Like with Jupiter, maybe regional zones... striations that have separated out... like Horse Latitudes, or Calm Zones....perhaps... just my take... I think they separate because of Rotation... but that is just my conjecture.

It is very good that the Japanese probe Akastuki is studying it.

<<It is believed that the phrase “better late than never” is a direct translation of a Latin proverb. It was first recorded as “potiusque sero quam nunquam” by Titus Livy in his “History of Rome.” The phrase found its way into English later. How this happened is unknown. It could have been translated from Latin works or become part of everyday vernacular in Latin and passed on as languages changed.

Geoffrey Chaucer used a variation of the phrase in his “Canterbury Tales.” The phrase appears in the “Canon’s Yeoman’s Tale.” Both characters are absent from the prologue and join the merry band at a later date as they make their way to Canterbury. Both are portrayed as alchemists, and Chaucer’s distaste for both is clear to see. The phrase does not relate to their late arrival, but to what actions should be taken. The full line is: “Ye that it usen, I counsel ye it let, lest ye lose al; for bet than never is late; never to thrive, were too long a date.” Chaucer is basically saying that never is too long an amount of time for something to thrive, but to be late is not. His form of this phrase is written as “for bet than never is late.”

“Better late than never” can be used as both an excuse and a terse denunciation for tardiness. If a student arrives late at a lecture or hands an essay in late, the professor may utter such a phrase. The cheeky student may also make a stab at humor by using it. The proverb is also related to “it’s never too late,” which is to say that it is never too late to stop something or to try something. To stop smoking later in life is “better late than never,” as is finding the time to explore new musical types, travel the world or get to grips with Woody Allen films. This does not mean such things are necessarily better later in life.>>

Does this photo show differences in heat within the surface layer of visible clouds that we see optically, or are we seeing heat differences that are present below the visible surface and deeper in the atmosphere. If deeper, then how far down is it?

<<A tourist highway or holiday route is a road which is marketed as particularly suited for tourists. Tourist highways may be formed when existing roads are promoted with traffic signs and advertising material. Some tourist highways such as the Blue Ridge Parkway are built especially for tourism purposes. Others may be roadways enjoyed by local citizens in areas of unique or exceptional natural beauty. Still others, such as the Lincoln Highway in Illinois are former main roads, only designated as "scenic" after most traffic bypasses them. In the USA this type of roadway is commonly termed a scenic highway. In Europe and other countries around the world they are often marked with brown tourist signs with the individual route symbol and/or name.>>

Akatsuki is in a near equatorial orbit and won't see the poles for another two years

The Wiki article said, "A follow-up thruster burn on 26 March 2016, lowered Akatsuki's peak altitude of its orbit to about 330,000 km (210,000 mi) and shorten its orbital period from 13 to 9 days."

Will it perhaps see the poles sooner than 2 years?

By my calculation,
the specific impulse necessary to get to Venus is only about 86% that needed to get to Mars.

And a manned flyby could do a round trip to Venus in just 0.80 years ( :!: )
rather than a tedious 1.42 years for a round trip to Mars
(with lots more solar power for their creature comforts).

A manned flyby of Venus seems even more useless than a manned landing on Mars.
