The aim of the study is to investigate the course of air temperature and precipitation in Łódź Province in 1966–2021. The study uses daily data provided by the IMGW-PIB net from three meteorological stations: Łódź–Lublinek, Sulejów, and Wieluń. The average air temperature in Łódź province is 8.3ºC. When analyzing the annual course of air temperature, the lowest values were recorded in January (2.1ºC on average), the highest were recorded in July (18.4ºC). A growing, statistically significant trend in air temperature was observed at all the stations in the analyzed multi-year period. The rate of changes in the average air temperature in Łódź province reached the maximum value of 0.35°C/10 years at all the three analyzed stations. The average rainfall totals in Łódź province are not very diversified. The average annual sum of precipitation in the analyzed period in Łódź province ranged from 562.2 mm to 597.2 mm. On a seasonal scale, the heaviest precipitation was in the summer months (June–August), and the lowest in winter (December–February), while autumn rainfallwas slightly higher than in the spring. The biggest amounts of rainfall were recorded in July (84.8 mm), while the minimum rainfall was in February (25.8 mm). At all the stations, there was an upward trend in precipitation in the spring and autumn, and a downward trend in the summer. On average, in Łódź province there were 169 days with precipitation.

The paper focuses on changes of the thermal conditions in Piła in 1971–2020. In the study, daily data were obtained from the Institute of Meteorology and Water Management – the National Research Institute, to analyze the variability of the annual, seasonal and monthly average air temperature, develop a thermal classification and determine the variability of the start dates and the length of 6 thermal seasons. The analysis showed an increase in the average air temperature for all of the time intervals. The consequence of the progressive warming was the increasingly frequent occurrence of months, seasons and years with thermal conditions above the norm for the entire studied period. The research also showed statistically significant changes in the dates of the beginning of the spring, summer, autumn and early winter, with the highest trend in the autumn.

This study aims to identify the extent of mountain glacier influence on air temperature in the vertical profile, using the Engabreen glacier (Norway) as an example. An important aspect of the work is also an analysis of the variation in surface temperature and wind conditions in the valley of the Engabreen glacier. The analysis was carried out based on measurement data of vertical air temperature taken over the glacier cavity with sensors mounted to an unmanned aerial vehicle. The field survey was carried out on 25 July 2022 in the afternoon. The results of the measurements may indicate that the presence of the glacier reduces the air temperature gradient with altitude compared to the surrounding areas. Above the glacier, the air temperature in the vertical profile increases with height. Based on the profiles taken above the glacier, it was concluded that the surface of the glacier influences the air temperature above it up to an altitude of 37–53 m above ground level.

The study’s objective was to determine the spatial and temporal variability of occurrence of extremely warm days in winter in Poland in 1966/67–2020/21, and to determine the effect of atmospheric circulation on their occurrence. An extremely warm day is defined as a day with a maximum daily air temperature equal to or higher than the value of the 95. percentile. The effect of atmospheric circulation on the occurrence of the analyzed days was determined on the basis on two teleconnection patterns, namely the North Atlantic Oscillation (NAO) and Scandinavia (SCAND). The progressing warming translated into increasingly frequent occurrence of extremely warm days. In terms of the abundance of such days, the following winters stood out in the entire multiannual period: 1989/90, 2015/16, 2006/07, and 2001/02.

The article presents the weather conditions on Mount Szrenica, located in the Karkonosze range in the Sudetes, in 2018–2020. The data come from the Database of Integrated Monitoring of Natural Environment. An average temperature in the presented time was 4,0oC, an average yearly precipitation was 1245.8 mm, an average atmospheric pressure 865.3 hPa, average wind speed 5.1 m/s, average snow cover height 66.3 cm, the sun shone for 1881 hours in a year. Changes in individual values compared to the results published earlier prove the impact of global changes also in this area.
