Resumo: | This work analyzed the 3.5 land surface scheme coupled in the Regional Climate Model RegCM4 (RegCLM), seeking to identify the impact of this coupling in the climatology and in the interannual variability, mainly in the Southeast of Brazil. The climatology analysis showed that the RegCLM, for DJF, is more humid than the set of observations used, overestimating the South Atlantic Convergence Zone (SACZ) due to the RegCLM simulate more intense the northeast trade winds, and with this, there is a transportation of moisture from the Tropical Atlantic Ocean to the continent trhought the Low Level Jet (LLJ), intensifying the SACZ. For air temperature, RegCLM is colder than observations in the SDE region. This result also occurs in the analysis of the annual cycle and, especially in winter, reaching the difference of 1.8oC. During summer, lowest simulation errors were found for this variable. For the interannual variability for the SDE, the simulated precipitation presents an intensify pattern of the signal and reverse the phase of the observed anomaly. For air temperature, the simulation agrees with the observations, intensifying in some years the anomalies. |
