“…There are no systematic in situ observations of sea waves during bora in the study area, therefore, we used satellite altimeter measurements as the main source of information in this study as well as in several other studies dealing with the sea waves in the Arctic (e.g., [16,23]). We created a database of altimetry measurements of wind speed and significant wave height (SWH) in the Novaya Zemlya region (46 • E-66 • E longitude, 70 • N-78 • N latitude) during bora from CryoSat, Envisat, ERS (European Remote-Sensing Satellite), Geosat, GFO (GEOSat Follow-on), SARAL (Satellite with ARGOS and AltiKa), and Sentinel satellites for the period from 1985 to 1988 and from 1991 to 2018.…”

Influence of Novaya Zemlya Bora on Sea Waves: Satellite Measurements and Numerical Modeling

This paper investigates for the first time sea waves during Novaya Zemlya bora—a downslope windstorm on the western coast of the archipelago during eastern winds—using a statistical and case-study approach. Statistical analysis of altimeter data off the western coast of Novaya Zemlya during bora shows that, despite strong wind forcing, the frequency of hazard wave heights was low due to the limited fetch. This result was confirmed by the high-resolution numerical simulations of two severe bora episodes. However, the influence of bora on sea waves in some cases was significant: bora increased wave height at a distance from shore greater than 200 km and wave height anomaly was up to 2–3 m. The influence of the wind input parametrization choice during bora is great in the coastal region; however, parametrizations with fetch-limited modifications and strong-wind adopted aerodynamic drag coefficient do not improve the modeling results in the open sea where altimeter data are available.
