How do hurricanes weaken and dissipate?
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.

High wind shear
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'…s over warm water, the storm can continue to replenish itself; but as soon as it hits cooler water or dry land, things start to fall apart. The center of circulation weakens, and pretty soon all you have left is a regular rainstorm: what meteorologists call a remnant low. That tropical remnant can travel hundreds or thousands of miles in just a few days, until it runs out of energy (usually in the high northern latitudes) and disperses completely. Hurricanes die over land because they depend on evaporation from warm ocean water to maintain their strength. When they move over land they are cut off from this energy source.
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.… That is a small and simple reason. a hurricane must have a heat of at least 80 F or 26.5 C.
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 …hurricane. This source of energy is lost on land and the storm dumps its water on the land as it cools.
What does it mean when a hurricane is dissipated?
it basically means the hurricane has ended
When do hurricanes weaken?
Hurricanes weaken either when they move over land or colder water.

How do hurricanes weaken?
Hurricanes weaken when they are not over warm water or are over cooler water. (You couldn't have a hurricane in an area that is not near warm water). When they come to land th…e energy from the wind is lessened by the land formations as both land and cold water cut off a hurricane from the warm water the provides its energy.

How did Hurricane Katrina dissipate?
Hurricane Katrina stopped because when she reached the land she didn't have any water or power source!

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 …energy from the ocean in that area. Hurricanes help regulate the Earth's temperature and if an area has already been "regulated" then there would be less energy to feed the system.

What are the three factors that weaken a hurricane during development?
Many factors may cause the development of a hurricane to weaken. Three factors are low sea surface temperature, high wind shear and making landfall.
