W artykule przedstawiono historię badań meteorologicznych i klimatycznych prowadzonych przez pracowników Uniwersytetu im. Adama Mickiewicza w Poznaniu na dwóch skrajnych obszarach polarnych, to jest Arktyce Wysokiej oraz Antarktyce Morskiej. Badania te głównie obejmowały okresy letnie w Arktyce oraz 4-letnią serię obserwacyjną w Antarktyce. Przeprowadzone badania stanowią podstawę do opisu uwarunkowań klimatycznych współczesnych procesów deglacjacji na skutek globalnych anomalii klimatycznych.

His paper presents the history of meteorological investigation and climatic studiem conducted by employees of the Adam Mickiewicz University In Poznań on two extreme polar regions, ie. The High Arctic and the Maritime Antarctic. These observation mainly included summer periods in the Arctic and 4-year series of observation in Antarctica. They studied climatic conditions of present-day deglaciation processes due to global climate anomalies.

Paper described geomorphological characteristics of landform sets which occur on research areas investigated by Polish geomorphologists on Spitsbergen. These area involve four areas along the western coast of Spitsbergen, i.e. vicinities of the Kaffiøyra, the Werenskioldbreen, the Calypsostranda, and the Hornsund, as wel as one area located in the central part of Spitsbergen, i.e. vicinity of Billefjord with special emphasis on surroundings of the Petuniabkukta. Landforms are characterized in different morphogenetic terms, mainly glacial, peryglacial, deundational, slope, fluvial, even eolian factors and processes.

W pracy porównano dobowe wartości temperatury powietrza mierzonej w okresie 7 VII 2001 – 13 VIII 2003 roku w Petuniabukta położonej w głębi Billefjorden i Svalbard-Lufthavn leżącym na południowym brzegu Isfjordu. Średnia miesięczna temperatura latem (VI–VIII) jest w Petuniabukta o 1 deg wyższa, a zimą (XI–IV) o około 3 deg niższa niż w Svalbard-Lufthavn. W sezonach zimowych średnie dobowe wartości temperatury w Petuniabukta są przeciętnie o 2–4 deg niższe niż w Svalbard-Lufthavn, a latem o 1–2 deg wyższe.

This work presents values of daily air temperature measured in the period 7th July 2001 – 13th August 2003 in Petuniabukta located inside Billefjorden and in Svalbard-Lufthavn located at the southern coast of Isfjord. Mean monthly temperature in summer (June-August) in Petuniabukta was found to be 1deg higher and in winter (November – April) about 3deg lower than at Svalbard-Lufthavn (Tab.1). During winter seasons mean daily temperatures in Petuniabukta are about 2–4deg lower than at Svalbard-Lufthavn and in summer 1–2deg higher (Fig.6). The transition periods are characterized by great differences in temperatures. At the beginning of autumn, in September, thermal conditions in NE (Skottehytta) and S (Svalbard-Lufthavn) part of Isfjord are similar, later, the shorter the day is, the colder the inside of the Billefjorden becomes. In October the temperature at Skottehytta was already 1deg lower than at Svalbard-Lufthavn. In May 2002 it was 2.1deg warmer at Svalbard-Lufthavn and in 2003 it was 2.6deg warmer at Petuniabukta. Taking into consideration similar ice conditions observed during these two years in May both in the vicinity of the station and in the foreshore of the Isfjord, the observed differences in thermal conditions must be attributed to changes in cloudiness and to advection factor. In individual months significant differences in temperatures are noted at both stations. The greatest differences in temperatures between stations are observed from January to April (Tab.3, Fig.3 and 4). During the analyzed period the strongest correlations were noted in the months of the latter part of the year, i.e. from September to December (r >0.9) and the weakest were found in June (Tab.2, Fig.7). 134

In the years 2000 and 2001 observations of meteorological conditions were carried by expeditions of Adam Mickiewicz University in the vicinity of Petunia Bay (Billefjorden, Central Spitsbergen). The meteorological station Skottehytta (78°42,98?N and 16°36,68?E) is located about 50 m of the sea-side, on a rised marine terrace, 5 m a.s.l. The presented database includes the comparison of 30 days period between 10th July and 8th August in both years and a set of values of the whole expedition in 2001 (7th July - 17th September). Observations carried by an automatic station and in five terms a day cycle covered: atmospheric pressure, air temperature, relative humidity, visibility, degree of cloudiness, precipitation, wind speed and direction. The analysis, performed mainly on daily means, partly on maximum values of selected elements and in the case of precipitation on daily totals, showed a confirmation of general characteristics presented in other papers concerning the area under study. In this a slight rise of air temperatures over a multiyear average, low level of precipitation but an increase in the frequency of heavy precipitation events. Wind conditions of the inner-fjord area are strictly connected with local orography, causing frequent foehn-effects. Processes which are described on the example of Petunia Bay can also illustrate the characteristics of global climatic changes, which are clearly visible in high latitudes of Northern Hemisphere.
