Description :
Regional variations of weather pattern were analyzed along a west-to-east profile across the Southern Andes (53°S), one of the most pronounced climate-divides in the world. The AA. present here a meteorological record from an array of 3 automatic weather stations (AWS) during a time period of 3 yr., 1999-2002. Air temperatures along the profile are highly correlated. The variations of rainfall with wind direction and synoptic weather types are markedly different between the central part of the Andes and Punta Arenas. The results indicate that in order to make references about present or past climatic variations in Patagonia, it is essential to consider the effect of changes in circulation patterns.
