How tropical storms develop over warmer water Flashcards
What temperature do tropical storms develop?
Between 5 and 30 degrees north and south of the equator
What temperature does the sea have to be so tropical storms can form?
27 degrees or higher
What is wind sheer?
The difference in wind speed.
When the warm surface water evaporates, rises and condenses into clouds what does it release?
This releases huge amounts of energy, producing powerful storms. This rises air which creates low pressure, which increases surface winds.
Easterly winds near the equator move tropical storms towards where?
the West
As storms move over the ocean, the energy from the warm water does what and what does the wind speed do?
The warm water strengthens the storm and the wind speed increases. Storms lose strength when they move over to land cooler water, because the energy supply from the warm water is cut off.
Why do storms spin?
Because of the Coriolis effect
Where do the majority of storms occur?
The northern hemisphere from August to October, while the Southern hemisphere most storms occur from December to April.
