Air Masses are named based on where they FORMED…. Forecasting Weather. Now that Meteorologists understand the factors that affect weather they must put all of this together to create . weather maps. and to determine . weather patterns. .. Together weather maps and weather patterns are very helpful in . 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.. Connecting the Weather. Air Masses. Fronts. Jet Stream. Quiz. Midweek Seminars.

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:. Air masses. A body of air with similar characteristics throughout. Humidity. . and . temperature. are the two main characteristics used to classify air masses.. The “first name” of an air mass describes the humidity of the air mass..
