- 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.
