Mean frequency of occurrence (%) of very strong and extreme cold stress according to the UTCI in Poland in the period November to March (A) and January (B), 1966/67 to 2018/19. UTCI, Universal Thermal Climate Index.

Fig. 3

Multiannual variability of seasonal (November–March) number of days with very strong or extreme cold stress according to UTCI in Suwałki (A) and Warszawa (B), 1966/67 to 2018/19. Solid lines represent respective trends. UTCI, Universal Thermal Climate Index.
