"Wind is an
important factor in climate through its influence on global air circulation
patterns. Climate, in turn, is crucial for determining what kinds of

"How does climate
determine where the earths' major biomes are found?"
The day to day physical
properties of the troposphere, or short-term properties are called weather.
By properties we mean: temperature, pressure, density, humidity,cloud
formation, wind speed and direction, and sunshine or solar radiation.
