Hurricanes A-level :: essays research papers

     The Caribbean constituent and the South Eastern United States of America are regularly subjected to the extend to of tropical hurricanes(A)     Briefly outline characteristics of such hurricanes.The hurricanes that authorise over the Caribbean neighborhood 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 make believe intense low pressure and strong winds at the earth& group A8217s surface. For their to be enough energy for the hurricane to move, it is essential that there is a considerable source of heat. This is necessary to maintain a consistent egress of rising air in the form of currents. There needs to be a large supply of moisture, as it is necessary for condensation to ram place in order to release potential 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 warmheartedness develops in the centre, in the snapper there is a relative orbit of subsiding pressure. Which is what causes actualize skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds. The hurricanes descend 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 today around a hurricane& antiophthalmic factor8217s &8216eye&8217, which is usually about 32km (20 miles) across, reach more than 300 km/h (190 mph). But in the eye itself seen in the centre of the spi ral-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 primarily to shrubbery, trees, poorly constructed signs, and unanchored sprightly homes. No significant damage to other structures.     Storm surge 1-1.5m above tide. piteous lying coastal roads inundated, minor pier damage, some subtile craft in exposed anchorages torn from moorings.CATEGORY 2     Winds 154-176 Km/hour (83-95 Knots). Considerable damage to shrubbery and tree foliage some trees blown down. Extensive damage to poorly constructed signs. Major damage to exposed mobile home. Some damage to exposed mobile homes. Some damage to cover materials of buildings some window and door damage.
