These settings are comparable to the Gravity parameters.
Strength Increasing Strength increases the wind effect. Strength less than 0.0
creates a suction. It repels particles moving in the same direction and attracts
particles moving in the opposite direction. When Strength is 0.0, the Wind
warp has no effect.
Decay When Decay is set to 0.0, the Wind warp has the same strength
throughout world space. Increasing the Decay value causes wind strength to
diminish as distance increases from the position of the Wind warp object.
Default=0.0.
Planar Wind effect is perpendicular to the plane of the Wind warp object,
throughout the scene.
