Exempel på orographic

• 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.

• There, the rains were enhanced by moist air rising over the mountain peaks and condensing, a process known as orographic lift.

• Such heavy rainfall typically occurs on the island when tropical cyclones approach, owing to orographic enhancement in the mountainous interior.

• Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall.

• Rainfall can be abundant at times, as mountains very close to the coast create an orographic effect.

• Because of orographic lift, precipitation increases with elevation up to 8000 ft where it slowly decreases to the crest.

• The effect is enhanced when the moving air mass is uplifted by the orographic effect of higher elevations on the downwind shores.

• It forms above the mountain range, usually at the beginning of a chinook wind as a result of orographic lifting over the range.
