Polar Vortex Forecast February 2024 Bangalore. A new polar vortex is developing in the stratosphere over the north pole as nights get longer over the polar regions and temperatures drop. Let’s start with a continuous analysis of the arctic oscillation (ao) and the polar vortex (pv).

By the end of february to the beginning of march, only cold air remains and there is no longer a polar vortex. Based on the recent forecast models, the full breakdown of the polar vortex into a major sudden stratospheric warming is expected to be brief.
