Description:
The Abdus Salam International Centre for Theoretical Physics (ICTP) Regional Climate Model (RegCM) series have been used for a wide variety of applications over China for a number of years, including climate change, land use and present and paleo-climate simulations. Performances of the RegCM have been well examined, and much was learned from these studies.
Atmosphere-ocean coupled General Circulation Models (AOGCMs) are the widely used tools in simulating present climate and conduct sensitivity experiments. In particular, it is the primary tools used for climate change projections. However, due to limited computer capabilities, the resolution of present day AOGCMs is usually not high enough to represent the details of coastline, small scale topography, surface characteristics and other local forcing. This is a major drawback for the community impact modellers that are typically asking for much higher resolution climate model output to be feed inside the impact models.
Located in the East Asian monsoon region, China is a country with complex topography. Most of today's AOGCMs tend to exhibit a poor performance in simulating the climate in China, especially for precipitation. Previous experiments have shown that regional climate models (RCMs) with a higher resolution can greatly improve the simulation of the East Asia monsoon climate. Furthermore, when applied in climate change projection, RCMs not only can introduce finer scale topographically-induced structures in the climate change signal, but can also simulate some significantly different regional scale change patterns compared to the driving GCMs. Such a finer scale structure and detailed climate change information it is essential when the regional model output has to be used as input for example of a hydrological model to more realistically reproduce the discharge characteristics of the basin.
In connection with the impact model community, this workshop proposes to provide lectures and discussions on:
• Example of applications of RegCM in East Asia/China and other regions;
• Example of applications of other RCMs over East Asia;
• Introduction of the latest version of the RegCM4.1--new packages, capabilities, and performances;
• Discussion of possible reasons of the model deficiencies in simulating present climate;
• Discussions and plans on the possible improvements of the model over the region
• Example of coupling of RegCM with impact models (hydrology, agriculture,health).
This is follow-up of successful activities of the ICTP series of workshops/schools held either at ICTP or in other parts of the world, with many participants from China and East Asia.
The program will be spread over 4 days. The approximate division of time resources is as follows:
- 1 day for talks on previous simulations by RCMs
- 1 day for introduction on RegCM4
- 1 day for RegCM coupled to impact models
- 1 day for discussions
