“…In contrast to CAT-sites, slope sites above these locations can be distinctly favoured by warmth (Baumgartner 1962). According to Baumgartner et al (1956), this phenomenon can be defined as phenological inversion. It complicates or even prevents the derivation of vertical gradients of phenological phases (Heigel 1957;Aulitzky 1968).…”

“…It complicates or even prevents the derivation of vertical gradients of phenological phases (Heigel 1957;Aulitzky 1968). Detailed observations in the Bavarian Forest underline the necessity of differentiating between top-, slope-or CAT-sites (Baumgartner et al 1956;Elling et al 1987). In the present study, therefore, the locations of the selected phenological stations were analysed and CAT-sites excluded.…”

“…According to earlier, large-scale studies, the delay of leaf unfolding (LU) of beech is 1-4 days per 100 m altitude increase (Schnelle 1955;Ko¨nig and Mayer 1988;Ro¨tzer 1996;Menzel 1997). A few, more detailed, but temporally and regionally restricted investigations, revealed distinct greater vertical gradients of the beginning of the vegetation period, which result in a slower progress of LU with altitude (Baumgartner et al 1956;Elling et al 1987).…”

Long-term observational data of the phenological network of the German Weather Service (DWD) were used to derive the altitudinal dependence of leaf unfolding (LU), leaf discolouration (LD) and the length of the vegetation period (LD-LU) of common beech (Fagus sylvatica L.) in different regions of Southern Germany. Depending on altitude, the vegetation period starts in Bavaria between the 2nd and 24th May with a delay of around 2 days per 100 m altitude increase (averaged over the last 30 years). In Southern Bavaria, LU starts a few days earlier as well as increases slightly faster into higher altitudes than in the northern regions. This can be explained by a more favourable supply of warmth and radiation in the south. The end of the vegetation period, defined here as the beginning of LD, showed no altitudinal dependence, which reflects an interaction of endogenous and exogenous factors as triggers for LD. In the Bavarian Forest region, altitudinal dependences are strongly influenced by sites which are affected by cold-air tailback ('Kaltluftstau') was obtained. Hence, phenological gradients should only be derived and applied above a phenological inversion zone. The calculated vertical gradients for LU can be used together with available observational data to estimate the beginning of the forest vegetation period of beech for different altitudes of Bavaria.

Zusammenfassung. Im inneren Otztal, einem zentralalpinen sfidlichen Seitem tal des Inn (Tirol, Osterreich), wird das Lufttemperaturklima zweier gegeniiberliegender H/inge (WNW-und ESE-Hang) zwischen 1820 mund 2440m untersucht. Nach einer Beschreibung der Met~umst/inde und der Lage des Stationsgebietes in den kontinental getSnten Innenalpen wird das reliefbedingte Hangklima beschrieben und das Ausmag der ,,warmen Hangzone" im Gangniveau, in der Gangphase, in den Amplituden-, Extrem-und Mittelwerten sowie in der H~iufigkeit nachgewiesen. Darfiber hinaus wurde auch der Einflul~ des Mikroreliefs und der Bestockung im Bereich der oberen Waldgrenze ermittelt. Ferner wird auf die biologische Bedeutung der Temperaturmeliorierung in der ,,warmen Hangzone" fiir die Holzartenverteilung, ffir Assimilation und Atmung (Respiration) der Holzarten und ffir die Dauer der Vegetationsperiode hingewiesen. Summary. In the inner valley of Otz river, a southerly transversal valley of tile valley of the Inn river in the Central Alps (Tyrol, Austria), the air temperature conditions of two slopes, one facing the other, one directed against WNW the other against ESE, has been investigated climatologically in a region between I820 and 2440 m a. s. 1. After a description of the instruments used, the method of the measurements, and the site of the stations in the climatologically continental Inner Alps, the author discusses the slope-climate, caused by the relief of the site, and identifies the extent of the "thermal belt" in level and phase of the variations, the amplitudes, extremes, mean values, and frequencies. Further, he shows the influences of the micro-relief and of the cover density of wood in the region of the upper timber-line. Finally, the biological importance of the temperature-melioration in the warm slope-region for the distribution of species of trees, for assimilation and respiration of the wood and for the duration of the growing season is stressed.
