- The United States has been experiencing severe winter storms is caused by the expansion of the polar vortex.
- The polar vortex primarily affects the countries situated in the Northern Hemisphere’s mid to high latitudes.
- The polar vortex spins anticlockwise around the North Pole with wind speeds of about 155mph (250km/h).
- There are two types of polar vortexes – tropospheric and stratospheric.
- The tropospheric polar vortex occurs at the lowest layer of the atmosphere where most weather phenomena take place.
- It extends from the surface up to about 10 km to 15 km
- The vortex creates milder weather across northern latitudes.
- The stratospheric polar vortex occurs at around 15 km to 50 km high.
- Unlike the tropospheric polar vortex, the stratospheric polar vortex disappears during the summer and is the strongest during the autumn.
