Recent Progress in the Land-Surface and Hydrological Process Studies
This paper reviews recent advances in the field observation of land-atmosphere interaction, the development of land-surface and hydrological model, and the impact of land surface processes on the regional climate variations at the Institute of Atmospheric Physics, Chinese Academy of Sciences. Firstly, the field campaigns over different characteristic land surfaces have been briefly summarized, and the discrepancies of current land surface models in the simulation of land-atmosphere interaction over arid and semi-arid regions have been revealed by using the field observation data, and the necessity of the parameter calibration for the land surface model has been pointed out; then, the development of land surface model have been introduced, with focus on the parameterization of fractional snow cover and permafrost processes; the spatial-temporal distribution of soil moisture and its importance in the weather forecast and seasonal climate simulation and prediction have also been introduced in this paper, together with the development of large-scale distributed hydrologicai model system and its applications over China. Finally, the prospects for studies of the land-surface and hydrologicai processes are briefly discussed.
