Download file to see previous pages Coastal flooding, cyclone, hurricanes, tornado are some of the common coastal storms. Hurricane is generally a tropical cyclone with a wind speed of 74 mph or greater. A tropical cyclone has a wind speed between 39 mph and 73 mph.  Extra tropical cyclone is generally large scale storm of temperate latitudes, while the tropical cyclone which is also called the hurricane is somewhat smaller in area than the former. It is accompanied by high winds and heavy rains. On the other hand tornado or twister is a small but intense storm with very high winds. Generally, it has a limited duration. The thunderstorm is accompanied by brief but heavy rain showers and often by hail. Generally, it is local in nature (“Storm Surge’’).

Storm surge is a high flood of water caused by wind and low pressure which is most commonly associated with hurricanes. It is the most deadly aspect of a hurricane and is responsible for heavy damage during hurricanes. It is different from tidal surges which are violent surges caused exclusively by the tidal shift in sea level.

Storm surge is caused by extremely high winds. This wind pushes the water rapidly and turns it into a huge wave. At the same time, the low pressure caused by the hurricane results in the rise of water level in the lowest-pressure spots and to sink in areas of higher pressure. It exaggerates the wave builds up ("Brendan McGuigan).

In the beginning, a disturbance forms in the atmosphere and develops an area of low atmospheric pressure. Winds begin to move into the center from surrounding areas of higher air pressure. The warm water heats the air and rises as it nears the center. The ocean feeds warmth and moisture into the storm and provides energy that causes the warm air in the center to rise faster. It condenses high and creates thunderstorms. If conditions are favorable, tropical depression develops into a tropical storm and creates a hurricane.
Rising air in the center of the storm condenses and produces heat which forcing it to rise even faster.   ...Download file to see next pagesRead More
