Freezing precipitation and the resultant ice glaze can have catastrophic impacts on urban infrastructure, the environment, forests, and various industries, including transportation, energy, and agriculture. In this study, we develop and evaluate regional algorithms for detecting freezing precipitations in the Far East, utilizing the ERA5 reanalysis...

Here, we examine extreme ocean winds associated with intense wintertime extratropical windstorms over the North Pacific. The study was mainly based on NASA Soil Moisture Active Passive (SMAP) L-band radiometer observations allowing the retrieval of ocean wind speeds up to 70 m/s regardless of precipitation intensity. Additionally, we assessed the a...

We study physical mechanisms of the Tumen River water transport in the area of the Posyet Bay (Peter the Great Bay, Sea of Japan). This study is based on the satellite and in situ measurements, and numerical simulation of advection of river water by the current velocity simulated by Regional Ocean Model System (ROMS). The importance of this study i...

Polar lows (PLs) are intense mesoscale weather systems that often cause severe storm winds in the Nordic Seas but were considered as being exceedingly rare in the Pacific Arctic region before sea ice decline. Here, we explore four PLs observed on 18–22 October 2017 in the Chukchi and Beaufort Seas—an area with an exceptionally sparse observation ne...

During the cold season, extratropical cyclones (ECs) are often associated with severe weather events, especially strong winds, extreme ocean waves and heavy precipitations. At the same time, the study of long-term changes in cyclone characteristics is hampered by gaps in observational instruments and un-certainties in cyclonic activity estimates ba...

In the present article, cold-air outbreak (CAO) and polar low (PL) events were examined over the Chukchi Sea during low sea ice extent of the basin in the November–December period, 2015. An analysis of weather events was performed using multisensor satellite measurements, the NCEP Climate Forecast System, version 2 (CFSv2), and Arctic System Reanal...

In the present study Cold-Air Outbreaks (CAOs) associated with storm winds and extreme air-sea exchange conditions are diagnosed over the Chukchi Sea during autumn-winter periods (Sept-Dec) 2014-2016 using multisensor satellite measurements and high-resolution reanalysis dataset. Analysis of the fields of geophysical parameters from satellite and m...

An investigation was conducted to identify the areas of mesocyclonic activity over the Chukchi Sea. The conditions and mechanisms of mesoscale cyclogenesis were revealed and classified. The study was based on the synergistic use of multi-sensor satellite measurement data and the CFSv2 model from the operational analysis of the Climate Forecast Syst...

The work is dedicated to a comparative analysis of winter and summer mesocyclogenesis over the Japan Sea. The study was conducted using multisensory satellite measurements. The winter polar low in the rear of the extratropical (southern) cyclone located over the Pacific Ocean to the east of Japan was analyzed. It is shown that mesocyclonic activity...

Application of satellite passive microwave sensing for the retrieval of key climatic parameters in the Barents Sea is considered. Fields of surface wind, atmosphere water vapor content and cloud liquid water content were found from MTVZA-GY radiometer onboard the Meteor-M N1 satellite and AMSR2 onboard the GCOM-W1 satellite with the use of original...

We investigated the characteristics of mesoscale cyclogenesis over the eastern sector of the Eurasian Arctic (EEA) in 2007 (anomalously low sea ice cover) and 2014 (high sea ice cover) for the period of 2003-2014. The autumn season (September-November) was chosen for investigating as the period of intensification of mesoscale cyclogenesis in EEA. M...

Interannual variability of the cold-air outbreak (CAO) activity over the Sea of Japan (JS) is analyzed using satellite remote sensing and NCEP-CFSR high-resolution reanalysis data set for the period of 1979-2016. The criteria for quantitative definition of CAO are proposed. They are based on satellite microwave passive and active measurements of ne...

A review of the current state of research in the field of numerical modelling and forecasting of cold-air outbreaks over the ocean at high latitudes and associated mesoscale circulations is presented. It is shown that the most relevant tasks are as follows: (1) the improvement of predictability and the adequacy of reproduction of polar mesocyclones...

Intraseasonal and interannual variability of turbulent heat fluxes over the Japan Sea in the cold period of a year (November - March) are studied using the Japanese Ocean Flux Data Sets with use of Remote Sensing Observations, version 2 (J-OFURO2) and the Objectively Analyzed Air-sea Fluxes (OAFlux) with 1° grid resolution from 1988 to 2007.

Determination of the turbulent heat fluxes over high latitude regions becomes more actual problem. The calculation of these fluxes requires the use of bulk aerodynamic method requiring estimates of the sea surface temperature (Tw), near-surface wind speed (W), air temperature (ta), and specific humidity (qa). Errors in algorithms of satellite retri...

The brightness temperatures TBs measured by Aqua AMSR-E and Meteor-M N 1 MTVZA-GY microwave radiometers as well as the total atmospheric water vapor content, total cloud liquid water content and sea surface wind speed retrieved from the TBs are used to study the structure and evolution of severe marine weather systems and to improve temporal resolu...

The intense mesoscale cyclones (MCs) with a comma or spiral cloud system are often observed over the ocean in a cold season. Their size is 100-1000 km and they exist from a few hours till three days. Parameters and development conditions of MCs are studied insufficiently in comparison with synoptic scale cyclones. MCs are an extreme navigational an...

Mesoscale cyclonic activity is one of the characteristics of the cold season in the Japan Sea. High winds and precipitation accompanying intense mesoscale cyclones (MCs) disturb transport and fishery operations in the sea and small sizes and fast development hinders their forecast and detection. Satellite data of visible, infrared, passive and acti...

When cold and dry air passes over the relatively warm ocean, mesoscale convective rolls are formed just offshore in the developing marine atmospheric boundary layer. Bands with the increased water vapor content and cloud streets mark horizontal roll vortices that evolve at first into transitional forms and then into open and closed convective cells...
