Abstract:

This article reviews the occurrence and variability of extreme precipitation on the northern slope of the Tatra Mountains (southern Poland), using rainfall amounts of duration from 1 to 30 days. Daily data from 76 years (1927-2002) are used for the Hala Gąsienicowa meteorological station at 1520 m a.s.l. This is the place with the heaviest rainfall in Poland. The highest daily precipitation total (300 mm) was recorded on 30 June 1973 during a northern cyclonic situation. For longer durations extreme values of precipitation were observed during different years. In July 1934 the highest 3-day total reached 422 mm, and during the 11 days between 16 to 26 July 2001 the total amount of rainfall reached 500 mm. In the last 7 years the precipitation totals and the number of extreme events are distinctly greater than in the previous part of the analysed 76 years period, although a strong influence on the results may be the data from the extreme year 2001. However, an earlier period saw extreme precipitation concentrated during the years 1958-1978. A transition to a rather wetter phase of climate has been noted since 1995. However, there is no sign for any of the elements studied of any departure that has exceeded the values typical for fluctuations of climate in the 20th century, and which could therefore be taken as indication a permanent change in the climate.

Abstract:

The article presents the variability to selected extreme climatic phenomena in Poland in the second half of the 20th century. The main attention is paid to the search for exceptional values for indicators or trends that might be regarded as effects of global warm-ing. Among the circulation indicators considered are the variability to the influx of Arctic and tropical air masses in the period 1951-1999, as well as the numbers of days with fronts. In turn, elaborated for the period 1966-1999 was the variability in absolute maxima and minima for pressure, as well as extreme values for pressure tendency, and the occurrence of very strong winds. The greatest changes were found to have occurred in the case of extremes of temperature: from 1982 onwards in the case of absolute maxima and from 1973 on in the case of absolute minima and amplitudes of temperature. These generally attest to an increase in the oceanicity of the Polish climate. In the case of extreme precipitation events, a transition to a rather wetter phase of climate has been noted since 1995. However, there is no sign of any departure for any of the elements studied that has exceeded the values typical for fluctuations of climate in the 20th century, and could therefore be taken as indicating a per-manent change in the climate.

Abstract:

Climatic changes in Southern Poland, including the Carpathian Mountains are shown in regional and local scale. There are discussed: changeability of the circulation indices during the winter season and fluctuations of the air temperatures based on the instrumental observations in the mountain stations. The influence of climate is referred to the secular changes in the width of tree rings in Tatra Mountains and the thermal feelings of human body. Local changes of the radiation inflows are characteristic features of developing urbanization.

Keywords: climate change, circulation indices, air temperature, sunshine duration, precipitation, long-term instrumental observations, Carpathian Mountains, dendroclimatologi-cal data, thermal sensibility of human body, transparence of atmosphere

The methods of constructing climatic maps of various scales for mountainous and upland territories exemplified by the maps prepared for southern Poland

Abstract:

The aim of this paper is to present the methods of constructing climatic maps of various scales for mountainous and upland territories worked upon in the last ten years in the Department of Climatology of the Geographical Institute of the Jagellonian University based on investigations carried out in Southern Poland. This paper forms a contribution to the discussion on drawing general and detailed climatic maps useful for estimating the qualities of the natural environment, and solving numerous economic problems, especially those of spatial planning.
