Kun Yang, Institute of Tibetan Plateau,
In this talk, I will cover the following activities, which are being conducted at
1. On-going experiments. Current projects include Tibetan Observation and Research Platform (TORP), JICA China-Japan weather disaster project, and CAMP-Tibet follow-up project. These experiments will be introduced briefly.
2. Evaluation of surface radiation budget from remote sensing and surface energy budget from a land data assimilation system. The Plateau harsh condition represents an extreme of weather and climate and, therefore, the observations could be used to validate a scheme or a model’s universality. GEWEX-SRB (surface radiation budget) and ISCCP-FD (radiation flux data) as well as the latest
3. Process studies. (1) Due to strong solar heating, there are very large ground-air temperature gradients near noon. We developed a scheme to parameterize sensible heat fluxes for very large ground-air temperature gradient and this scheme was widely evaluated across
4. Extension to climate change studies. We tried to fill in the gap between experimental studies and climate change studies by combining high-resolution experimental data and low-resolution CMA (Chinese Meteorological Administration) data. Indeed, we found experimental studies can contribute to our understanding of climatic trend of surface energy budget.
