Abstract:

As the lower boundary of the atmosphere, the land surface interacts with the atmosphere through momentum, heat and mass exchanges. Land surface processes have long been recognized as one of the key processes affecting weather and climate, however, although their impacts on climate have been widely studied, their impacts on weather have not received enough attention until recently. This paper reviews the recent research progress on the impacts of land surface elements (soil moisture, etc.), land cover types (topography, land use, etc.) and local circulation (valley-plain circulation, etc.) on weather events, such as strong convection, heavy rainfall, typhoon, high temperature and heat wave, to provide a reference for future study in this field. Even with some progresses made, however, it is noted that further investigation is needed to better understand the physical mechanisms for weather formation, occurrence and development under the influence of land surface processes, especially how they affect the extreme (high impact) weather events, so as to provide scientific support for the numerical modeling study and operational weather forecasting.

Key words: land surface processes, weather research, latest progress
