A Critical Examination of the Precipitation Records at the Pic Du Midi Observatory, Pyrenees, Franct of the Pyrenees, includes precipitation measurements. It is well known that the quality of rain and snow precipitation measurements at a mountain station is poor. However, the new interest for all types of meteorological data at high elevation sites in relation with climatic changes leads to criti

Climatic Change and Debris Flows in High Mountain Regions: The Case Study of the Ritigraben Torrenttion to meteorological and climatic factors. The principal trigger mechanisms for such debris flows are abundant rain on the one hand, and snow-melt and runoff on the other hand, or a combination of both. Debris flows linked to rain are likely to be triggered when total rainfall amount over a three-

Regional Snowfall Patterns in the High, Arid Andes, the north Chilean Andes (18. S28. S). The extreme aridity of this region is shown by the absence of glaciers, even at the highest altitudes above 6700 m a.s.l. More knowledge of the present climatic situation is needed to interpret the proxy data of different paleoarchives in this transition belt b

Fifteen tree-ring chronologies from 1200 to 1750 m elevation were developed for ., the dominant subalpine species. Samples were collected along three elevational transects located along the steep west-to-east precipitation gradient from the main Cordillera (mean
