Examples of Temperature inversion in a sentence

  • Temperature inversion strength was interpreted from data from the BCM met tower, located near the administration area, which has temperature sensors at 2m and 52m above ground level.

  • Temperature inversion occurs in the surface layer of the atmosphere, especially from the ground, as well as in the free atmosphere, especially at the its lower two-kilometer layer.

  • Temperature inversion heights are especially low during the cold seasons of the year, frequently being lower that the surrounding hills and comparable to the heights of the highest chimneys characteristics of the large industrial compounds in the area.
