NCAR-UCAR

In the simulations, a tight ring of polar vortices forms at around 55 degrees latitude, the equivalent of Earth’s Arctic circle. After forming, the vortices head toward the poles in a tightening ring, shedding vortices as the circle closes, eventually leaving only a pair of vortices directly abutting the poles before they disappear altogether at solar maximum. How many vortices form and their configuration as they move toward the poles changes with the strength of the solar cycle.

Burning more than 1,000 square kilometers of tundra on Alaska’s North Slope, the 2007 Anaktuvuk river wildfire is one of the largest fires to occur within Arctic ecosystems. Berkeley Lab scientist Nick Bouskill led a study that used data from this disturbance event to predict ecosystem recovery as fires advance in a changing climate. (Credit: Bureau of Land Management)
