Dissipation In Hurricanes

When a hurricane strikes, it is followed by a number of serious dangers which include heavy rains, high winds, a storm pour, and even tornadoes. The main objective of this page is dissipation in hurricanes and their dispersion. Read on.


Several different ways are the cause for the disintegration of hurricanes. One such way is if the cyclone moves over land, it is deprived of the warm water needed to power itself. Thus it quickly loses its strength. Most dispersion of hurricanes comes quickly after the loss of their strength very rapidly after landfall. They either evolve into extra tropical cyclones or become unsystematic areas of low pressure within a day or two. If it remains over mountains for even a short time, dissipation in hurricanes will continue and weakening will speed up.



It has been seen that most storm fatalities happen in the mountainous landscape. As the dying storm sets free heavy rainfall, it leads to deadly floods and mudslides. Additional disintegration of hurricanes can happen if a storm remains for too long in the same area of ocean. But in the absence of warm surface water, the storm cannot survive.


Dissipation in hurricanes or tropical cyclone can also occur when it moves over waters significantly below 26.5 °C , for this will cause the storm to lose its tropical personality and become a residual low pressure area, persisting for several days. This is the main dissipation mechanism in hurricanes in the Northeast Pacific ocean.

Disintegration of hurricanes can also happen if it faces a vertical wind shear. This results in the convection and heat engine to move away from the center and thus cease the development of a tropical hurricane. Additionally, a cyclone can combine with another area of low pressure, and thus becoming a larger area of low pressure. Although this can reinforce the resultant system, it may no longer be a tropical cyclone. Recent studies in have given rise to the hypothesis that great amounts of dust weaken the power of tropical hurricanes.


Several attempts have been made in the past by countries to weaken hurricanes to induce artificial dissipation in hurricanes. This is done by sowing selected storms with silver iodide through Project Stormfury. The seeding is supposed to form super cooled water in the outer rain bands to freeze, and thus resulting the inner eyewall to collapse. This helps in reducing the power of the thus reducing the winds. Other approaches have also been proposed over time, which include cooling the water under a tropical cyclone by towing icebergs into the tropical oceans. But tropical hurricanes are simply too huge and short-lived for any of the weakening techniques to be practical for disintegration of hurricanes.
