Data collected during the period of 1956-2005 at 8 meteorological stations of the Institute of Meteorology and Water Management (IMWM) situated along the Polish Baltic coast were used to provide a quantitative assessment of the North Atlantic Oscillation (NAO) effects on variability of the maximum and minimum air temperatures at the coast. The data were coupled with the NAO (Jones) index values reflecting the difference between normalized atmospheric pressure in Gibraltar (the Azores High) and in Reykjavik (the Icelandic Low). In December-March, NAO effects explain 53-68% of the variability of the maximum air temperature along the coast, the variability of the minimum temperature being accounted for in 43-63%. As a rule, the positive NAO phase (index values > 2.0) brings about an increase in the extreme daily temperature, the negative phase (< –2.0) resulting in a significant reduction of the temperature. A unit increase in the NAO index results in the highest increase of the minimum temperature, by 1.4-2.1oC, in February and January, and in the increase of the maximum temperature by 0.9-1.5oC in those months.

This work concentrates on the analysis of monthly trends of extremes daily temperatures, both minimum and maximum. Analysis was done for the period 2000–2013, based on freely available hourly temperature measurements from 60 Polish stations. Percentiles Tmin10 for minimum and Tmax90 for maximum daily temperature within each month were used as thresholds for selection of extreme temperature values. Count of days with extreme temperatures below/above threshold described every month. Significance of days count trend was analyzed with Mann–Kendall test at the significance level 0.05. For maximum temperatures, significant decreasing trend was found only for 3 station-months. For minimum temperature, 26 significant trends were found and presented in the form of map.

In this work a general characteristics of thermal conditions in Kołobrzeg in the years 1976-2005 is presented. The most important part of the paper is the analysis of extreme temperature days (very frosty, frosty, warm and hot) in relation to the types of atmospheric circulation (according to the classification proposed by Osuchowska-Klein 1978). Daily mean and extreme air temperature data for the weather station in Kołobrzeg were the basis of the paper. The obtained results provide strong evidence that the occurrence of days with extreme air temperatures depends mostly on the atmospheric circulation pattern. Particularly high and low air temperatures in Kołobrzeg, in most cases, are not determined by the character (cyclonic or anticyclonic) of atmospheric circulation, but mainly by the direction of air advection. More detailed analysis has revealed that in the winter months (Dec-Feb) the highest frequency of days with sub-zero maximum temperatures is usually associated with the incursion of continental polar air during anticyclonic circulation types. Conversely, maritime air flow from the Atlantic Ocean most often induced by zonal circulation (especially during cyclonic types over Poland) regularly brings warming in winter. In the warm halfyear (Apr-Sep) strong and persistent advection of the air from the southern or eastern sector (in anticyclonic types: E1, E, D2C and cyclonic ones: F and B) is the most important factor determining the occurrence of warm and hot days in Kołobrzeg. The days with tmax ≥ 25oC appear most rarely during the types accompanied by the winds from the western or northern sector.

On the basis of experimental studies we analyzed the effect of extreme temperatures on the aquatic free-living phases of the life cycle of Chordodes nobilii (Gordiida, Nematomorpha). Bioassays were performed with eggs, larvae, and adults. Eggs and larvae were exposed to 3°C below zero and 40.5°C; adults were exposed to 3°C below zero and to 38.5°C and 40.5°C. The results showed that egg development was inhibited in both tests. Exposed larvae showed a decrease in their infective capacity, which resulted almost null at 40.5°C. Adults exposed to 38.5°C showed mortality ≤10%, at 40.5°C the mortality was 100% and the adult’s mortality at 3°C below zero was 89%. Results indicate that free living stages of Chordodes nobilii are susceptible to extreme temperatures.
