metadata.value: In this study we analyzed possible changes in sea surface temperature (SST) caused by the
  passage of polar lows. Polar lows are extreme atmospheric phenomena inherent to high latitudes.
  They develop sea surface wind speeds from 15 m/s up to hurricane force values and are
  characterized by small sizes (on average, 300 km) and lifetimes (less than two days), which
  complicates their detection and study. It is assumed that as in case of tropical cyclones, which
  may considerably lower SST due to intense mixing and entrainment of colder waters to the
  ocean upper mixed layer, polar lows could similarly influence SST. Moreover, in high latitude
  areas, where salt stratification may be present instead of temperature stratification, SST may
  increase due to mixing with a deeper warmer layer. In this study 330 polar lows were analyzed
  using satellite passive microwave radiometer measurements of SST. As a result, 47 cases were
  found in which average SST values changed in polar low forcing areas. Out of these cases, in
  six cases an SST increase of at least 0.5 °С was found, and in fifteen cases an SST decrease of
  at least 0.5 °С was found. This indicates that upper ocean response to polar lows is quite a rare
  phenomenon, which should be further analyzed along with its possible role in the ocean-iceatmosphere
  system.
