Combined impact of the cold vortex and atmospheric blocking on cold outbreaks over East Asia and the potential for short-range prediction of such occurrences
This study explores the consequences of independent and combined effects of blockings on the northeast Asian cold vortex (NACV), and corresponding cold outbreaks over East Asia (EA) during boreal winters of 1979–2019. The results show that the development of NACV is closely associated with blocking over the Ural Mountains (UB) upstream and eastern Siberia to mid-North Pacific (SPB) downstream. Here we focus on the initial periods before the peak …
Antarctic skin temperature warming related to enhanced downward longwave radiation associated with increased atmospheric advection of moisture and temperature
We investigate linear trends in Antarctic skin temperatures (temperatures from about the top millimeter of the surface) over the four seasons using ERA5 ensemble mean reanalysis data. During 1950–2020, statistically significant warming occurred over East and West Antarctica in spring, autumn and winter, and over the Antarctic Peninsula in autumn and winter. A surface energy budget analysis revealed that increases in downward longwave radiation re…
Collaborative impact of the NAO and atmospheric blocking on European heatwaves, with a focus on the hot summer of 2018
Two intense heatwaves of July and early August 2018 are found to be associated with a European blocking (EB) event accompanied by a series of consecutive positive North Atlantic Oscillation (NAO + ) events. Further analyses show that the collaborative role of an EB event and its upstream NAO + pattern could increase the frequency, persistence, magnitude and scale of heatwaves over Europe. Compared with NAO + -unrelated EB events, NAO + -related E…
What causes extreme hot days in Europe
Atmospheric circulation patterns which promote winter Arctic sea ice decline
The impact of winter atmospheric blocking over the Ural Mountains region (UB) coincident with different phases of the North Atlantic Oscillation (NAO) on the sea ice variability over the Barents and Kara Seas (BKS) in winter is investigated. It is found that the UB in conjunction with the positive phase of the NAO (NAO ^+ ) leads to the strongest sea ice decline. During this phase composites and trajectory analyses reveal an efficient moisture pa…
Weekly cycles in peak time temperatures and urban heat island intensity
Regular diurnal and weekly cycles (WCs) in temperature provide valuable insights into the consequences of anthropogenic activity on the urban environment. Different locations experience a range of identified WCs and have very different structures. Two important sources of urban heat are those associated with the effect of large urban structures on the radiation budget and energy storage and those from the heat generated as a consequence of anthro…
What are the physical links between Arctic sea ice loss and Eurasian winter climate
Rapid sea ice retreat and increases in temperature have characterised the Arctic basin in the last few decades. A number of studies have suggested that these changes have had a direct impact on extremes of weather and climate in the midlatitudes, while others have submitted that the evidence for this may not be robust. Sato et al (2014 Environ. Res. Lett. http://dx.doi.org/10.1088/1748-9326/9/8/084009 ) cast considerable light on this divergence …
