Meteorological conditions at Arctowski Station during 2013–2017 were presented against the background of regional climate changes, especially air temperature decline. Air temperature, relative air humidity, air pressure, solar radiation, wind speed and direction, snow cover and precipitation were collected with an automatic weather station and manual measurements and were further analysed. The obtained results were compared with data from previous years and with data from other stations located on King George Island. Our observations confirm that the vicinity of Arctowski Station experienced a decrease in air temperature during summer, which supports the hypothesis of regional cooling.

The article presents the biometeorological impact of thermal and humidity conditions on the human body in the Hornsund area in the southern Spitsbergen, Svalbard. This was determined based on diurnal air temperature range, the day-to-day variation in average diurnal air temperature and the average diurnal relative humidity. The temporal variability of thermal and humidity biometeorological stimuli in Hornsund was examined for the period 01.11.1978–31.12.2017. A lessening of biometeorological impact was found in the southern Spitsbergen region, including a statistically significant negative trend in strongly- and severely-felt stimuli (according to diurnal air temperature range), and in significant and severe stimuli (according to day-to-day variation in average diurnal air temperature). A non-significant positive trend was observed in the number of days of relative humidity with humid and very humid air. To analyse the spatial variability of the stimuli around the Hornsund fjord, data were used from seven year-round measuring stations for the period 01.07.2014–31.06.2015. The most unfavourable conditions were found on the Hans Glacier, on the summit of Fugleberget and inside the fjord. The paper presents the role of atmospheric circulation on thermal and humidity stimuli. In the Hornsund region, the highest probability of unfavourable sensible temperatures for humans occurring during the year was mostly in winter and early spring. This was related to the advection of air masses from the north-east sector, regardless of baric regime type. It was found that very humid air (> 85%) flowed over Hornsund for practically the entire year from the S–SW as part of both cyclonic and anti-cyclonic systems.

Instrukcja dla autorów


The quarterly Polish Polar Research invites original scientific papers dealing with all aspects of polar research. The journal aims to provide a forum for publication of high-quality research papers, which are of international interest.

We warmly welcome review papers and proposals for thematic Special Issues.

Articles must be written in English. Authors are requested to have their manuscript read by a person fluent in English before submission. They should not be longer than 30 typescript pages, including tables, figures and references. However, upon request, longer manuscripts may be considered for publication. All papers are peer-reviewed. With a submitted manuscript, authors should provide e-mail addresses of at least three suggested reviewers.


Submission of the manuscript should be supported with a declaration that the work described has not been published previously nor is under consideration by another journal.

For text submission, Word file format is preferred. Please use the PPRes style template when preparing the final version of your paper. Pay special attention to writing correctly the list of references with doi. Manuscripts which are not prepared in line with the template will be returned to the authors. Please submit your manuscripts using our online submission system.

The journal does not have article processing charges (APCs) nor article submission charges. No honorarium will be paid to authors for publishing papers.
