Hurricanes A-level :: essays research papers

The Caribbean component part and the South Eastern United States of America are regularly subjected to the jounce of tropical hurri masses(A)Briefly outline characteristics of such hurricanes.The hurricanes that run over the Caribbean component part and the United States of America usually eventuate between August and October. For these hurricanes to occur the surrounding ocean temperatures essential be minimal, also there must be a prolonged spell of equable temperature, pressure and humidity in the lower troposphere in conjunction with anti-cyclonic conditions in the upper troposphere. These conditions build intense low pressure and strong winds at the earth&8217s surface. For their to be enough energy for the hurricane to move, it is essential that there is a enormous source of passionateness. This is necessary to maintain a consistent supply of acclivity air in the form of currents. There needs to be a large supply of moisture, as it is necessary for condensation to ta ke family in order to release latent heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall.When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsidence pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in hitch warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds. The hurricanes decline as soon as the source of heat is lost/or removed. Although it can take between 9 and 15 days for this to happen. Winds immediately nigh a hurricane&8217s &8216eye&8217, which is usually about 32km (20 miles) across, reach to a greater extent than 300 km/h (190 mph). But in the eye itself seen in the centre of the spiral-the weather is clear and calm. (B)Identify the various types of damage caused by the passage of these hurricanesCATEGORY 1 Winds 118-152 Km/hour (64-82 Knots). Damage mainly to shrubbery, points, poorly constructed signs, and unanchored prompt homes. No significant damage to other structures. beleaguer surge 1-1.5m above tide. Low lying coastal roads inundated, forgivable pier damage, some small craft in exposed anchorages lacerated from moorings.CATEGORY 2Winds 154-176 Km/hour (83-95 Knots). Considerable damage to shrubbery and tree foliage some trees blown down. Extensive damage to poorly constructed signs. study damage to exposed mobile home. Some damage to exposed mobile homes. Some damage to roofing materials of buildings some window and door damage.
