EFFECTS OF REGIONAL CLIMATE TENDENCIES ON POTENTIAL USE OF WIND ENERGY IN THE CARPATHIAN BASIN

摘要

Wind climate is analysed on several spatial and temporal scales in the Carpathian Basin. The available wind power is estimated for the entire country based on wind measurements observed in Hungarian climatological and meteorological stations. Furthermore, large scale analysis is carried out for the North-Atlantic-European area using the Hess-Brezowsky macrocirculation patterns. Changes in decadal relative frequency of macrocirculation types are evaluated for the last 120 years. Wind profile is analysed using multilevel wind measurements (from 10 m to 115 m) at the Hegyhatsal area. Significant differences are found in wind speed frequency distributions of vertical levels during the year. A case study is carried out using a mesoscale wind model for surroundings of Hegyhatsal (41 km × 41 km) in order to estimate horizontal and vertical cross sections of wind power fields. Height of a given available wind power level is mapped for larger areas (100 km × 100 km) over Trans-Danubia and over the Great Hungarian Plain demonstrating the importance of siting wind power stations.
