Vertical profiles of wind velocity in the Venus atmosphere from Doppler measurements of Venera 13 and Venera 14.
Abstract
Vertical profiles of wind velocity in the Venus atmosphere were obtained through Doppler measurements of the velocities of the Venera-13 and Venera-14 probes. The vertical distribution of the zonal component of wind velocity is presented, and variations of the radial component of the velocity of the descent module near the lower boundary of the cloud layer are examined. The general character of velocity variations is shown to be associated with atmospheric turbulence: appreciable variations having a characteristic time of 20 sec and greater and amplitudes greater than 0.7-1 m/sec were observed in the cloud layer; below 45 km, velocity variations did not exceed 0.3-0.5 m/sec.
