This article aims to analyse the influence of weather types on meteorological

conditions in Petuniabukta (Svalbard) during July and August of 2016. The paper analyses

the daily courses of air temperature and humidity at four measurement points located on

the west bank of Petuniabukta near Adam Mickiewicz University Polar Station during

two different types of weather conditions: (i) cloudy and windy, (ii) calm and clear.

These weather types, distinguished on the basis of wind speed and cloudiness, allowed

for the creation of composite maps of the synoptic situation (SLP and geopotential

height of 500 hPa distribution) and its anomalies. In the study area, the air temperature

range in windy and cloudy weather conditions was larger (-10°C to 15°C) than that in

sunny and calm weather (0°C to 15°C), which contrasts the range of humidity values.

The diurnal cycle of meteorological elements in sunny and calm days is strongly related

to the sun elevation angle. In the above-mentioned weather types, the air temperature

was higher by several degrees (median 5°C to 8°C) than on windy and cloudy days

(median about 0°C to 6°C) at each measurement point. On days with sunny and calm

weather, a smaller vertical temperature gradient of air is observed (for sunny and calm

days 0.63°C and for windy weather 0.8°C).
