Question

20) Name 3 things that will cause a hurricane to weaken and maybe fall apart?

Answer 1

Answer:

1. Interaction with land
2. Conctact with colder water
3. Strong vertical wind shear

Explanation:

1. The interaction with land: a hurricane needs evaporation from the ocean surface to survive, when it touches land the hurricane is separated from its energy source since the air masses over the ocean are drier, less moisture is carried into the storm and air is cooled and then sinks disrupting hurricane's circulation.
2. Getting in contact with colder water: when a hurricane moves northward out of the tropical ocean into mid-latitudes, it begins to get in contact with colder water, this makes it lose the warm water source, less moisture is evaporated into the atmosphere to supply clouds and this weakens the storm.
3. Strong vertical wind shear: a change in wind direction or speed with height can enhance the mixing of drier environmental air into the storm eyewall leading to a column of cool air that rapidly sinks into the grounds, this inhibits the intensification of the hurricane. This kind of wind shear can be generated by fast upper-tropospheric winds.
