METEOROLOGY
|
The science that deals with the phenomena of the atmosphere, especially weather and weather conditions.
|
|
|
METEOROLOGIST
|
One who studies meteorology.
One who reports and forecasts weather conditions |
|
|
TROPOSPHERE
|
The lowest region of the atmosphere between the earth's surface and the tropopause, characterized by decreasing temperature with increasing altitude.
|
|
|
STRATOSPHERE
|
The region of the atmosphere above the troposphere and below the mesosphere.
|
|
|
MESOSPHERE
|
The portion of the atmosphere from about 30 to 80 kilometers (20 to 50 miles) above the earth's surface, characterized by temperatures that decrease from 10°C to -90°C (50°F to -130°F) with increasing altitude.
|
|
|
THERMOSPHERE
|
The outermost shell of the atmosphere, between the mesosphere and outer space, where temperatures increase steadily with altitude.
|
|
|
BAROMETER
|
An instrument for measuring atmospheric pressure, used especially in weather forecasting.
|
|
|
THERMOMETER
|
An instrument for measuring temperature, especially one having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.
|
|
|
DEW POINT
|
The temperature at which air becomes saturated and produces dew.
|
|
|
RELATIVE HUMIDITY
|
The ratio of the amount of water vapor in the air at a specific temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage.
|
|
|
PSYCHROMETER
|
An instrument that uses the difference in readings between two thermometers, one having a wet bulb and the other having a dry bulb, to measure the moisture content or relative humidity of air.
