Weather

Weather is a set of all the things happening in a given atmosphere at a given time. The atmosphere is the air mass that surrounds the earth. The energy from sun, or solar energy, is what causes weather. Weather is caused by the uneven heating of the atmosphere. Weather phenomena happen in the troposphere.

The troposphere is the area of the atmosphere that is the closest to the surface of the earth. Weather refers to day-to-day temperature and precipitation. Climate refers to the average atmospheric conditions for a long period of time.

The part of atmosphere that affects the transmission of radio waves is the ionosphere. The stratosphere is the area of the atmosphere that is above the troposphere.

The mesosphere is on top of the stratosphere. A front is the line where air masses meet. The greenhouse effect occurs when air above earth is warmed by the reflection of the sun and is prevented from going back into space.

Convection is the transfer of heat by air or water. The trade winds are a system of winds that come from the north and south rushing to the warm air found on the equator.
