Daily cycle of atmospheric boundary layer in different soil moisture conditions
Neumanová, Kateřina ; Sedlák, Pavel
In the case of wet soil the turbulent flux of latent heat from the surface is larger and the daytime convective boundary layer is much shallower. At night the surface cooling rate is lower and the surface temperature inversion is weaker.
Role of local factors in formation and development of radiation fog
Potužníková, Kateřina
At the Institute of Atmospheric Physics in Prague, the 1-D atmospheric boundary layer (ABL) model has been designed to study the development of ABL structure. The model parameterisations include the atmospheric radiative transfer, the condensation process and the soil-vegetation-atmospheretransfer so that the model is able to predict the occurrence and evolution of radiation fog. The fog formation, development and dissipation are strongly influenced by local factors, such as soil and vegetation characteristics (albedo, moisture, heat conductivity, and especially vegetation height and coverage). Model simulations of the impact of different vegetation covering, soil moisture, occurrence of middle clouds and wind velocity on the ABL state and on the life cycle of radiation fog is presented.
