costly hurricane in U.S. history, killed 15 people and caused $35 billion of damages, in today’s dollars, in 1992. But the unnamed: group 4 2 hurricanes, which smacked southeast Florida in 1926 and killed 243 people would have affected an estimated $77 billion if it had struck today. The justification for this is the detonation in population growth and evolution along the South-east coast of the U.S. during the last half-century.Hurricanes happen in cycles every several decades, the last furious period in the U.S. being from 1940 to 1969. ‘Camille’, a class 5 hurricane of such catastrophic force that it led over a billion and a half dollars worth of harm at the time and killed 256 people, hit the coast of the Gulf of Mexico in 1969 with winds over 320 kilometers per hour.  

So far, for the last quarter century, hurricane activity has been almost mild. Analysts do not know the exact reason for the cycles of hurricane activity, but they could be caused by an occurrence called the ‘Atlantic Conveyor’. This is the name given to the huge current of water that flows cold from the peak of the globe slowly along the Atlantic ocean floor to Antarctica and resurfaces decades later prior to flowing back north, fascinating heat as it crosses the diameter. Since hurricanes obtain their energy from the heat of warm water, it is thought that an improvement in the speed of the ‘Conveyor’, as it pulls warm water to the north, is a gauge of add to hurricane activity.The use of GPS-dropwindsondes commence in 1997. Small surmising gadgets dropped from planes at very high distances and over a wide area, they are considerably more divulged than formerly used sensors. Because they weigh only 0.4 kilograms, they are able to stay upward for longer periods and transmit more data to the ground. Each sonde carries its own global emplacement satellite receiver.

The GPS signals received are used to compute the directions and speed of the wind, and data on climate, moisture, and storm gauge pressure at half-second intervals all the way down to the ocean surface.Dropwindsonde details are nourished into an exceptional barometrical computer in Maryland which causes a global computer model of wind design. Data researchers have found a huge changeability in the winds at sea level than formerly believed, but many predicted issues are beyond the solution, at least for the time being.  For example, it is not so far known why hurricanes can immediately change in strength; present-day computer replicas often fail to forecast whether a hurricane will reach land or else cannot spot where a strike will happen.One astonishing result of the latest computer stimulation was the demolition of a huge part of downtown New York. Hurricane analysts believe that the city is more likely than Miami to ache a direct hit in the near future. Also, the unquestionable geographical qualities of the coastline near New York make it imaginable that a wall of water called a storm surge pushed ashore by hurricane winds would cause destructive flooding of Manhattan. A storm surge was in charge of the more than 8000 deaths affected by the hurricane that demolished the city of Galveston in 1900.
