How Global Warming and Hurricane are related - Essay Example
Global warming and Hurricane are interrelated in terms of climatic natural obsession as the strongest hurricanes in the present climate may be upstaged by even more intense hurricanes over the next century because the increasing levels of greenhouse gases in the atmosphere warms the earth's climate…
Continuation of historical trends of greenhouse gas emissions will result in additional warming over the 21 century, with current projections of a global increase of 2.5F to 10.4F by 2100, with warming in the U.S. expected to be even higher.
Hurricanes, tropical cyclones or typhoons, which can be defined as closed-circulation, warm-cored, low-pressure systems with maximum sustained surface wind speeds (1-minute mean) of at least 39 mph, are intense tropical storms with sustained winds above 74 miles/hour (Ahrens, C. Donald. Meteorology Today1) and are conventionally divided into two intensity classes: tropical storms (with maximum winds of 39-73 mph) and hurricanes (with maximum winds of at least 74 mph). Hurricanes have been subdivided into five potential damage classes depending on their maximum wind speed, minimum central pressure and storm surge magnitude.
Sea level is rising and will continue to rise as oceans warm and glaciers melt. Rising sea levels means higher storm surges, even from relatively minor storms, causing coastal flooding and erosion and damaging coastal properties. In a distressing new development, scientific evidence now suggests a link between hurricane strength and duration and global warming. ...
