Omega highs are characterized by their omega-shaped pattern in the upper atmosphere, their blocking nature which disrupts the normal flow of weather systems, their persistence over a geographic area for extended periods, and their ability to keep troughs stationary. They do not typically form in zonal flow conditions, which involve more west-to-east air movement and less of the north-south meandering associated with omega blocks.
