Arctic sea-ice losses in recent decades have been widely documented 26. what five essential elements must be present to provide a 2 Scientists are still working to fully understand the polar vortex: continuous long-term observations are only available after the satellite era, and many climate models struggle to simulate it. The polar vortex is the region of high atmospheric vorticity that forms with the establishment of the winter stratospheric polar jet (Figure 1). The Hatter, often referred to as the Mad Hatter, is one of the most iconic characters from Lewis Carroll’s ‘Alice’s Adventures in Wonderland’. Nonetheless, the earliest scientific papers describing the tropospheric circum - polar flow as a vortex are as old as those describing the stratospheric polar vortex, with initial papers dating back to the late 1940s and early 1950s (e, Rossby introduced the “polar vortex” to the public to much confusion. This locks the colder air into the Arctic Circle, creating milder conditions for most of the United States.
