Scherlinien
Scherlinien, also known as shear lines, are a meteorological phenomenon characterized by a zone of strong winds with a significant wind speed or direction difference across it. They are typically associated with the boundaries between different air masses, such as cold fronts and warm fronts, but can also occur within a single air mass, especially in the vicinity of thunderstorms.
The presence of a scherlinie can indicate a region of increased instability and turbulence. Pilots often monitor
These zones of wind shear are not always visible and can be detected through meteorological instruments like
