Study Notes
Fronts and Pressure Systems
- The main factor distinguishing a warm front from a cold front on a weather map is the direction of the air mass movement.
- High pressure systems on a weather map are associated with sinking air and fair weather.
Hurricanes
- Hurricanes are directed by the prevailing winds in the upper atmosphere and usually move from east to west.
Measuring Air Pressure
- An instrument called a barometer is used to measure air pressure.
Thunderstorms
- The main cause of thunderstorms is the rapid updrafts of warm, moist air into cold air masses.
Greenhouse Gases
- The primary function of greenhouse gases in the Earth's atmosphere is to trap heat and maintain a habitable climate.
Energy Absorption
- Absorption in the context of the text refers to the process by which the Earth's surface and atmosphere absorb solar radiation.
Radiation
- The type of radiation responsible for influencing the flow of energy between the sun and the Earth's surface is electromagnetic radiation, including visible light and ultraviolet (UV) radiation.
Convection Currents
- The main characteristic of convection currents in the Earth's atmosphere is the circulation of air driven by differences in temperature and density.
Earth's Energy Budget
- The Earth's Energy Budget describes the balance between the amount of solar energy received from the sun and the amount of energy lost to space, maintaining a stable climate.
