URGENT: Why the intensity of a tropical cyclone will reduce after it makes landfall?

Question

And does the same theory apply to waterspouts?

Answer 1

Good question. Two quick scientific explanations - the heat from which the storm draws its energy is the ocean surface. So this has evaporated (excuse the pun). Secondly, friction begins to slow the winds down, coriolis decreases as a result, and the winds rush down the pressure gradient towards the center of circulation eliminating the pressure gradient and the storm's circulation. Ok?

Answer 2

Water cyclones and water spouts weaken once they hit land. A tropical cyclone feeds on the heat released when moist air rises and the water vapor condenses. The adjective "tropical" refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in tropical, or more precisely, 'maritime tropical' air masses. Hurricanes and waterspouts will weaken rapidly when they travel over land or colder ocean waters -- locations with insufficient heat and/or moisture. Most strong storms lose their strength very rapidly after landfall and become disorganized areas of low pressure within a day or two, or evolve into extratropical cyclones. There is a chance they could regenerate if they manage to get back over open warm water. If a storm is over mountains for even a short time, it can rapidly lose its structure. Many storm fatalities occur in mountainous terrain, as the dying storm unleashes torrential rainfall which can lead to deadly floods and mudslides.[citation needed] Additionally, dissipation can occur if a storm remains in the same area of ocean for too long, mixing the upper 100 feet (30 meters) of water, which draws up colder water due to upwelling and becomes too cool to support the storm. Without warm surface water, the storm cannot survive.
A tropical cyclone can dissipate when it moves over waters significantly below 26°C. This will cause the storm to lose its tropical characteristics (i.e. thunderstorms near the center and warm core) and become a remnant low pressure area, which can persist for several days. This is the main dissipation mechanism in the Northeast Pacific ocean. Weakening or dissipation can occur if it experiences vertical wind shear, causing the convection and heat engine to move away from the center which normally ceases development of a tropical cyclone. This process can take 3-5 days. Even after a tropical cyclone is said to be extratropical or dissipated, it can still have tropical storm force (or occasionally hurricane force) winds and drop several inches of rainfall. In the Pacific ocean and Atlantic ocean, such tropical-derived cyclones of higher latitudes can be violent and may occasionally remain at hurricane-force wind speeds when they reach the west coast of North America or Europe, where they are known as European windstorms. The extratropical remnants of Hurricane Iris in 1995 became such a windstorm.
A hurricane can weaken if an outer eye wall forms (typically around 50-100 miles from the center of the storm), choking off the convection within the inner eye wall. Such weakening is generally temporary unless it meets other conditions above. Additionally, a cyclone can merge with another area of low pressure, becoming a larger area of low pressure. This can strengthen the resultant system, although it may no longer be a tropical cyclone.

Answer 3

Short answer: warm water is a hurricane's fuel. It literally begins running out of gas upon being completely over land.

Waterspouts are almost like baby tornados, and although I don't honestly know if the same applies, my guess would be yes, because I have watched many of them quickly fall apart within a few hundred yards of being on land.

Answer 4

They are fed by warm water. As soon as they make landfall they lose their power source.

Answer 5

the energy is transfered over the ground. over ground would make it a tornado. winds travel better over water too.

Answer 6

a tropical cyclone is worse over the sea, then when it hits ground its force is greatly diminished, probably due to increased friction when compared to water.

i dont know about watersprouts.
