Evolution of the Nocturnal Inversion Layer at an Urban and Nonurban Location

摘要

The evolutionary cycle of the nocturnal radiation inversion layer from formation until dissipation under fair weather conditions was investigated by time-series analyses of observations of inversion base and top heights, and inversion strength at an urban and a nonurban site in St. Louis, Missouri. The time-dependent behavior of each inversion parameter is presented from statistical and least-squares regression analyses. Differences of inversion evolution between these sites are discussed.
