Zachmurzenie i burze w aspekcie ekstremalnych zdarzeń atmosferycznych
Cloudiness and thunderstorms in the context of extreme atmospheric events

Summary/Abstract: The paper discusses cloudiness in the context of the occurrence of extreme events using records from Krakow ( 1951–2012 ). The variables analysed included the maximum cloud cover, the number of cloudy and overcast days, and the structure of cloud cover. The study also analysed the numbers of days with the Cumulonimbus cloud and a thunderstorm in Krakow and its environs using data from the stations at Gaik-Brzezowa and Łazy ( 1991–2012 ). The number was found to have increased, especially in the cool half of the year, which may be related to the current climatic warming. However, the increase in the number of days with a thunderstorm was greater than in that with the Cumulonimbus cloud.
