Аннотация
Vertical temperature and pressure profiles in the atmosphere of Venus obtained by the radio occultation (RO) method using the Venera-15 and -16 spacecraft measurements made from October 1983 to September 1984 are used for a wind speed analysis. The altitude and latitude profiles of a zonal wind speed in the middle atmosphere for Northern and Southern hemispheres of planet at altitudes from 50 to 80 km and in the latitude interval from 60° to 85° have been found. Zonal wind speeds were determined assuming cyclostrophic balance. The jet with a maximum wind speed ~100 m/s located at an altitude of ~60 km and latitudes 73°–75°N is shown to exist in the Northern near-polar atmosphere. Above an altitude level of 65 km in the Northern hemisphere, the polar atmosphere is warmer than the near-polar one and a wind speed usually decreases with increasing altitude at these levels. The wind speed determination results at Southern latitudes show clearly the presence of the jet with a maximum speed of ~115 m/s located at an altitude of ~62 km and latitudes 70°–72°S. These high-latitude jets are due to by the negative latitude-temperature gradients at altitudes below jet axes in the near-polar atmosphere.
