Atmospheric Rivers and precipitation in the Madeira Island: 10-years analysis
The purpose of this work is to bring more evidence about the Atmospheric Rivers (ARs) occurrence in the North Atlantic Ocean (NAO) and their relationship with significant precipitation in the Madeira Island during 10 winter seasons. In this study, the meridional water vapor transport associated to t...
