e/Denver Convergence Vorticity Zone

Information
has gloss	eng: The Denver Convergence Vorticity Zone (DCVZ) is an atmospheric phenomenon characterized by convergent winds east of the Denver metropolitan area, typically 50 to 100 km in length and oriented in a north-south direction. This meteorological feature was subject to academic scrutiny following a large outbreak of Denver-area tornadoes in 1981, and has been used to explain the propensity of the area to spawn landspout and supercell tornadoes. The DCVZ is often associated with the Denver Cyclone effect, though the Denver Cyclone is considered a distinct atmospheric phenomenon by some observers.
