North American ETCs are large low-pressure systems, such as Nor\u2019easters, that cause damage primarily through strong winds and snow and ice accumulation.<\/p>\n<p>Arctic air outbreaks, typically linked to high-pressure systems, occur when extremely cold polar air plunges south into the mid-latitudes, causing extensive damage due to prolonged periods of sub-freezing temperatures.<\/p>\n<p>KCC stressed that the severity of Arctic air outbreaks may increase as temperatures warm, driven by a phenomenon known as Arctic amplification. Scientists have observed that the Arctic is warming faster than the global average.<\/p>\n<p>A warmer Arctic reduces the temperature difference between the cold arctic air and the warm air in the mid-latitude regions, weakening the polar vortex. When the polar vortex is weak, freezing arctic air is more likely to move into the mid-latitudes, increasing the risk of unusually cold temperatures in areas not prepared for them.<\/p>\n<div class=\"reins-in-every-article\" id=\"reins-1447216551\">\n<div style=\"margin-bottom: 15px\" class=\"alignnone size-full reins-target\" id=\"reins-776772680\" data-reins-trackid=\"184045\" data-reins-trackbid=\"1\"><a data-no-instant=\"1\" href=\"https:\/\/www.ascotgroup.com\/?utm_source=reinsurancenews&#038;utm_medium=display&#038;utm_campaign=reinsurancenews_display_fall_2025\" rel=\"noopener nofollow\" class=\"a2t-link\" target=\"_blank\" aria-label=\"Ascot Group\"><img loading=\"lazy\" src=\"https:\/\/beijingcareer.com\/wp-content\/uploads\/2025\/09\/ascot-728x90-sep2025.jpg\" alt=\"Ascot Group\" width=\"728\" height=\"90\" \/><\/a><\/div>\n<\/div>\n<p>The Version 3.0 update introduces a refined method for calculating the effects of terrain on winter storms.
