Best Answer: Because water heats and cools much slower than air, these large bodies of water have a moderating effect on land temperatures. In spring, when air temps over land are getting warmer, the body of water, which stays cooler much longer, cools the air immediately surrounding it. Likewise, in fall and winter, when cold air spreads over the land mass, these bodies of water retain their warmth, preventing temps from getting as cold around them. That is the effect that lakes have on land temperatures. The prevailing winds are also a large factor. Oceans provide land and sea breezes.
Therefore, the air pressure is lower. Air temperature changes as you go higher above the earth. Since the surface of the earth heats the air above it, the air is warmer near the ground. Air pressure on the earth's surface also changes. Changes in temperature cause changes in air pressure. As the air near the surface of the earth becomes warmer, the particles becomes warmer, the the particles of the air move farther apart. The air becomes lighter and rises. The lighter air pushes down on the surface of the earth with less pressure.
