Main Drivers of Recent Record-Breaking Climate Extremes in Antarctica
by Raul Cordero Carrasco
University of Groningen, Campus Fryslân
Date and time: 26 February, 19:30-21:00
Location: Arctic Centre, Aweg 30, Groningen & Google Meets
Language: English
Dr. Carrasco: “In February 2023 the sea ice extent around Antarctica dropped to 1.79 million square kilometers setting a satellite-era record low for the second straight year. Recent anomalies in the Antarctic sea ice, both high and low, underscore the imperative for additional research into the underlying factors contributing to interannual sea ice changes. I have used reanalysis data to investigate the relationship between the strength of the polar vortex and the sea ice extent around Antarctica. I focused on the last two decades, a period marked by significant shifts in stratospheric zonal flow, tropospheric westerly winds, and sea ice cover. My findings suggest that polar vortex dynamics and changes in the tropospheric circulation have played a role in these unprecedented records.”

About IMAKA
IMAKA is the Arctic Centre’s volunteer outreach organisation. We have invited polar scientists, artists or other experts to guest-lecture to a general audience about once every month for about 20 years. IMAKA means ‘maybe’ in Greenlandic and is a central word in their vocabulary and philosophy, as “one never knows for sure” in the Arctic. What we do know for sure, though, is that IMAKA has been forced to switch digital and, rebranded as e-MAKA, we embrace this opportunity to invite guest lecturers from farther afield. Most of our lectures are in Dutch, but some in English.
