Warunki meteorologiczne w Zatoce Petunia (Spitsbergen Środkowy) w sezonach letnich 2000 i 2001

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.
