Intra-annual variability of temperature field in the Arctic basin
Abstract
The long-term mean intra-annual variability of the surface temperature field in the Arctic basin is considered on both seasonal and synoptic time-scales basing on the NOAA OI SST reanalysis data. The association of extreme temperature variability areas with the zones of higher horizontal temperature gradients is analyzed. It was found that the seasonal temperature variability is 4–6 times the synoptic one on the Arctic shelf areas, 2,5–3 times that in the basin open areas, and 1,5–2 times in the frontal zones. The highest seasonal and synoptic variability were observed in shallow shelf areas of the basin. The intense synoptic variability of temperature is typical of the open ocean areas with maximum horizontal temperature gradients. The highest values were observed in the West-Spitsbergen and the East-Greenland frontal zones, as well as in the Polar frontal zone near the Medvezhij Island. High level of seasonal variability in the open deep-sea areas was recorded in the inter-frontal zones.
