This is just basic trig-physics, right? Just find the resultant vector, which is the hypotenuse of a triangle whose legs are the other two vectors. The other number you're looking for is the direction, and you can find the angle of directional difference by taking the inverse tangent of one of the legs over the other.

I say I think because I'm not entirely sure if I'm handling the 'with respect to the air current' thing right. Wow am I rusty. thanks for practice.
