Abstract

To grasp the impact of plant cover structure on heat balance structure the components of heat balance of six ecosystems and two landscapes were calculated by using a mathematical model. The following three types of meteorological conditions during the growing season were taken into consideration:

  • Real meteorological conditions for normal, wet and dry years chosen from observations made in the period 1956-1992.
  • Assumed model meteorological conditions for a normal year, (averages from long-term values of meteorological data), and for an extremely dry and hot year, and an extremely wet and cold year.
  • Predicted meteorological conditions resulting from global changes.

The analysis of various meteorological situations has shown that plant cover has mitigating capacities in relation to the presumed effects of global climate change. Thus, in attempts to predict global changes at local level, the mitigating effects of plant cover must be taken into consideration.
