METEOROLOGIST

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.
