Determining Atmospheric Winds using Satellite Observations

Magnitude and Direction of Forces

The graphical method of determining the resultant of two forces acting at an angle to each other. The two given forces are represented by the red and black arrows. First construct a parallelogram with the two given forces as sides. The direction and magnitude of the net force is determined by drawing an arrow from the point of application of the given forces to the opposite angle of the parallelogram.
