Hurricanes depend on a continuous supply of moisture from warm ocean water to maintain themselves. If the storm moves over land or cold water it loses this fuel source and weakens. This can also happens of the hurricane moves into a mass of dry air. Additionally, if a hurricane encounters strong wind shear it can be essentially ripped apart.
Detailed Answer:
A tropical cyclone can cease to have tropical characteristics through several different ways. One such way is if it moves over land, thus depriving it of the warm water it needs to power itself, quickly losing strength. 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. While there is a chance a tropical cyclone could regenerate if it managed to get back over open warm water, if it remains over mountains for even a short time, weakening will accelerate. Many storm fatalities occur in mountainous terrain, as the dying storm unleashes torrential rainfall, leading to deadly floods and mudslides, similar to those that happened with Hurricane Mitch in 1998. additionally, dissipation can occur if a storm remains in the same area of ocean for too long, mixing the upper 60 metres (200 ft) of water, dropping sea surface temperatures more than 5 °C (9 °F). Without warm surface water, the storm cannot survive.

What causes a hurricane to weaken when it hits land?

The primary reason for the loss of wind speed is that the hurricane has been cut off from its power supply: the heat provided by the convection of water at its core. While it'

Why does a hurricane weaken over land?

due to specific heat the air over land will cool quickly causing the hurricane to slow down and weaken. That is also on of the main reasons a hurricane can not form over land.

Why do the hurricanes weaken as they move over land?

Hurricanes gain their strength from the heat contained in the warm tropical waters over which they pass. The heat of the sea is passed to the air and water vapour forming the

When do hurricanes weaken?

What is dissipate?

If there are two hurricanes right after another in the same path does one weaken?

    It is possible that a hurricane following the same path as another tropical system could weaken, because the first tropical system would have absorbed much of the
