Climatic variability and tendencies in central chile in the 1950-2010 period by determination of the Jenkinson y Collison synoptic types

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.
