From: Mean winds at the cloud top of Venus obtained from two-wavelength UV imaging by Akatsuki
Mean differences in zonal (a) and meridional (b) winds (m/s) between the two UV filters (283-nm results minus 365-nm results) averaged over the observational period (December 2015–March 2017). c The number of wind differences used to derive the mean at each latitude. See the text for the matching condition. The dashed lines a, b show \(\pm\) the standard deviation at each latitude
