Journal ArticleDOI

TL;DR: The Deep Propagating Gravity Wave Experiment (DEEPWAVE) was designed to quantify gravity wave dynamics and effects from orographic and other sources to regions of dissipation at high altitudes as discussed by the authors.
Journal ArticleDOI
The World is Not Flat: Implications for the Global Carbon Balance
TL;DR: In this paper, it is argued that the difference between modeled land surface uptake and this residual is negative, thus suggesting that the different modeling approaches miss an important part in land-atmosphere exchange.
Journal ArticleDOI
The impact of valley geometry on daytime thermally driven flows and vertical transport processes
TL;DR: In this paper, the influence of valley geometry on thermally driven flows is studied by means of high-resolution simulations, where an idealized valley-plain topography and a spatially constant but time-dependent surface sensible heat flux are used to generate upslope, upvalley and plain-to-mountain winds.
Journal ArticleDOI
Airborne Wind Lidar Measurements of Vertical and Horizontal Winds for the Investigation of Orographically Induced Gravity Waves
TL;DR: In this paper, the horizontal wind speed and direction are retrieved from lidar measurements by applying a velocity-azimuth display scan and a spectral accumulation technique, leading to a horizontal resolution of about 9 km along the flight track and a vertical resolution of 100 m, respectively.
Journal ArticleDOI
On the Vertical Exchange of Heat, Mass, and Momentum Over Complex, Mountainous Terrain
Mathias W. Rotach,Alexander Gohm,Moritz N. Lang,Daniel Leukauf,Ivana Stiperski,Johannes Wagner +5 more
TL;DR: The role of the atmospheric boundary layer (ABL) in the atmosphere-climate system is the exchange of heat, mass and momentum between "the earth's surface" and the atmosphere as mentioned in this paper.
