Japan’s Venus orbiter Akatsuki has discovered a previously unseen equatorial jet with wind speeds that often exceed 200 miles per hour.
The winds, named “equatorial jet” by the research team, were found from July to August 2016 when an infrared camera captured images of areas about 45 to 60 kilometers above the planet’s surface. The areas are invisible at optical wavelengths due to extremely dense clouds of sulfuric acid. The camera spotted thick clouds traveling at a speed of 288 kph to 324 kph near the planet’s equator.
Based on the news reports, it appears the significance of this discovery is that they identified a particular jet stream at a specific latitude. Previous observations did not have that resolution.
This would have been posted in the morning, but the internet access here in this Torrey hotel is almost as slow as what I experienced in Glacier. I had it written, but I sinply couldn’t get it to post this morning.
