  Wind affects the stability and maneuverability of UAVs, which can be
particularly dangerous when operating near obstacles or each other. In order to
test the effectiveness of formation control laws and the impact of windy
environments on the vehicles, spatio-temporal wind fields must be modeled. Each
vehicle within the formation experiences unique wind conditions, but these
conditions are correlated to the conditions experienced by the other vehicles.
This report develops a spatio-temporal model for over-land and over-water
environments that produces a representative wind field capable of running on a
personal computer that also includes turbulence and gusting.
