| Resumo | The West-Central Brazil (WCB) region contains the western portion of the Brazilian Planalto and the headwaters of major rivers, such as Araguaia and Paraguay, which flow into the Amazon and La Plata basins, respectively. It includes a portion of the summertime rainfall maximum where the mean annual cycle of circulation is highly related to the South America monsoon system. The WCB has some monsoon characteristics such as upper level anticiclonic circulation, low-level depression and a temperature maximum. However, the wind reverse does not happen as in Asian monsoon, just the zonal wind changes its direction. Several criteria for determining rainy season onset and demise dates have been applied to the monsoon regions of the world, based on rainfall, winds and cloudiness, among others. The aim here is evaluate the applicability of some monsoon indexes to identify the onset and demise dates and the quality of the rainy season in the WCB. The indexes used are OLR (OI), precipitation and 850-hPa zonal wind (PZWI), vertical shear of meridional wind (SMWI) and vertical shear of zonal wind (SZWI). The data used in this study are pentad of OLR, daily averaged fields of wind from the NCEP/NCAR reanalysis and gridded daily precipitation analyses for Brazil, from the Climate Prediction Center. The period used in all dataset is July/1979-June/1997.The SMWI and SZWI are defined by the difference of 850- and 200-hPa meridional wind in the point 10oS-40oW and the zonal wind in 25oS-55oW point, respectively. These points are selected because the correlation between the precipitation and the shear component wind was higher. Using the PZWI we define the onset (demise) of the rainy season as the first occurrence of 850-hPa westerly (easterly) winds along 60ºW in the band 10ºS-20ºS together with rainfall rates greater (less) than 4 mmd-1 for at least 75% of the subsequent 8 pentads. By OI we define onset (demise) when the OLR mean in the WCB area (10oS-20oS; 50oW-60oW) is less (more) than 235Wm-2 at least 6 of the subsequent 8 pentad. Preliminary results show that the OI and PZWI can be used to identify the onset and demise dates. The SMWI in shows a good relationship with the onset and demise of the some rainy seasons studied and the SZWI did not show good results. Others discussions are also made about the applicability of these indexes in the predictability of the rainy season quality. |
