Thermal conditions of freeze-thaw processes on the cliff face in winter 2019-2020 on the Jeziorsko Reservoir, central Poland

The thermal conditions of freeze-thaw processes acting on the active cliff face of the Jeziorsko Reservoir were recognised based on temperatures of surface sediments measured directly on the monitored cliff face and data from the Kalisz weather station forming part of the network of the Institute of Meteorology and Water Management –National Research Institute (IMWM-NRI) in Warsaw, Poland. In the period from 15.01 to 04.05.2020, directly on the cliff face, 77 freeze-thaw cycles were recorded over 41 freeze-thaw days (FTD), which, on average, corresponds to two cycles per day. Concurrently, in the same period only 33 FTD were recorded in the instrument shelter, which is 20% less. In addition, the outcomes corroborate the view reported in literature; namely, that on the northern hemisphere vertical cliff faces exhibiting western exposure are advantaged in terms of the development of freeze-thaw processes.
