“…There, they occur mainly in the Norwegian and Barents Seas [ Rasmussen and Turner , ] but are also observed in other open sea areas, like the Labrador Sea and the Greenland Sea [ Rasmussen , ; Rasmussen et al ., ; Moore et al ., ], and occasionally to the north of the United Kingdom [e.g., Hewson et al ., ]. Additional PL genesis regions are the Okhotsk Sea and the Japan Sea [ Ninomiya , ; Ninomiya et al ., ; Yanase et al ., ; Mitnik et al ., ], the far Northeast Pacific and the Bering Strait [ Businger , ; Businger and Baik , ; Douglas et al ., ], and other higher latitude areas where and when sea ice is absent, like Baffin Bay and the Beaufort Sea [ Parker , , Rasmussen et al ., ]. With the recent rapid decrease in sea‐ice extent over the Pacific sector of the Arctic during intermediate seasons, the Chukchi Sea might also see more PL developments especially in the fall season [e.g., Inoue et al ., ].…”

[1] Polar Lows (PLs) are intense meso-cyclones forming in winter at high latitudes over open water. Using several datasets of PLs over the North Atlantic, the synoptic environment conducive to their development is determined. The 500 hPa geopotential height, the difference between the sea surface temperature and the 500 hPa air temperature, the near-surface wind and air temperature, and the 300 hPa potential vorticity present significant anomaly patterns over large areas centered over PL genesis zones, suggesting cold air outbreaks and stratospheric intrusions. PLs develop within a northerly flow in the Norwegian Sea, a northeasterly flow in the Barents Sea and a westerly flow in the Labrador Sea. PLs form after a certain build-up, the outbreak day being marked by strong winds and PV intensification. The relationship between PLs and daily weather regimes over North Atlantic-Europe is then investigated. Regimes have a typical lifetime of 8-10 days, similar to the large-scale anomalies associated with PLs. Over the Norwegian and Barents seas from 1999 to 2011, 37% of PLs are observed during the Atlantic Ridge regime (AR) and 28% in the negative phase regime of the North Atlantic Oscillation (NAO), whereas PL probability of occurrence is reduced by half for the positive phase of NAO and the Scandinavian blocking (SB) regimes. Over the Labrador Sea, most PLs occur during NAO+ while they are almost absent during NAOÀ. Demonstrating the temporal variation of key factors based on an updated dataset and relating PLs to weather regimes will introduce novel and important elements in PL forecasting methodology.

“…Tsuboki and Asai (2004) describe the process of strong convergence forming east of the Korean Peninsula, with substantial sensible and latent heating from the Sea of Japan, leading to the formation of these mesoscale cyclones. Intense Sea of Japan cyclones can cause substantial wave activity and subsequent coastal damage along the east coast of Korea (Lee and Yamashita, 2011;Oh and Jeong, 2014;Mitnik et al, 2011) in addition to significant snowfalls across Korea. Clearly, an accurate representation of air-sea interactions in NWP models is important when forecasting the impacts of winter cyclones and accompanying heavy snowfalls across the Korean Peninsula.…”

Abstract. As a component of the National Aeronautics and Space Administration's (NASA's) Weather Focus Area and Global Precipitation Measurement (GPM) Ground Validation participation in the International Collaborative Experiments for the PyeongChang 2018 Olympic and Paralympic Winter Games' (ICE-POP 2018) field research and forecast demonstration programs, hourly ocean surface meteorology properties were retrieved from the GPM microwave observations for January–March 2018. In this study, the retrieved ocean surface meteorological products – 2 m temperature, 2 m specific humidity, and 10 m wind speed – were assimilated into a regional numerical weather prediction (NWP) framework. This explored the application of these observations for two heavy snowfall events during the ICE-POP 2018, on 27–28 February and 7–8 March 2018. The Weather Research and Forecasting (WRF) model and the community Gridpoint Statistical Interpolation (GSI) were used to conduct high-resolution simulations and data assimilation experiments. The results indicate that the data assimilation has a large influence on surface thermodynamic and wind fields in the model initial condition for both events. With cycled data assimilation, a significantly positive influence of the retrieved surface observation was found for the March case, with improved quantitative precipitation forecasts and reduced errors in temperature forecasts. A slightly smaller yet positive impact was also found in the forecast for the February case.
