Abstract

The goal is to know the most characteristic weather types and their trends, and how they associate with teleconnection patterns. The presence of the Southeastern Pacific High is essential: anticiclonic days (ANT) days catch up a frequency of 54%, advective types (ADV) types a 31% and ciclonic days (CYC) days a 15%. South and SE circulations are frequent between November and March, and SW, W and NW emphasize from May to September. High pressure types decrease, being actually the directional types the most frequent ones. The best associated pattern to the Jenkinson y Collison (J&C) types is the Antarctic Oscillation, especially with the A and S ones.
