Arctic Warming and Eurasian Cooling: Weakening and Reemergence
Xu, Xinping; He, Shengping; Zhou, Botao; Wang, Huijun; Sun, Bo (Journal article; Peer reviewed, 2023)The observed Eurasian winter surface cooling from the 1990s to the early 2010s, which is contrary to global warming, has been extensively studied. Previous studies revealed that the surface cooling trend has significantly ... -
Atmospheric Contributions to the Reversal of Surface Temperature Anomalies Between Early and Late Winter Over Eurasia
Xu, Xinping; He, Shengping; Zhou, Botao; Wang, Huijun (Journal article; Peer reviewed, 2022)Observations have shown subseasonal reversal of temperature anomalies between early and late winter over Eurasia, which is distinct from the seasonal mean condition. Based on the reanalysis data, the 1800-year control ... -
Contributors to linkage between Arctic warming and East Asian winter climate
Xu, Xinping; He, Shengping; Gao, Yongqi; Zhou, Botao; Wang, Huijun (Journal article; Peer reviewed, 2021)Previous modelling and observational studies have shown discrepancies in the interannual relationship of winter surface air temperature (SAT) between Arctic and East Asia, stimulating the debate about whether Arctic change ... -
The extreme Arctic warm anomaly in November 2020
Fan, Qiyao; Xu, Xinping; He, Shengping; Zhou, Botao (Journal article; Peer reviewed, 2022)In November 2020, the eastern Arctic experienced an extensive extreme warm anomaly (i.e., the second strongest case since 1979), which was followed by extreme cold conditions over East Asia in early winter. The observed ... -
Interdecadal Changes in the Linkage Between North Pacific Oscillation During May and Northeast China Precipitation During Mid-Summer: The Influence of North Atlantic Oscillation
Han, Tingting; He, Shengping; Zhou, Botao; Li, Shangfeng; Hao, Xin (Journal article; Peer reviewed, 2023)Many previous studies have documented the relationship between the North Pacific Oscillation (NPO) and the weather/climate of upstream and downstream regions. However, the stability of NPO precursor signals of East Asian ... -
The Role of Mid-latitude Westerly Jet in the Impacts of November Ural Blocking on Early-Winter Warmer Arctic-Colder Eurasia Pattern
Xu, Xinping; He, Shengping; Zhou, Botao; Wang, Huijun; Outten, Stephen (Journal article; Peer reviewed, 2022)Based on statistical analysis using observations and idealized model simulations, previous studies have revealed the potential response of early-winter atmospheric circulation and temperature anomalies to November Ural ...
