Short summary
Raindrop shapes and fall velocities are presented for two high-wind/turbulent events. Results show strong gusts, directional wind shifts and/or inferred high turbulence intensity are correlated with reduced fall speeds, reaching values ~ 25–30 % less than the expected values, i.e. sub-terminal fall speeds. Significant percentage of asymmetric drops deviating from the most probable ax-isymmetric shapes was also detected during high turbulent intensities.
