A Sensitivity Test of Effect of Tibet Plateau Soil Moisture on Summer Precipitation and Temperature over China
The Qinghai Tibet Plateau is a sensitive area to global climate change.By using the mesoscale model WRF3.5.1, selecting the Tibet Plateau (26° to 39°N, 73° to 104°E) as a critical area, in order to discuss the possible effects of initial anomaly soil moisture on short term climate change in summer over China.Results show that soil moisture has obvious effects on the regional-scale climate.In wet soil moisture conditions, precipitation in the most parts of China increases, especially in parts of Northeast China and East China;meanwhile, temperature in the most parts of China decreases generally and distinctly.In dry soil moisture conditions, the precipitation in the most parts of China decreases along with rising temperature.In conclusion, wet soil has mainly positive feedback effect on precipitation and negative feedback on temperature.
