An onshore wind is any wind that blows from a body of water toward land. An offshore wind is any wind that blows from the land toward body of water.
Explanation:
The onshore winds are winds that form over larger bodies of water.
These winds move from the body of water toward the land, usually during the day.
The reason for that is that the bodies of water have lower temperature during the day, so the air above them is cooler, denser, so it moves toward the less dense, warmer air over the land.
The offshore winds are winds that form over land.
These winds move from the land toward a body of water, usually during the night.
The land heats up faster than the water, but also cools off quicker than the water, so at night the land is cooler. Because of it, the air masses that form over the land are more dense, so they move toward the less dense air masses over the water bodies.
<u>Inversion is found in upper layer sf troposphere.</u>
Explanation:
When there is a decrease temperature t every 3.5 degrees for every 100 feet. As when this normal cycle is present the air said to be unstable and constantly flows between the warm and cold areas.
During inversion temperature decrease with the increasing altitudes. temperature inversion can occur in areas of coastal origins due to the upwelling of cold waters.
Topography plays a role as cold and cool air flows from the mountain peaks down into valleys. This cold air then is pushed back due to the warm and lighter air mass and hence creating an invention.
Inversions can also form in areas with significant snow cover as the ground is cold white color reflects most of the sunlight.
