Foehn-like Wind in the Mountains of Southeastern Brazil as Seen by the Eta Model Simulation

Abstract The present study gives evidence of the occurrence of foehn-like wind on the eastern slopes of the mountains at Southeastern Brazil. A particular case was detected based on observational evidence on 4 July 2015 near the city of Cruzeiro, state of Sao Paulo, on the Serra da Mantiqueira mountains. Results obtained from numerical simulations are consistent with the foehn wind occurrence deducted from the analysis of regional patterns and time series of selected meteorological parameters.

摘要：本研究证实巴西东南部山区东坡存在类焚风气流（foehn-like wind）。2015年7月4日，研究团队于圣保罗州克鲁泽鲁市附近的曼蒂凯拉山脉（Serra da Mantiqueira），基于观测证据发现一例典型类焚风事件。数值模拟所得结果，与通过区域格局分析及选定气象参数时间序列分析推演得到的焚风（foehn wind）发生结论高度吻合。
