Analytical consideration of the influence of evaporation and moisture on daytime convective boundary layer evolution

Popis výsledku v původním jazyce

The aim of this study is to obtain a through understanding of the growth of the convective boundary layer with the influence of atmospheric humidity. The bulk mixed layer model is numerically analyzed to determine the development of the convective boundary layer with and without taking into consideration the influence of moisture content. Several modified simulations are proposed with the replacement of the kinematic virtual potential temperature (buoyancy) flux, and virtual potential temperature, intothe calculation steps. The simulation results increase satisfactorily, and show good agreement with the theoretical evolution of the tropical mixing height. All simulations taking into account moisture content give significant values that are higher thanthose that neglect moisture content.The obtained Bowen ratio values range from 0.4 < B < 0.6 over the moist surface indicates that surface evaporation plays an important role in convective mixing processes
