Short summary
An atmospheric river (AR) is a long, narrow corridor of moisture transport in the atmosphere. ARs are crucial for moisture and heat transport into the polar regions. Our study examines the role of ARs in the surface energy budget (SEB) in the Arctic. The results reveal distinct seasonality and land–sea–sea ice contrasts due to the impacts of ARs on the SEB. The conclusions provide greater insights into the current and future role of ARs in the Arctic climate system.

Short summary
Extreme warming events with surface temperature going above 0°C can occur in the high-Arctic winter. Although reanalysis data show that these events were short-lived and occurred rarely during 1980–2021, they have become more frequent, stronger, and longer lasting latterly. A dipole pattern, comprising high- and low-pressure systems, is found to be the key in driving them. These findings have implications for the recent changes in sea ice, hydrological cycle, and ecosystem over the Arctic.

This study documents boundary layer stability profiles, from the surface to 500 m above ground level, present in radiosonde observations across the Antarctic continent. A boundary layer stability definition method is developed and applied to the radiosonde observations to determine the frequency and seasonality of stability regimes. It is found that, in the continental interior, strong stability is dominant throughout most of the year, while stability is more varied at coastal locations.

Arctic sea ice is melting fast. This rapid change in the Arctic climate system can also affect the storms in the region. The strong connection between Arctic storms and sea ice makes it an important research subject in warming climate. In this study we compared the results of multiple climate models and ERA5 reanalysis data to each other, with a focus on Arctic storms and declining sea ice.

During 1979–2020, four winter polynyas occurred in December 1986 and February 2011, 2017, and 2018 north of Greenland. Instead of ice melting due to the anomalous warm air intrusion, the extreme wind forcing resulted in greater ice transport offshore. Based on the two ensemble runs, representing a 1980s thicker ice vs. a 2010s thinner ice, a dominant cause of these winter polynyas stems from internal variability of atmospheric forcing rather than from the forced response to a warming climate.

Between January 2012 and June 2017, a small unmanned aerial system (sUAS), or drone, known as the Small Unmanned Meteorological Observer (SUMO), was used to observe the lowest 1000 m of the Antarctic atmosphere. During six Antarctic field campaigns, 116 SUMO flights were completed. These flights took place during all seasons over both permanent ice and ice-free locations on the Antarctic continent and over sea ice in the western Ross Sea providing unique observations of the Antarctic atmosphere.

A new wind shield has been designed to reduce the effects of precipitation gauge undercatch. Tested at three separate sites, it compared well to a well-established refence-quality precipitation wind shield. The new wind shield is smaller and more durable than other reference-quality shields, and it was designed for use in operational weather and climate networks.

Short summary
The Antarctic Precipitation System project deployed and maintained four sites across Antarctica from November 2017 to November 2019. The goals for the project included the collection of in situ observations of precipitation in Antarctica, an improvement in the understanding of precipitation in Antarctica, and the ability to validate precipitation data from atmospheric numerical models. The collected dataset represents some of the first year-round observations of precipitation in Antarctica.
