The U.S. Naval Research Lab (NRL) is assisting an investigation into unexplained arctic phenomena associated with the sudden formation of intense “polar lows” that are known to lead to hazardous conditions at sea.
Since late February, a field campaign, the Cold-Air outbreak Experiment in the Sub-Arctic Region, or CAESAR, has been collecting data on the phenomenon underlying these potentially dangerous arctic events by observing cloud formations and other Arctic meteorological conditions.
“These subjectively beautiful clouds serve as a natural lab to study cloud dynamics at a wide range of scales,” said Bart Geerts, a professor of atmospheric science at the University of Wyoming and a CAESAR principal investigator, last month.
Based in Kiruna, Sweden, CAESAR is comprised of an international team of scientists and is attempting to determine the meteorological processes underlying Arctic cold-air outbreaks (CAOs), events that pose a threat to sailing vessels and can potentially cause disruptions to Arctic weather systems.
