On the Wind and Turbulence in the Lower Atmosphere above Complex Terrain
Numerical Modeling Complex Terrain Characteristics of Atmospheric Turbulence
2013/3/6
Numerical modeling and studies of the wind fields at the junction of three continents: over the complex terrains of the South-east Europe, Asia Minor, Middle East, Caucasus and over the Black, Caspian...
Mediterranean offshore extreme wind analysis from the 44-year HIPOCAS database: different approaches towards the estimation of return periods and levels of extreme values
wind extreme values
2010/1/27
The present contribution addresses the performance of a statistical extreme wind analysis over the whole Mediterranean Basin. Estimations of return periods and levels are obtained over offshore areas ...
The relationship between heavy rain (HR) and/or strong wind (SW) events and cyclones is investigated for the Balearic Islands. First, a list of HR and SW events is cross-referenced with an objective c...
The interaction of northern wind flow with the complex topography of Crete Island–Part 1:Observational study
northern wind flow complex topography Crete Island Observational study
2009/12/10
The island of Crete with its mountain ranges is an excellent example of a major isolated topographic feature, which significantly modifies the regional airflow as well as the pressure and temperature ...
Snow fences on slopes at high wind speed: physical modelling in the CSTB cold wind tunnel
Snow fences high wind speed physical modelling the CSTB cold wind tunnel
2009/12/9
In order to determine the effect of steep slopes on snowdrift generated by snow fences, we have conducted physical modeling experiments in the CSTB (Centre Scientifique et Technique du Bâtiment)...
Effect of unsteady wind on drifting snow: first investigations
Drifting snow blowing snow gust blast acoustic sensor
2009/12/9
Wind is not always a steady flow. It can oscillate, producing blasts. However, most of the current numerical models of drifting snow are constrained by one major assumption: forcing winds are steady a...
Quantifying changes of wind speed distributions in the historical record of Atlantic tropical cyclones
Quantifying changes wind speed distributions historical record Atlantic tropical cyclones
2009/12/8
Here we re-examine the official Atlantic basin tropical cyclone (hurricane) database HURDAT (1851–2008) and quantify differences between wind speed distributions in the early historical (1851–1943) re...
The interaction of northern wind flow with the complex topography of Crete Island – Part 1: Observational study
northern wind the complex topography Crete Island Observational study
2009/12/31
The island of Crete with its mountain ranges is an excellent example of a major isolated topographic feature, which significantly modifies the regional airflow as well as the pressure and temperature ...
Turbulent wind waves on a water current
Turbulent wind waves water current gravitation force
2010/1/28
An analytical model of water waves generated by the wind over the water surface is presented. A simple modeling method of wind waves is described based on waves lengths diagram, azimuthal hodograph of...
Optics and remote sensing of Bahamian carbonate sediment whitings and potential relationship to wind-driven Langmuir circulation
remote sensing Bahamian carbonate sediment whitings wind-driven Langmuir circulation
2010/1/19
Regions of milky white seas or "whitings" periodically occur to the west of Andros Island along the Great Bahama Bank where the bottom sediment consists of fine-grained aragonite mud. We present measu...
Wind Shifts May Stir CO2 From Antarctic Depths--Releases May Have Speeded End of Last Ice Age—And Could Act Again（图）
Wind Shifts CO2 Antarctic Depths Last Ice Age
2009/12/10
Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age--and could be repeated as manmade warming pr...
Climate change impact of wind energy availability in the Eastern Mediterranean using the regional climate model PRECIS
Climate change impact wind energy availability Eastern Mediterranean regional climate model PRECIS
2010/1/4
Global near-surface wind fields are projected to change as a result of climate change. An enhanced knowledge of the changes in wind energy availability in the twenty-first century is essential for imp...
Evaluation of the CPTEC/AGCM wind forecasts during the hurricane Catarina occurrence
CPTEC/AGCM wind forecasts hurricane Catarina occurrence
2010/1/27
In March 2004 occurred the first hurricane registered at South Atlantic Ocean. The system named Catarina begun as an extratropical cyclone and remained quasi-stationary some days over the South Atlant...
Dependence of CO2 advection patterns on wind direction on a gentle forested slope
Dependence CO2 advection patterns wind direction gentle forested slope
2010/1/15
Gravitational flows generated on a gentle slope in stable conditions were analysed at a forested site at Vielsalm in Belgium. There were two distinct situations at the site, one corresponding to verti...
