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.
A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.he thermocline or inversion layer occurs where the temperature profile changes from positive to negative with increasing height. The stability of the night time inversion is usually destroyed soon after sunrise as the sun's energy warms the ground, which warms the air in the inversion layer.
