Abstract:
Soil moisture plays a fundamental role in the exchange of water and energy cycles between the atmosphere and the land surface through evapotranspiration, which primarily includes bare soil evaporation and plant transpiration of water. The amount of soil moisture will modulate the partition of total available energy at the land surface between sensible heat fluxes and latent heat fluxes and then impact the near- surface atmospheric conditions.
The simulations using the Weather Research and Forecasting (WRF) Model with the Noah land surface model were conducted. First, the longer period with multiyear simulations were conducted for two scenarios representative of past (1979-1986) and current (2004-2011) atmospheric conditions to discuss the impact of the land-air interaction on the meteorological characteristics.
Second, a short-term one-month simulation focused on the weather events were conducted to investigate the effect of soil moisture initializations and soil texture on the land surface hydrologic processes and its feedback on atmospheric fields in Taiwan.
