weather fronts
Air mass meetings
Weather fronts are boundaries between air masses of different temperatures or humidity levels.
When these masses meet, the denser cold air pushes under warmer air or warm air rides over cold, producing the cloud formations and precipitation associated with changing weather.
Meteorologists track cold fronts, warm fronts, and stationary fronts to forecast storms: A cold front is moving through tonight.
