摘要:The study shows a characterisation of atmospheric precipitation of normal and anomalous volume in Lublin and Lvov. To that end the method of determining such precipitation, proposed by Mrugała (1997, 2001), has been used. The source material were monthly precipitation sums at both stations from the period 1961-1990.
The analysis carried out points to specific similarities and differences in the pluviometric regime of both stations. This is the result of their geographic position, local conditions and a different degree of continentalism. Among the similarities will be the general annual course of the characterisations discussed, including mean, maximum and minimum monthly precipitation sums, standard deviation values as well as the values of the upper and lower boundary of the precipitation norm. The differences concern the size of individual characterisations and their diverse course in some months. The frequency of occurrence of a negative precipitation anomaly at both stations is about 1.5 times higher than that of a positive one. In Lvov there is a slight prevalence of months with a positive anomaly, while in Lublin there are more months with normal precipitation. July and December are characterised by the lowest frequency of the occurrence of normal precipitation at both stations simultaneously. The sign of the annual precipitation anomaly depends on the distribution of the frequency of occurrence of a given type of anomaly and its intensity in particular months of the year.
