Global Climate Modeling
|Coordinator||Stockholms universitet - Meteorologiska institutionen|
|Funding from Vinnova||SEK 3 000 000|
|Project duration||January 2008 - June 2012|
Purpose and goal
This project aims at improved understanding of the role of the atmospheric planetary boundary layer (PBL) processes in global climate models. The PBL is the lowest part of the atmosphere where the flow is directly influenced by the presence of the surface. An evaluation of the climate model performance in terms of PBL processes such as diurnal variation in temperature and wind and low level clouds will be performed. The next step is to improve the descriptions and new climate projections will be performed.
Results and expected effects
The intended outcome of this project is improved parameterizations in one particular climate model the National Center of Atmospheric Research (NCAR) Community Climate Model with demonstrated improvements in e.g. turbulent surface fluxes at high latitudes and optical properties and extension of low-level clouds. The improved model will be used for projections of future climate.
Approach and implementation
The work will be done in close collaboration with scientists at NCAR, Boulder, USA.
