SEA BREEZE
CHARACTERISTICS
(You should know and be able to
explain these characteristics)
1. Strongest at shoreline.
2. Can extend more than 12 miles inland (penetration depends somewhat on local topography).
3. Can extend to heights greater than 300 meters ~ 1000 feet (but often is shallower).
4. Much stronger than land breeze (because ΔT, temperature differential, is greater during the day
than at night).5. Strongest when and where ΔT is greatest (in the tropics and in mid-latitudes during spring and
early summer).6. Breeze front generally reaches the beach before noon and migrates inland as the afternoon passes.
7. Turns off around sunset.
8. Breeze front is hazy if the relatively humidity exceeds 70% (smoggy if the area is polluted) and
becomes foggy as RH approaches 100%.9. Often, in convergence zone, produces cumulus clouds (usually low) over land during the daytime
(especially over peninsulas). (The land breeze may produce cumulus clouds over water at night).10. A similar "lake breeze" may occur along the shoreline of a large lake.
