Introduction Good morning Bahamas, I am Chief Meteorological Officer Jane Doe of the Bahamas Meteorological Department. The Bahamas Meteorological Department is responsible for studying, predicting, and forecasting the weather and climate around the Bahamas. We also are responsible for tracking hurricanes and other weather phenomenon. Over the past few years numerous hurricanes have tremendously affected the Bahamas. Quite often Bahamians contact our department to ask questions about the weather but more specifically about hurricanes. Some of the questions frequently asked are: What is a hurricane? How are they named? How and where are they formed? What strengthens and what weakens hurricanes? What are the different types of storms associated …show more content…

I will also include some of my personal experiences that I have witnessed during Hurricanes Frances and Jeanne in 2004 and Hurricane Wilma in 2005. I am quite certain that this information will be very beneficial to Bahamians by providing the proper knowledge about hurricanes and safety tips on how to survive one of nature’s most violent natural forces. What is a hurricane? How are they formed and named? “Hurricane a’ coming you better batten down! Hurricane a’ coming so big and strong. Hurricane a’ coming you better not be late! You better find shelter ‘cause it’s headed your way.” These lyrics were taken from “Hurricane” a famous song written by Bahamian artist, Phil Stubbs. According to Webster’s New Dictionary, “a hurricane is defined as a violent, tropical, cyclonic storm of the Western Atlantic” (Agnes, 2003, p. 316). Hurricanes are known for being engines of destruction because they cause an extensive amount of damage to the island landforms that they pass over. Hurricanes mainly form over warm oceanic waters 80°F or higher, from 5 to 15 degrees latitude north and south of the equator. Hurricanes …show more content…

7,8 and 10). Most hurricanes form in the Atlantic Ocean because of the above mentioned conditions. When a hurricane is situated in warm water, the intensity of the storm increases because the warm water is the main source of energy along with the moist atmospheric conditions. Hurricane frequency depends heavily on what is called an El Niño. “El Niño refers to appearance of anomalously warm water along the coast of Ecuador and Peru as far south as Lima (12°S)” (Trenberth, 1997, p. 2771). An El Niño causes above average sea temperatures over a period of four consecutive months in the Pacific Ocean. When the El Niño is present this means that conditions are favorable for an active hurricane season. Hurricanes weaken when it moves away from warm tropical water. This happens because the water tends to be cooler, atmosphere is much dryer. Hurricanes also tend to weaken when they move over land because of a lack of water supply and the decreasing surface circulation due to friction. Another factor that causes hurricanes to weaken is wind shear. “Wind shear can be defined as the difference of wind speed over a short distance in the atmosphere” (Melina, 2010, para. 5). High wind shear can cause the heat from a hurricane to dissipate causing the strength of the storm to

For cyclones in the Northern Hemisphere, winds blow counterclockwise and inward. Thus causes Earth’s surface winds to move into the center of the cyclone as air rises. The are going through the expansional cooling process and with that, the relative humidity will increase causing stormy weather to occur in that environment. Critical Thinking 7.

A Nor’easter gets its name from the northwesterly winds that blow in from the ocean. A Nor'easter develops in response to a sharp contrast in temperature between the warm Gulf stream and the cold air from Canada. When the very cold and dry air rushes down and meets the warm Gulf stream, intense low pressure develops. In the upper atmosphere, the strong winds of the jet stream, remove and replace rising air from the Atlantic more quickly than the Atlantic air is replaced at lower level. This activity and the Coriolis force helps develop a strong storm.

Here at the University of Florida, the field of wind engineering is a subject to which a lot of research and manpower is dedicated, particularly concerning hurricanes and the large wind loads associated with them. These powerful storms are generally associated with the eastern and gulf coasts of North America, but they can and do form elsewhere. Hawaii, surrounded by the cold waters of the Pacific Ocean, is not typically associated with hurricane activity, but in September of 1992 the island state was struck by Hurricane Iniki. Within a lifespan of a little more than a week, Iniki was able to completely change the relationship Hawaii had with Hurricanes by battering the islands with strong winds and exposing the complacency fostered by years of mild hurricane seasons. In the years to come, this storm was to serve as the basis for Hawaii’s push to better prepare for potential storms and avoid another disaster of this magnitude.

One of the reason that cause hurricane it’s depend on environment. Hurricane use the warm air and warm ocean as the power of the storm. As being said, the warm temperature that form above the ocean create the rotating wind because when warm air and cool air are touching together then it makes an area of lower pressure, warm air is lighter than cool air so higher air pressure pushes into the lower pressure area and it cause hurricane.
