  Extreme precipitation in the Arctic region plays a crucial role in global
weather and climate patterns. Bear Island (Bj{\o}rn{\o}ya) is located in the
Norwegian Svalbard archipelago, which is, therefore, selected for our study on
extreme precipitation. The island occupies a unique geographic position at the
intersection of the high and low Arctic, characterized by a flat and
lake-filled northern region contrasting with mountainous terrain along its
southern shores. Its maritime-polar climate is influenced by North Atlantic
currents, resulting in relatively mild winter temperatures. An increase in
precipitation level in Bear Island is a significant concern linked to climate
change and has global implications. We have collected the amount of daily
precipitation as well as daily maximum temperatures from the meteorological
station of Bj{\o}rn{\o}ya located on the island, operated by the Norwegian
Centre for Climate Services for a period spanning from January 1, 1960 to
December 31, 2021. We observe that the trend of yearly mean precipitation
during this period linearly increases. We analyze the recorded data to
investigate the changing pattern of precipitation extremes over the climate
scales. We employ the generalized extreme value distribution to model yearly
and seasonal maxima of daily precipitation amount and determine the return
levels and return period of precipitation extremes. We compare the variability
of precipitation extremes between the two time periods: (i) 1960-1990 and (ii)
1991-2021. Our analysis reveals an increase in the frequency of precipitation
extremes occurrences between 1991 and 2021. Our findings establish a better
understanding of precipitation extremes in Bear Island from a statistical
viewpoint, with an observation of seasonal and yearly variability, especially,
during the period of the last 31 years.
