What is weather?? BY: MIRANDA JO ANDERSON
Atmosphere The atmospheric factors that interact to cause weather are heat energy air pressure, winds, and moisture.
The sun’s energy that is absorbed by the Earth is spread throughout the atmosphere in three basic ways: conduction, convection, and radiation.
Conduction The direct transfer of heat energy from one substance to another.
Convection The transfer of heat energy in a fluid (gas or liquid). Air is a fluid.
Radiation Is the transfer of energy by waves such as light.
Greenhouse effect The gases act like the glass in a greenhouse to trap heat. The greenhouse makes the Earth a comfortable place to live.
Air Pressure The air pressure at any particular point on the Earth depends on the density of the air. (Density is equal to mass divided by volume).
Barometer Measures the air pressure on the Earth.
Winds Formed by movement of air from one place to another
Both local winds and global winds are caused by differences in air pressure due to unequal heating of the atmosphere
Coriolis effect A Coriolis effect is the apparent shift in the path of any fluid or object moving above the surface of the Earth due to the rotation of the Earth.
Anemometer Used to measure wind speed
