摘要

本研究验证了赤道太平洋和热带大西洋海温异常对巴西南部地区降雨的可能影响。所使用的雨量站有1977年至2015年的月度数据，分布在整个地区。利用气候预报中心提供的数据库中Niño 3.4和Niño 1 + 2地区的逐月TSM距平，以及南方涛动指数和热带南大西洋逐月温度指数。结果表明，南部地区的降水与热带太平洋的海表温度变化有关，与热带南大西洋的海表温度变化的关系较小。

Relationship between the rainfall index for Southern Brazil and the indexes of the Tropical Pacific and the Tropical Atlantic Oceans

The proposed study verified the possible influences of sea surface temperature (SST) anomalies in the equatorial Pacific and the tropical Atlantic on the rainfall in the southern region of Brazil. The rainfall stations used have monthly data for the period from 1977 to 2015 and are distributed throughout that region. Monthly TSM anomalies in the Niño 3.4 and Niño 1 + 2 areas, the Southern Oscillation Index and the Monthly Tropical South Atlantic Temperature Index were also used, from the database provided by the Climate Prediction Centre. The results show the association of precipitation in the South region with variations in sea surface temperature in the Tropical Pacific Ocean and, to a lesser extent, with sea surface temperatures in the Tropical South Atlantic Ocean.
