a) Wind direction- Winds blowing from different direction converge and cause load to collide causing some of it to be deposited.
b) Nature of desert surface:
- Wind transportation is more efficient on bare surfaces and hence less deposition there.
- Water surfaces such as oasis and moist surfaces impede transportation through friction causing wind to deposit materials.
- Less transportation on surfaces with vegetation as it reduces wind speed and also binds sand particles together.
c) Obstacles- Objects such as rock masses, land forms and vegetation block and reduce wind speed causing deposition.
d) Changes in weather conditions such as sudden showers halts transportation and causes deposition by washing down suspended materials.
e) Load- Heavy load is deposited before light load when wind energy decreases. When many materials are transported by wind they collide causing each other to be deposited.
