weather – condition or state of the atmosphere at a given time and place
meteorology – study of the atmosphere and its weather
meteorologist – a person who studies the weather
air mass – large region of the atmosphere where the air has similar properties
throughout
warm front – boundary between air masses that allows a warm air mass to slide up
and over a cold air mass
cold front – boundary where a cold air mass slides under a warm air mass
stationary front – boundary between air masses that are not moving
forecast – prediction about the weather
 Some weather signs can be seen by looking at clouds.
 Changes in wind speed or wind direction can indicate storms or temperature
changes.
 Meteorologists interpret information from a variety of sources and use
those sources to make predictions. The information they use is shown on a
weather map.
 Weather maps may show large masses of warm or cold moving air. Lines
between the air masses are called fronts.
 When a warm front passes over an area, the air temperature increases.
 When a cold front passes over an area, the air temperature decreases.
 Data related to temperature and precipitation can also be found on a
weather map.
