From Glossary of Meteorology


A stationary bank of cirriform cloud marking the upper portion of the system of lenticular clouds formed in the lee wave produced by flow across the Sudeten Mountains in Central Europe; a type of foehn cloud.

The Moazagotl is a typical phenomenon in the cool season and most frequently occurs in spring and autumn. It primarily occurs when the air is conditionally unstable and wind speeds exceed certain critical values. The Moazagotl cloud has been used as an indicator of vertical motion for sailplane flights.

Compare Bishop wavechinook arch.
