Subseasonal swing of cold and warm extremes between Eurasia and North America in winter of 2020/21: initiation and physical process

Shuangmei Ma et al.

Summary: Eurasia and North America experienced a strong subseasonal swing of surface air temperature extremes in the 2020/21 winter. This swing had severe impacts on human activities and the global economy. The alternating extremes were caused by annual cycle anomalies of surface air temperature and the phase transition of the North-Pacific-Oscillation-like Rossby wave.

Seasonal Cumulative Effect of Ural Blocking Episodes on the Frequent Cold events in China during the Early Winter of 2020/21

Yao Yao et al.

Summary: Based on the analysis, this paper demonstrates that China experienced several extreme cold events during the early winter of 2020/21, with record-breaking temperatures. The outbreak of these extreme cold events can be attributed to a massive merging Ural blocking (UB) ridge over the Eurasian region. Additionally, the UB has significant impacts on sea-ice cover and atmospheric circulation, leading to the frequent occurrence of extreme cold events.

On the Two Successive Supercold Waves Straddling the End of 2020 and the Beginning of 2021

Cholaw Bueh et al.

Summary: This study analyzes the distinct features of two supercold waves that hit China in 2020 and 2021 and finds their association with the accumulation of cold air in Siberia under the Arctic amplification background, as well as the impact of different blocking circulations and the collision of the Asian blocking pattern with the polar vortex deflection towards East Asia.

An Isentropic Mass Circulation View on the Extreme Cold Events in the 2020/21 Winter

Yueyue Yu et al.

Summary: This study investigates the mechanisms behind the extreme cold events that occurred in East Asia and North America during the 2020/21 winter. The results suggest that the strengthening of the low-level equatorward cold air branch of the isentropic mass circulation (IMC) played a crucial role in these events. The intensification of cold air transport in East Asia was influenced by Arctic sea ice loss, while the weakened cold air transport in North America was associated with warmer sea surface temperatures in the northeastern Pacific.

Influence of Major Stratospheric Sudden Warming on the Unprecedented Cold Wave in East Asia in January 2021

Yingxian Zhang et al.

Summary: In early January 2021, an unprecedented cold wave hit East Asia, which was influenced by a major stratospheric sudden warming event. This event caused the displacement of the stratospheric polar vortex to East Asia and triggered an inverted omega-shaped circulation pattern, leading to the outbreak of the cold wave.

The Alternating Change of Cold and Warm Extremes Over North Asia During Winter 2020/21: Effect of the Annual Cycle Anomaly

Minjie Yu et al.

Summary: The large-scale cold and warm spells in North Asia have caused a subseasonal alternation of extreme surface air temperature. The synergistic effect of the annual cycle and intraseasonal oscillation of temperature and circulation anomalies is responsible for temperature extremes before and after mid-January 2021.

The 2020/21 Extremely Cold Winter in China Influenced by the Synergistic Effect of La Nina and Warm Arctic

Fei Zheng et al.

Summary: This report highlights that the frequent cold surges in the winter of 2020/21 were mainly caused by large-scale atmospheric circulation anomalies in the mid-high latitudes of the Northern Hemisphere, with the synergistic effect of the warm Arctic and La Nina intensifying these anomalies.

The Nature and Predictability of the East Asian Extreme Cold Events of 2020/21

Guokun Dai et al.

Summary: Three extreme cold events occurred in China between December 2020 and mid-January 2021, leading to drastic temperature drops and setting new low-temperature records. These events were associated with low Arctic sea ice extent and a La Nina event, with the third event showing the highest predictability in forecasting East Asian cooling. Further research on the predictability of these cold events and their relationships with atmospheric initial conditions, Arctic sea ice, and La Nina is warranted.

Extreme Cold Events from East Asia to North America in Winter 2020/21: Comparisons, Causes, and Future Implications

Xiangdong Zhang et al.

Summary: The three extreme cold weather events were caused by anomalies in three oceans and interactions between Arctic-lower latitude atmospheric circulation processes, influenced by a sudden stratospheric warming event. These events disrupted the stratospheric polar vortex and led to cold air outbreaks, with implications for prediction skill and policy decision making for resilience in One Health, One Future.

Influence of the NAO on Wintertime Surface Air Temperature over East Asia: Multidecadal Variability and Decadal Prediction

Jianping Li et al.

Summary: This study investigates the influence of winter NAO on East Asian surface air temperature, finding a significant correlation and multi-decadal variability. The observed decreasing trend in winter EASAT in recent years suggests a high probability of extremely cold events in East Asia winters. The winter NAO leads the detrended winter EASAT by 12-18 years, with the most significant positive correlation at a lead time of 15 years.

Intraseasonal contributions of Arctic sea-ice loss and Pacific decadal oscillation to a century cold event during early 2020/21 winter

Ruonan Zhang et al.

Summary: An unprecedented cold event occurred in Central and eastern Eurasia during the 2020/21 winter, with potential drivers being the concurrent Arctic sea-ice loss and extratropical Pacific decadal oscillation (EPDO) warming. Simulation experiments suggest that sea-ice and autumn EPDO play important roles in driving cold events, with their combined effects showing the largest cooling response.

Atmospheric circulation regime causing winter temperature whiplash events in North China

Shuangmei Ma et al.

Summary: The study found that drastic temperature shifts during winter temperature whiplash events in North China are closely related to the southeastward propagation of dipolar anomalous temperatures in the middle and lower troposphere over the Eurasian continent, showing different temperature patterns during negative and positive events.

A Connection of Winter Eurasian Cold Anomaly to the Modulation of Ural Blocking by ENSO

Binhe Luo et al.

Summary: This study found that ENSO can significantly influence winter air temperature over central Eurasia by modulating the strength and location of the cyclonic anomaly of Ural blocking. Specifically, during La Nina (El Nino) winters, a strong (weak) cyclonic anomaly of Ural blocking on the southeastern (eastern) side of the Ural Mountains leads to a strong (weak) cold anomaly over central Eurasia, especially over East Asia.
