Abstract

This paper presents and analysis of the highest wind speed values recorded at the Meteorological Observatory of the Maria Curie-Skłodowska University in Lublin. The study uses values recorded data (3 times a day) for the period 1981-2005. During the 25 years of the study period there were 19 occasions of wind speed ≥ 10 m·s-1 and 14 cases of winds gusting at or over 20 m·s-1. Both kinds of situation were noticed most often in January and did not occur in May, June, July or August.
