TALLAHASSEE, Fl. (WTXL) -- Every Tuesday on WTXL Sunrise, you'll be able to have one of your own weather questions answered by Meteorologist Alex Cordero.

This week, our question was sent in from Jordan Rains via Facebook.

He asks: What is the Sea Breeze? How does it form?

The Sea Breeze Circulation involves the flow of cooler air over the ocean surface toward warmer air over land.

To start, surface temperatures over water are cool. This forms a small area of high pressure. The cool air is dense. Warmer temperatures over land are warmer.

This air isn't as dense as the cooler air, so it rises, forming low pressure. The dense and cool air moves toward the less dense, warm air over land. 

As the cool, dense air moves toward the coast, it helps to raise the warm, less dense air over land. The warm air will condense as it rises. This can form clouds and storms. 

It is essentially a small cool front that extends across the coast and can push inland.

Above the warm low, as winds rise, high pressure forms aloft. Above the cool high, the sinking air comes from low pressure aloft. Together, these four systems form a circulation.

When the sun sets, the temperature flux reverses, which can form a weaker land breeze mechanism.
