Water drops found in natural rains acquire the simple, spherical forms at only the smallest sizes. Both laboratory and field research reveal that the larger sized raindrops undergo considerable deviation from a spherical shape. We review the evidence for deformed drops and show a technique for parameterizing the drop surface in accordance with the forces acting on falling raindrops.
