= Upper tropospheric cyclonic vortex
{wiki=Upper_tropospheric_cyclonic_vortex}
An upper tropospheric cyclonic vortex is a large-scale atmospheric circulation pattern that occurs in the upper levels of the troposphere, typically between about 5 to 12 kilometers (16,000 to 39,000 feet) above sea level. This region of the atmosphere plays a crucial role in weather systems and is marked by the presence of low-pressure areas, characterized by counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere.
