Title :

Pollutant dispersion modelling on a local to regional scale around Cadarache (South-East of France): the influence of orography and stability

 

Summary:

The winter field measurement campaign KASCADE has revealed that under weak synoptic forcing the Cadarache-site, in South-eastern France, is subjected to flows of different sizes, related to the orography and local meteorological phenomena. The purpose of the thesis work is to validate and optimize the modeling of atmospheric pollutant release dispersion over Cadarache. This will be achieved by mean of mesoscale numerical weather prediction code WRF (used with a kilometric resolution up to hectometric resolution) associated with the lagrangian dispersion code FLEXPART.  The work will be focused on :

•Effect of the Durance and Verdon valleys and pre-alp orography

•Vertical structure of the flow (inversion gradient, exploring the appearance of many inversion layers, low level jet)

•Diurnal evolution of the wind : stable drainage flows, sea breeze or anabatic flows, synoptic flows

•Seasonal effect on the flows. KASCADE campaign for winter, ESCOMPTE campaign for summer, are available in addition to routine measurements.

•Subgrid effect of non-resolved orography by using high-resolution WRF experiments (100m)

•Effect of Landuse on turbulence, evaporation, diurnal temperature range.
