Convective momentum transport usually describes a vertical flux of the momentum of horizontal winds or currents. That momentum is carried like a non-conserved flow tracer by vertical air motions in convection.

In the atmosphere, convective momentum transport by small but vigorous (cumulus type) cloudy updrafts can be understood as an interplay of three main mechanisms:

The net effect of these interacting mechanisms depends on the detailed configuration or 'organization' of the convective cloud or storm system.
