Precipitation in the Madeira Island over a 10‐year period and the meridional water vapour transport during the winter seasons
ABSTRACT In this paper, a 10‐year daily accumulated precipitation analysis of Madeira highland is presented, as well as the relationship between meridional water vapour transport during 10 winter seasons and the precipitation recorded in the island during the same period. Here, the meridional water...
