Document Summary
Part 3 research: a) trends in temperature time series in the gta: day to day temperature variability and chinooks. Land/sea breezes arise from differential heating of the earth s surface on a daily (diurnal) basis. Land surfaces heats more rapidly and cools more rapidly than water surfaces. During the day, the land surface is typically warmer than the water surface. Warmer air rises and so air is rising over the land and sinking over the water. To complete the circulation air moves from the water area to the land area at the surface. This forms a cool breeze at the surface and is called a sea or lake breeze. It is particularly noticeable during the day in the summer. At the upper level there is a reverse flow with air moving out over the water. At night the opposite occurs, the water surface is warmer than the land. Air rises over the water and sinks over the land.
