Meteorologische und hydrologische Registrierungen an der Pegelstation Vernagtbach-Charakteristika und Trends ausgew?hlter Parameter

摘要

In this article, time series of air temperature, humidity, shortwave incoming radiation, precipitation and discharge from the Pegelstation Vernagtbach (2640 m a. s. 1.) are presented on the basis of averages for the ablation seasons since the middle of the 1970ies. Air temperature, humidity and discharge show clear positive trends, precipitation a smaller one with large variations. For the shorter shortwave incoming radiation series, which is available continuously since the beginning of the 1990ies, no significant tendency can be found. For selected characteristic periods (1981-1985, 2001-2005, 1974-2009), averaged daily discharge is presented as well as tendencies for the months May and June, which display the changes in the annual course of the glacier discharge. The text concludes with a short discussion of the interactions between the different quantities.
