Unmanned aircraft systems (UASs) provide unique observations not readily available from piloted aircraft or ground- and satellite-based remote sensors. For example, they can reach …
The turbulence temperature spectrum and structure parameter are related through a widely-adopted proportionality coefficient. We formally derive this expression, and present …
The NOAA Warn-on-Forecast System (WoFS) is an experimental rapidly-updating convection-allowing ensemble designed to provide probabilistic operational guidance on high-impact …
During the 2015 Plains Elevated Convection At Night (PECAN) field campaign, several nocturnal low-level jets (NLLJs) were observed with integrated boundary layer profiling systems …
Previous studies have shown that the Weather Research and Forecasting (WRF) model often under-predicts the strength of the Great Plains nocturnal low-level jet (NLLJ), which has …
Nocturnal low level-jets (LLJs) over gently sloping terrain typical of the U.S. Great Plains are investigated by means of direct numerical simulation. Such LLJs develop in a tilted …
This paper describes MicroHH 1.0, a new and open-source (www.microhh.org) computational fluid dynamics code for the simulation of turbulent flows in the atmosphere. It is primarily …
Some 36 years following its creation, the Deardorff 1980 (D80) subgrid turbulence model is perhaps still the most ubiquitous scheme used in large-eddy simulation (LES) studies of …
In many engineering and meteorological applications, atmospheric turbulence within the planetary boundary layer is described in terms of its representative parameters. One such …
An analytical solution of the Boussinesq equations for the motion of a viscous stably stratified fluid driven by a surface thermal forcing with large horizontal gradients (step …
