SEA AND LAND BREEZES
LEARNING TO FORECAST IN FLORIDA DURING JULY

- Pressure starts out equal but due to unequal surface heating, the thickness over the land (sea at night) is greater.

- An upper-level high develops over the land creating divergence and a subsequent drop in surface pressure.

- Air begins rising and is coupled with low-level convergence.

- The circulation completes its loop and water-laden air rises, cools and produces condensation and clouds.

- Thunderstorms may develop if atmospheric instability is enhanced by surface heating.

- Sea breezes occur mid to late afternoon when land-sea temperatures differences are greatest.

- In early pre-dawn hours, a reverse circulation may be induced, known as a land breeze.
