Lisha. M. . Roubert. University of Wisconsin-Madison. Department of Atmospheric & Oceanic Sciences. Fronts: The Boundaries between Air Masses. A front is defined as the transition zone between two air masses of different density. . Front: a boundary between 2 air masses. Warm air and cold air do not mix well.. Changes in weather occur along fronts.. 4 Types of fronts:. Cold Front. Warm front. Stationary front. Occluded front. 1. Cold Front. 8. th. Grade. Definition. Weather front – The area where two air masses meet and do not mix.. Front and Weather. Different types of fronts produce different patterns of weather. . There are four types of weather fronts:. Lab. Fronts!. Fronts!. What are fronts?. A narrow transition zone, or boundary, between differing synoptic scale air masses whose primary discontinuity is density. Fronts highlight . baroclinic. zones, where temperature advection and atmospheric energy is at work. An . air mass. is a . large . pool of air having similar temperature and moisture . characteristics. . An air mass occupies thousands of square miles of the Earth's surface. Air masses are . created . What’s the difference?. Air Mass. An . air mass . is a large volume of air with the same temperature and moisture content.. As an . air mass . forms, it takes on the characteristics of the area over which it develops.. 1. An air mass is a wide-spread section of the troposphere with uniform . temperature . and . humidity . (moisture). 2. The source region is the geographic location the air mass developed over. . If air settles over one location for a long time, it develops the characteristic temperature and moisture of the area..

Fronts: The Boundaries between Air Masses. A front is defined as the transition zone between two air masses of different density. . & . the weather they bring. Have you ever wondered why we get certain kinds of weather…cloudy days with lots of rain…sudden storms, then cooler weather…?. All weather happens because of the 4 types of fronts & how they interact:. Fronts occur in the boundary zone between polar and tropical air masses.. World War I Aerial Photograph. trenches. trenches. “No man’s land”. Ben Franklin’s Storm. (Nov. 2, 1743). Philadelphia. air masses.. . An . Air Mass. is an immense body of air, some 1600+ km (~1000mi) across and 1-3 km (~.6 to 1.9mi) thick, with relatively homogeneous physical properties (density, T. . and moisture) at a given altitude..
