Extract of sample "Hurricanes"

Hurricanes Hurricanes are generated when the radiation of the sun heats tropical waters causing air to rise as it grows warmer. The heat enables the air or the water vapour to rise with great speed then initiates to rotate counter-clockwise in twelve hours at which time span the formation of winds may be expected to take place with greater strength and rate of whirling motion. Such movement may be classified as forming a light breeze with winds at slow pace, fresh breeze if slightly faster, and a high wind beyond this rate. As a result, when the moist warm air at the ocean surface evolves to meet the cooler land air, a 74-mph tropical storm known as the hurricane may come into being. The latent heat release brings about temperature increase for the cooler atmosphere above through condensation and since this occurs in cycle, humidity of the warm ocean air augments and blends with the accumulating storm that eventually becomes the hurricane. Scientific studies also attribute the creation of a hurricane from elevated wind speed due to atmosphere at higher altitudes where high pressure exists as well.
Global warming via greenhouse gases naturally impacts oceans, such as the North Atlantic and the northern Indian ocean, with rise in temperature, thereby contributing to the change which favors strengthening of storms with wind speeds that could reach the maximum. Under these circumstances, hurricanes may be produced significantly whenever the wind shear profile, not necessarily the water temperature, gains an advantage through the global warming which normally enhances to the huge quantity of energy exchanged between the ocean and the air on its top. Consequently, “As water warms, the ability of water to evaporate goes up, and a greater evaporation rate will produce a more intense hurricane” according to MIT meteorologist Kerry Emanuel.

... water in the tropical region. Water is usually 800F (270C) in this part of the earth. In a year, four hurricanes develop in the Atlantic region and an approximate of sixty hurricanes rise from tropical seas and swirls through the globe. Coastal areas are the most prone to danger because hurricanes are formed in the sea. Hurricanes in the United States mostly come from the tropical and subtropical waters of the Pacific Ocean, the Gulf of Mexico, the CaribbeanSea and the Atlantic Ocean. Some are small and others are large. But whatever the case, hurricanes are the mightiest of all storms. Hurricanes are natural phenomena that can be dangerous and destructive but is perfectly designed by nature to serve a purpose. It is essential to maintain...

Hurricanes an anticlockwise direction. There are different categories of tropical cyclone based on their average speed, whereby tropical depression have a speed of up to thirty eight miles for every hour, tropical storm have a speed of seventy three miles per 60 minutes and are then termed as hurricanes if their speed exceeds seventy four miles for every hour. In addition, there are different classifications of hurricanes determined by their speed, whereby hurricanes with a speed between 74 to 95 miles per hour are a weak hurricane and that with a speed of above 155 miles per hour is a strong one. Furthermore, they vary in their width and size but usually...

Natural Hazards and Disasters : Hurricanes

...? Natural Hazards and Disasters – Hurricanes Natural Hazards and Disasters – Hurricanes Explain the formation and movement of hurricanes A hurricane is defined as a powerful, rotating storm that forms near the Equator over warm oceans. Often, Hurricane travels from ocean to the coast and on to land, where rain, wind, and huge waves can result to extensive destruction (Cauffman,2006).Hurricane are classified in different categories depending on they strength and destruction. The scale ranges from category one to five. Category 5 is the deadliest of all. Basically, hurricanes start as a collection of tropics storms over the ocean. Moist air and thermal energy from the ocean surface, high atmospheric pressure atmosphere and convection lifts...

...on the formation and characteristics of the hurricanes. Introduction A hurricane assembles energy as it progress across the ocean water, drawing up warm, moist tropical air from the surface and supplying breezy air aloft. The Coriolis force is essential in the creation of a hurricane although the force becomes weak near the equator. Thus, hurricanes can never form at the equator. Hurricanes typically haves an average diameter of about 500 km (311 miles) with strong winds spiraling inward and upward at speeds that range from 75 to 200 mph (Ahrens, 2007). Hurricanes usually start as tropical disturbances in warm ocean waters with...

Comparison and Hurricanes

...Comparison Hurricane Sandy lived up to its billing as a ‘Frankenstorm’ labeled by various media houses. The storm hit the East Coast of United States on October 29 and estimated to have cost $ 20 billion dollars in damage. The Hurricane affected no less than 24 States (The Red Cross). Moreover, some of its devastating effects included power outages, destruction of buildings and extensive flooding of subway lines, streets and subway lines. However, one positive that can be taken from the natural disaster is the limited number of casualties.

... longer than those hurricanes that appear in August (Elsner, 2009, p. 61). Generation of hurricanes begins to cool with the cooling of the water in late autumn. At this time, the weather pattern fails to favor the development of tropical development. North Atlantic seasonal cycle pronounces its peak activity during August and September where only 17 percent of activity happens beyond the three months duration of august to October (Elsner, 2009, p. 65). The examination of North Atlantic took into account the mean number of for all hurricanes in a year’s time and for total. North Atlantic experienced hurricanes every season due to the presence of the budget heat and seasonality effects. Budget heat effects influence the hurricanes to occur...

The Events of a Hurricane and the Manner in the Poem Problems with Hurricanes by Victor Hernandes Cruz

...Introduction Problems with Hurricanes by Victor Hernandes Cruz relies on humorous fiction to elucidate a comic impact on the readers, as well as an amalgamation of reality and fiction in an effective way. The utilization of fantasy enables Cruz’s imagination with freedom and thus the realm of reality does not dictate his views and events and thus impossible becomes actuality. The poem revolves around events of a hurricane and the manner in which individuals are more afraid of the falling fruits than natural disasters. Discussion The poet states that a death caused by drowning brings honor rather than passing away as a result of a mango smashing one’s head. By these words, Cruz argues that death by natural causes makes people to feel pity...

As ocean temperatures increase, the intensity and strength of hurricanes also increases

..., were obscure until recently or are still obscure. Some researchers are presently discovering a relationship between the increment in ocean surface temperature and the increment in hurricane intensity and frequency (Chan, 2012). Unless the increment in worldwide temperatures is not stopped or possibly slowed, hurricanes and other natural disasters may tend to keep on growing in duration and strength. It is crucial to see how global warming may incorporate with different variables known to prompt the development of hurricanes (Pielke & Laver, 2005). Anthropogenic components may be in charge of the warming of the globe. Greenhouse gasses discharged through the utilization of agriculture and fossil fuels, and, in addition, numerous different...

Preparation and Response to Hurricanes thunderstorms and winds in excess of 155 miles per hour. In the Northern Hemisphere hurricanes circulate counter-clockwise near the earth’s surface. In the US, all coastal areas along the Atlantic shoreline and the Gulf of New Mexico are prone to hurricanes, and therefore experience heavy rains lasting from June to November. The peak season for hurricanes is from mid-August to late October (FEMA, 2004b). Knowing the seasonality of hurricanes enables the government and the community to prepare for the likelihood of their occurrence. Hurricanes are classified into five categories, for which the disaster preparedness plan should prepare: Source:...
