Downslope Windstorms in the Lee of Ridges on Mars

Icarus, 1995
Abstract The semianalytical theory of downslope windstorms, originally developed to understand large increases in surface winds in the lee of major mountain chains on Earth, such as the famous windstorms in Boulder, Colorado, is applied to martian conditions.

Statistical Modeling of Downslope Windstorms in Boulder, Colorado

Weather and Forecasting, 2008
Abstract Downslope windstorms are of major concern to those living in and around Boulder, Colorado, often striking with little warning, occasionally bringing clear-air wind gusts of 35–50 m s−1 or higher, and producing widespread damage.

Effects of Inversion Height and Surface Heat Flux on Downslope Windstorms

Monthly Weather Review, 2011
Abstract Simulations are presented focusing on the role of temperature inversions in controlling the formation and strength of downslope wind storms. Three mechanisms are examined depending on the relative height of the inversion with respect to the mountain and the stability of vertically propagating mountain waves.

Numerical Simulation of Wave Drag during Downslope Windstorms in Different Regions of Russia

Russian Meteorology and Hydrology, 2018
The wave drag is considered for downslope windstorms in Novorossiysk, on Novaya Zemlya, and in Pevek. The research is based on the results of numerical simulation with the WRF-ARW model. Special attention is paid to the evaluation of the contribution that wave processes make to the overall dynamics of the phenomenon (based on the ratio of wave and ...

A review of the evidence for strong, small-scale vortical flows during downslope windstorms

Journal of Wind Engineering and Industrial Aerodynamics, 1990
Abstract During downslope windstroms, damage can occur on quite small scales. In the foothills near Boulder, Colorado, individual trees or lines of trees may be uprooted or snapped off with little or no damage to surrounding vegetation. Also, considerable damage can occur to individual structures with no primary damage occurring nearby.

Pulsating Downslope Windstorms

Journal of the Atmospheric Sciences, 1989
Abstract The flow configurations that obtain in several severe downslope windstorm events generated over isolated topography are studied using a two-dimensional nonlinear anelastic model. A new high resolution simulation of the 11 January 1972 windstorm in Boulder, Colorado, constructed using a very large model domain, is shown to qualitatively ...

The bimodal downslope windstorms at Kvísker

Meteorology and Atmospheric Physics, 2010
Downslope windstorms at Kvisker in Southeast Iceland are explored using a mesoscale model, observations and numerical analysis of the atmosphere. Two different types of gravity-wave induced windstorms are identified. At the surface, their main difference is in the horizontal extent of the lee-side accelerated flow.

The Origin of Severe Downslope Windstorm Pulsations

Journal of the Atmospheric Sciences, 1990
Abstract Recently reported Doppler lidar observations of the downslope component of flow velocity made during the occurrence of a mountain windstorm at Boulder, Colorado, have established that such storms are characterized by an intense pulsation of windspeed with characteristic period(s) near 10 minutes.
