MET - Local Winds

What causes a sea breeze?

• The high pressure at surface over the land and low over the sea

• Higher pressure aloft over the sea causing transfer of mass

• The land warming quicker than the sea

• Pressure lapse rate being greater over the land than sea

What is sea breeze caused by?

• The transfer of air mass aloft causes a comparatively higher pressure over the sea

• The sun heating the sea more than the land

• A high pressure created over the sea aloft, transferring to the land

• The cooling of air at sunset, creating a high pressure over the land

Which is correct in regards to the strength of the sea breeze?

• it is 20 - 30kts

• depends on the slope between the land and sea

• depends on the pressure lapse rate between the land and sea
