The observation and simulation of lake-atmosphere interaction processes over several high-elevation lakes of the Tibetan Plateau

Lake-atmosphere interaction is the most important process that can significantly influence catchment water circulation, climate change and ecosystem preservation. However, the in situ measurements are still very limited because of the harsh conditions and difficult environments. In this study, we will introduce the comprehensive measurements over several high-elevation lakes, including Nam Co, Serling Co, Bangong Co, Laang Co. The filed measurements will include lake water temperature gradients, meteorological variables, lake-atmosphere turbulent flux exchanges by eddy covariance measurements and the satellite ice phenology. The results show the obvious under-ice warming before the ice-off events and the improved WRF-Lake model can reproduce the obvious process. The characteristics of meteorological conditions and lake-atmosphere turbulent heat flux will be explained. The long-term trends in lake evaporation and ice sublimation as well as lake ice phenology will be summarized. These datasets and results will show significance for lake process analysis over these data-scarce lakes of the Tibetan Plateau.
