AbstractThe present research seeks to identify the role of soil moisture anomalies on the seasonal characteristics and the interanual variability of the atmospheric component of the hydrological cycle over the subtropical region of South America. With this purpose, long term Eta model ensemble simulations with different soil moisture initial conditions are performed to diagnose the corresponding interaction mechanisms. The dependence on other large scale factors like the El Niño-Southern Oscillation (ENSO) cycle is also assessed, by investigating separately El Niño (EN), La Niña (LN) and Neutral (NEU) years. Sensitivity experiments of the model response to soil moisture changes suggest that soil over the subtropical region during the warm season seems to be close to saturation. Consequently, precipitation is not as sensitive to increases of soil moisture as it is to decreases. When the initial soil moisture is decreased, there is a corresponding increase of the sensible heat flux and reduction of the latent heat flux, thereby increasing the Bowen ratio and the Convective Inhibition (CIN), while reducing the Convective Available Potential Energy (CAPE). As a consequence of these changes, two basic mechanisms are affected. On the one hand the reduction of evaporation implies less moisture availability for precipitation; on the other hand, an elevated and drier boundary layer implies a reduction in the moisture supply by the South American Low-level Jet (SALLJ). The two mechanisms act concurrently to reduce precipitation..
