Special Issue on Characteristics of Downslope Windstorms for Engineering Applications
Wind and structures, 2017Activities in the field of wind engineering include social and economic impacts of wind effects, wind characteristics, local wind environments, wind loads and structural response, diffusion, pollutant dispersion and matter transport, wind effects on building heat loss and ventilation, wind effects on transport systems, wind power generation, and ...

The eastern Adriatic coast, roughly N Mediterranean, is well known for Bora wind - a gusty downslope windstorm which typically blows from the NE quadrant with sustained wind speeds between 5-20 ms^-1, its gusts surpassing 50-70 ms^-1 in the lee of the coastal mountains.

Multiscale simulations of bora downslope windstorm events
2019Bora events over the eastern Adriatic coast are well known for exceptional spatial and temporal wind variability. Such a wind climate is a challenge for wind studies which require knowledge of wind conditions in a relatively small area (e.g. 10 km x 10 km).

Downslope Windstorms. Part I: Effect of Air Density Decrease with Height
Journal of the Atmospheric Sciences, 1991Abstract In 1985 Smith published a solution of a nonlinear, steady-state, two-dimensional, mesoscale problem concerning airflow crossing a mountain ridge. He used his solution to explain the mechanism of severe downslope winds. In particular, Smith considered the 11 January 1972 windstorm in Boulder, when an undisturbed flow approaching the ridge ...

Model representation of a downslope windstorm in north-west Iceland
2023The role of turbulent exchange of heat and moisture in the lee of mountains is not well understood, and these processes are generally not resolved or parametrised in numerical weather prediction (NWP) models. High resolution Met Office Unified Model (MetUM) simulations are run and compared to in-situ observations from 12th and 19th March 2018 over ...

Analysis and predictability of the 1 December 2011 Wasatch downslope windstorm
2014A downslope windstorm on 1 December 2011 led to considerable damage along a narrow 50-km swath at the western base of the Wasatch Mountains in northern Utah. Operational forecasts issued by the Salt Lake City National Weather Service Forecast Office provided accurate guidance for the event at lead times of 1-2 days, based in part on their locally ...

A review of the evidence for strong, small-scale vortical flows during downslope windstorms
Journal of Wind Engineering and Industrial Aerodynamics, 1990Abstract 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.

Numerical Simulation of Wave Drag during Downslope Windstorms in Different Regions of Russia
Russian Meteorology and Hydrology, 2018The 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 ...

Downslope windstorms over very complex orography: formation and development of pulsations
2013While severe northern-Adriatic downslope windstorms are since long in the focus of interest, strong bora winds in the hinterland of mid-Adriatic coast are much less studied, yet frequent and eqaully severe phenomena. The predictability of these events is considerably lower than for its northern counterpart due to the inflow complexity induced by the ...
