Convergence line

From Glossary of Meteorology
(Redirected from Convergence lines)



convergence line

  1. (Sometimes called asymptote of convergence.) Any horizontal line along which horizontal convergence of the airflow is occurring.

    If mass convergence is taking place in a plane near the surface of the earth, the incoming air must be rising at the convergence line. Hence the lines are often associated with convective clouds.

  2. Radar signature of horizontal convergence at the surface.
