TROPICAL CYCLONES This past summer has been a very active summer for tropical cyclones. A tropical cyclone “is a
generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation” (NOAA, 2017). Even though tropical cyclones can be classified by location, tropical cyclones can be classified by their intensity because tropical cyclones can be measured by wind speed and barometer pressure. The typical tropical cyclone in the Atlantic ocean is known as a hurricane. Hurricanes have five categories: categories 1, 2, 3, 4, and 5. The differences between these categories are determined by a scale called Saffir-Simpson scale (The Hurricane Watch, 2017).
Categories 1 and 2 hurricanes are the lowest ranked hurricanes. A category 1 hurricane occurs when sustained winds reach between 74 mph and 95 mph. This type of cyclone has winds that can produce some damage. Most living creatures standing outside in the storm could be seriously injured or killed by debris from the storm. (Hurricane, 2015). Some flooding and small pier damage can occur. An example of a category 1 hurricane is Irene in 1999 (Types of hurricanes, n.d.). A category 2 storm occurs when sustained winds reach between 96 mph and 110 mph. This type of storm has winds that will produce more damage than the previous category. Well-built homes may suffer roof and siding damage. High-rise buildings may have its windows broken by debris, which means increased dangers when the storm is over. An example of a category 2 hurricane is Hurricane Frances in 2004 (Hurricane, 2015).
Categories 3 and 4 hurricanes are considered major hurricanes. A category 3 hurricane occurs when sustained winds reach between 111 mph and 129 mph. This type of cyclone has winds that can produce damage to the structure of a well built home. Big trees may be brought down, and flooding becomes a huge problem in coastal areas. An example of a category 3 hurricane is Hurricane Fran in 1996 (Hurricane, 2015). A category 4 hurricane happens when sustained winds reach 131 mph and 155 mph. This type of storm usually produces major beach erosion, flooding in inland areas, and the risk of injury or death is extremely high for living creatures standing outside (Types of hurricanes, n.d.) (Hurricane, 2015). An example of a category 4 hurricane is Hurricane Charley in 2004.
A category 5 hurricane is also a major hurricane, and it is the most destructive hurricane. A
category 5 hurricane occurs when sustained winds exceed 155 mph. This type of storm can produce devastating damage such as: complete building failures, utility failures, blown out windows for most high-rise building, and extensive inland flooding. Utility failures include: power outages which can last for weeks, and shortages in clean and potable water. (Hurricane, 2015). The most recent example of a category 5 hurricane is Hurricane Maria in September and October of 2017.
In summation, hurricanes can be classified by their intensity. They are classified into five
categories, and can have a devastating effect in life. After further examination, it would probably be best if people moved away from these areas and lived in either extreme hot or extreme cold areas.
