Weather+Variables

Weather variables are measured using instruments such as thermometers, barometers, psychrometers, precipitation gauges, anemometers, and wind vanes.

Weather patterns become evident when weather variables are observed, measured, and recorded. These variables include air temperature, air pressure, moisture (relative humidity and dew point), precipitation (rain, snow, hail, sleet, etc.), wind speed and direction and cloud cover.

Weather variables are interrelated. For example: temperature and humidity affect air pressure and probability of precipitation air pressure gradient controls wind velocity

Weather variables can be represented in a variety of formats including radar and satellite images, weather maps (including station models, isobars, and fronts), atmospheric cross-sections, and computer models.
