Ch 11: Hurricanes

Do hurricanes rotate counterclockwise toward surface low or high pressure

low

Between what latitudes are favorable for hurricane development?

5 degrees to 20 degrees latitude

What sea surface temperature creates favorable conditions for development?

warm water greater than 26.5C (80F)

• warm water provides energy for latent heat releaseWhat

What wind/air conditions are favorable for hurricane development

• Light winds

• weak wind shears (tears apart hurricane)

• humid air

• weak trade wind inversion
