Abstract

The ecophysiological observations and the investigations of the weather dependent vital processes of the forests have clearly proved that the water supply in the main growing-main water consumption period (from May to July) as well as in the critical months (July and August) have crucial influence on the growth, vitality, and organic matter production of the forest. Evapotranspiration rate is higher in these periods; and forest ecosystems are most sensitive to the extreme weather conditions this time. Relationship between meteorological parameters and girth-growth of trees (proportional with organic matter production) can be characterized by a simplified forestry aridity index (FAI) for Hungarian conditions: FAI = 100 TVII-VIII / (PV-VII + PVII-VIII), where TVII-VIII is the average temperature in July and August (°C), PV-VII is the precipitation sum (mm) of the period from May to July, and PVII-VIII is the precipitation sum (mm) of July and August. By this index, the average weather conditions of different climate categories applied in forestry practice can be described. FAI values representative for different species are beech: <4.75; hornbeam-oak: 4.75 - 6.00; sessile oak and Turkey oak: 6.00 -7.25; forest-steppe: >7.25.
