A theory for canting has been developed from the response of raindrops to shear produced by homogeneous, isotropic turbulence. The model predicts small canting angles, with the tangent of the angle having a Gaussian probability distribution about a mean value of zero. Previous reports of large canting angles above the surface layer were based upon interpretations of microwave measurements which were found to be sensitive to the assumed drop shapes and size distributions. However, past measurements using a circular polarization radar technique, sensitive to canting but not to drop shapes and distributions, yielded a narrow distribution of canting angles with a mean near zero in agreement with theoretical expectations.
