Extreme Events and Their Spatiotemporal Variability over Polar Regions

About this Research Topic

Due to polar amplification, the average Arctic temperatures rise at twice the global average rate, leading to a rapid decrease in Arctic sea ice extent. In contrast to decreased Arctic sea ice extent, Antarctic sea ice extent shows a somewhat increasing trend until 2014, followed by an abrupt decrease. There is also an increasing trend in seasonal Antarctic air temperature over the Antarctic Peninsula in the past four decades. Accompanying increasing seasonal mean temperature in polar regions, extreme warm (cold) events also show an increasing (decreasing) trend. Polar extreme precipitation and wind speed events also display an increasing trend. The above change in polar extreme events strongly influences the stability of the ice sheet, ecosystem, and humidity activity. However, the physical processes of polar extreme events and their spatial and temporal variability are not fully understood to date.

This Research Topic aims to improve our understanding of historical and future extreme events in polar regions, including the mechanisms behind the occurrence of extreme events, the variability and change of extreme events, and the main influence factors. These extreme events include heat waves, cold waves, extreme precipitation events, extreme wind speed events, polar storms, and extreme sea ice events.

We welcome various studies based on field observations, remote sensing, statistical analysis, and numerical simulation. Specifically, we welcome all contributions on, but not limited to, the following topics:

• Understanding the physical processes of extreme events in polar regions and the impacts of global warming on them.
• Evaluating the spatiotemporal variability and change of polar extreme events in the past four decades and the main contributing factors.
• Quantifying the impacts of main large-scale climate modes on the occurrences of extreme events in polar regions.
• Predicting how the frequency, strength, and spatial pattern of polar extreme events in the future change.

This Research Topic welcomes the following types of contribution: original research article, review article, opinion, perspective, data reports, and brief research report.


Keywords: Polar climate, Polar weather, Polar sea ice, Extreme events, global warming, large-scale climate modes, Spatiotemporal variability, Tropical sea surface temperature, Atmospheric teleconnection


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
