The solution has a pressure force acting on the ridge, which represents the orographic drag.
Zones (windward and leeward) were designated in respect to the central massif whose orographic influences result in a marked precipitation gradient.
The anticyclonic vortex generated by the orographic vortex compression (p > 0) has associated with it a positive free surface deflexion.
The heaviest rainfall occurred through a process called orographic lift in the mountainous interior, leading to hundreds of landslides.
This energy comes from fronts, heating, moistening, or mesoscale convergence boundaries such as outflow and sea breeze boundaries, or orographic lift.
Convective precipitation events (thunderstorms) tend to produce shorter duration storm events than orographic precipitation.
Cirrocumulus lenticularis forms when stable air is forced upward; this is usually due to orographic features, but can occur away from mountains as well.
Marked orographic enhancement over this terrain is evident on radar imagery.
