The paper goal is to show trends of seasonal and year to year variability of long-wave radiation balances of the active surface in SW Poland, taking into account the standard meteorological data from 1971–2000 for Jelenia Góra, Kłodzko, Legnica, Leszno, Opole, Wrocław and Mt. Śnieżka. The average monthly values of these balances were calculated using the selected two variants of the Brunt’s formula (standard and modified by Michałowska-Smak). In the researched 30-year courses prevail positive trends but with different statistical significance. The analysed trends of the average annual values have been compared with appropriate trends of air temperature, sunshine duration and cloudiness to understand the regional relations of the long-wave radiation balance to these parameters of the climatic variability. These analyses are essential part of wider research fields on long-term variability and trends of net radiation fluxes and their components on different active surfaces in Lower Silesia.
