High winds during a storm event can mechanically shake precipitation from the canopy and thus reduce interception loss. Winds during evaporation can either shake precipitation loose or increase the rate of evaporation and decrease the time until maximum interception capacity is attained.
What factors affect interception loss?
Factors Affecting Interception:
- (i) Type of Vegetation:
- (ii) Wind Velocity:
- (iii) Duration of Storm:
- (iv) Intensity of Storm:
- (v) Season of the Year:
- (vi) Climate of the Area:
How does wind affect interception?
5, interception is independent of wind velocity. Von Heuveldop (1973) even found a decrease of interception with wind velocity and Calder and Wright (1986) found the resistance to evaporation independent of wind velocity, although wind velocity should increase the evaporation rate and thus interception loss.
