The water must be at least ____feet deep for a hurricane to form.
What kind of atmosphere is required for latent heat to be released?
What is a low pressure disturbance that is needed for air to converge toward and rise to produce powerful thunderstorms
Easterly wave or tropical wave
A storm can not form 0-5 degrees north or south of the equator because the _______is not strong enough to cause the storm to organize and rotate.
What happens If a storm forms to far north or south of the equator?
It will not produce a hurricane because the water is too cold.
