Weather Variables
Weather Part 3
| Term | Definition |
|---|---|
| Troposphere | The lowest layer portion of the atmosphere where temperature decreases (Weather occurs in this layer only) |
| Stratosphere | A region of the atmosphere where temperature increases |
| Mesosphere | A region of the atmosphere where temperature decreases again |
| Thermosphere | A region of the atmosphere where temperature increases |
| Weather | The present condition of the atmosphere-including temperature, pressure, wind, humidity, and movement (Changes are due mainly to unequal heating of land masses, oceans, and the atmosphere |
| Temperature | The heat energy present in the atmosphere at the location (Influences affecting temperature are solar radiation, angle of insolation, hours of daylight, and reflection off atmosphere) |
| Air-Pressure | The force exerted on a unit of area by the air that exerted equally in every direction (Air is a mixture of gases with molecules that are fast moving and far apart, air pressure increases as you decease your elevation, air pressure decreases as you increa |
| Air Currents | Rising or sinking movement of air perpendicular to the group |
| Wind | The horizontal movement of air parallel to the earth's surface (Wind blows from areas of high pressure to areas of low pressure) |
| Sea Breeze | During the day land heats up faster while water holds its heat, thus creating a low pressure zone over the land (Wind blows from areas of high pressure to areas of low pressure) |
| Land Breese | During the night land cools faster while water holds its heat, thus creating a low pressure zone over the water (Wind blows from areas of high pressure to areas of low pressure) |
| Condensation | The process which gas turns to a liquid |
| R.E.C.C. | Rises - Expands - Cools - Condenses |
| Cloud Formation | Air is warmed from Sun heated surfaces becoming less dense and rising, as it rises it expands and decreases in temperature and pressure, water vapor in the air then condenses as the air is cooled to the dewpoint |
