The Pacific Decadal Oscillation (PDO) is defined as the first principal component of the EOF (Empirical Orthogonal Function) of the SST (Surface Sea Level Temperature-) in the North Pacific. Several studies show that it is significantly associated with snowfall in the Arid Andes. The present work proposes to describe the process that leads to said teleconnection, that is, the spatio-temporal association of the PDO with the factors that affect rainfall in them. It was concluded that the PDO: Increases SST in the ENSO area, has an inverse relationship with MLSP and westerlies, weakening ASPSO and 500mb geopotential.
