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.
The mesosphere (/ËmÉsoÊsfÉªÉr/ ; from Greek mesos middle and sphaira ball) is the layer of the Earth's atmosphere that is directly above the stratopause and directly below the mesopause. In the mesosphere temperature decreases as the altitude increases.octilucent clouds are located in the mesosphere. The upper mesosphere is also the region of the ionosphere known as the D layer. The D layer is only present during the day, when some ionization occurs with nitric oxide being ionized by Lyman series-alpha hydrogen radiation.
