A mission of climatological and human biometeorological studies in high mountain: Jungfraujoch,Switzerland

Eight days of September 1985 were spent in a Swiss high-altitude meteorological station. The main facts apparent in this study at the end of summer are a great cold, with a long duration of below zero; sometimes, a severe dryness, decreasing to 1% of relstive humidity but also nearing 99%; a very high wind, blowing to 17 m/s at the maximum; and a considerable variability of these parameters in a very short time. A comparison is made with two nearby, lower altitude stations. The consequences for human confort are also considered.
