This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...
In this study, the scalar roughness for sensible heat in the temperature profile (z0,h) is determined based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Typically, skin temperatures are inferr ...
Motivated by the observation that the diurnal evolution of sensible and latent heat fluxes tends to maintain a constant Bowen ratio, we derive approximate solutions of the ordinary differential equations of a simplified atmospheric boundary-layer (ABL) mod ...
Heat flux measurements are very important in the study of the atmospheric boundary layer (ABL) dynamics; heat flux controls ABL stability and is therefore crucial to various topics such as air quality and hydrometeorology. Accurate heat flux measurements c ...
[1] A numerical model was developed for the prediction of the density stratification of lakes and reservoirs. It combines a buoyancy-extended k-epsilon model with a seiche excitation and damping model to predict the diffusivity below the surface mixed laye ...
The artificial tracer sulphur hexafluoride (SF6) has been used to study the density-driven deep water exchange between two sill-separated basins of Lake Lucerne, Gersauersee and Urnersee. The sources of the density gradients between the two basins are (1) ...
In this study, we determine the scalar roughness for sensible heat in the temperature profile (z0,h) based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Classically, skin temperatures are infer ...
Large-eddy simulation, with recently developed dynamic subgrid-scale models, is used to study the effect of heterogeneous surface temperature distributions on regional-scale turbulent fluxes in the stable boundary layer (SBL). Simulations are performed of ...
