By THOMAS BEAUMONT for the Des Moines Register, May 31, 2008 Two of the three Republican candidates for U.S. Senate in Iowa had differing outlooks Friday on how to solve the federal immigration problem as they debated issues before Tuesday's primary election.
Temperature inversion layers, also called thermal inversions or just inversion layers, are areas where the normal decrease in air temperature with increasing altitude is reversed and air above the ground is warmer than the air below it.his is why inversion layers are called stable air masses. Temperature inversions are a result of other weather conditions in an area. They occur most often when a warm, less dense air mass moves over a dense, cold air mass.
Temperature inversions usually form near the boundaries of warm and cold air that define fronts. While most fronts do create inversions, they are most pronounced in warm fronts. These inversions are known as frontal inversions. They form near the warm-cold air boundaries as warm air overruns colder air at the surface.
