| 内容記述 | Images of the Venus nightside recently acquired at wavelengths near 1.74 and 2.3 microns, in narrow atmospheric windows between the CO2 and H2O bands, allow the identification of mechanisms responsible for bright contrast figures moving from east to west in the direction of the cloud-top atmospheric superrotation. The 6.5-day east-west rotation period of the features indicates equatorial wind speeds of the order of 70 m/sec in this upper layer. The bright features are indicative of partial clearings in the cloud deck which could decrease the efficiency of the atmospheric greenhouse maintaining the high surface temperatures of Venus. |
