Sažetak
In the period between 1991. and 2000., bioclimatic data were collected from 34 meteorological stations in the Austrian State of Styria. The equivalent temperature served as an indicator for the thermal action complex; during the winter months, wind-chill temperatures were used (thermal action complex). Finally, the geographic and seasonal distribution of weatherbiotropic intensity was studied (neurotropic action complex).
The mean values and frequency distributions of the equivalent temperature show that with the exception of mid-summer, cool conditions predominate. Comfortable conditions prevail only between June and August, below 500 meters. However, during that period, the heat-stress situations are more noticeable, although they are clearly less frequent than comfortable conditions. The results for wind-chill temperatures show that during the winter months, up to an altitude
of 1500 meters, the extremes of "bitter cold" and ,,very cold" are very infrequent, at least during daylight hours. In the open alpine region, however, cold stress clearly predominates.
For the calculation of the weather-biotropy, only 12 stations could be used as there was no air pressure available at the rest of the stations (compare with Figure 1).
On the average, biotropic assessments show a predominance of biologically favourable days throughout Styria. No regional differences appear in meteorotropic stimuli, but seasonal differences
do exist. Thus, there are clearly more biologically stressed days in the months of winter than in summer, whereas the maximum number of days with favourable biotropic conditions is in summer.
