The sea breeze flows from the cool sea to the warm land during the day and is caused by the temperature difference between the two surfaces. The convergence of winds near the sea breeze boundary causes air to rise, sometimes triggering the formation of clouds along the front. The first figure
shows an example of the development and progression of the cloud line depicting the sea breeze front along the coastline of Columbia during the day for 29 April, 1997 (1715-2015 GMT).
Satellite cloud climatologies can help show how persistent a feature such as the sea breeze is. The second figure shows 16-day average images for the same time periods at the end of January. Although not as distinct as an individual day, the sea breeze front is discernable. The third figure shows deeper convective development along the sea breeze front, particularly by
2015 GMT (1 May 1997).
Ken Gould, NWS, Tallahasse, Florida, has been working with sea breeze satellite cloud climatologies for the past 2 summers and will continue this summer. Perhaps Ken can share some insights and results as the season starts.
