Hurricanes have become such a tragedy in the world today. They cause a lot of damage to property and destroy scores of human and aqua habitats. A hurricane is a storm that is characterized by intense spiraling winds. It is mainly caused by the effect of atmospheric pressure and the temperature at the ocean surface. Once it sees its onset, a hurricane can last for one day to one month, but there are those that have taken only a few hours such as Ernesto of 2006 which lasted for only twelve hours. The sharp spiraling winds of a hurricane travel at very high speeds averaging between 75 to 200 mph. The hurricane storm covers almost 600 miles across as it forms an eye-shaped structure that has the lowest pressure at its center and covers 10-20 miles per hour over the open ocean. This paper looks at the environmental factors that develop at the sea at various times of the year and result in seasonal hurricanes. Heat budget helps in regulating the amount of heat being absorbed into the earth, and that radiated outside the earth. The heat budget is responsible for controlling the surface temperature of an ocean. When the surface temperature of an ocean rises, the amount of water being vaporized into the atmosphere consequently rises. Once the water is evaporated condenses forming dense clouds that cause rain. For hurricanes to occur there must be high winds moving in the same direction at a speed that causes the formation of storm clouds. Hurricanes require tropical waves, and their intense energy helps them spin into a complete circle (Villarini, Vecche & Smith, 2013). When the heating budget does not regulate the heating temperature of the ocean, it initiates the evaporation process causing the formation of clouds that can result to a hurricane. The hurricanes that have occurred in the North Atlantic have been noted to be seasonal mainly from winter to the beginning of the summer season. The storms are known to occur between June to December frequently because that is when the surface temperature of the ocean is always warm, and it is followed by occurrences of tropical cyclones that increase the rising of the moist air that evaporate from the ocean (Wang et al., 2012). The occurrence of the tropical cyclone begins in June but usually increases as the season advances. The high numbers of hurricanes experienced are generally from September to November. Although it is easy to tell the seasons when hurricanes are most likely to occur, there are cases where they occurred before the onset of the season in months like April, March, and May. Hurricanes are spread by the global winds that blow from east to west. Tradewinds coming from the coast of Africa, contribute to the formation of Atlantic hurricanes. The storms formed in the Atlantic are carried westwards to the United States and the Caribbean (Pielke, 2013). The direction that the storm takes can only be determined when the trade winds are strong as opposed to when they are weak. Other factors that affect the course of the storm include high-pressure systems and Coriolis Effect. The Coriolis Effect can determine the direction of the storm like in the Northern Hemisphere the storm goes northward. In conclusion, a hurricane is disastrous and can cause many losses like lives and economic loss. Hurricanes can be prevented or minimized when keen weather study is done to monitor the flow of the wind, the surface temperature of the ocean, and the pressure system. Hurricanes have occurred off seasons which means that sometimes it can be hard to determine the tropical depression or disturbance that can lead to the formation of hurricanes. It has also been noted that for a hurricane to occur there have to be many factors involved other than the tropical cyclone.
