Earth has a magnetic field and Venus does not -- a crucial distinction when assessing the effects of the sun on each planet.
As the solar wind rushes outward from the sun at nearly a million miles per hour, it is stopped about 44,000 miles away from Earth when it collides with the giant magnetic envelope that surrounds the planet called the magnetosphere. Most of the solar wind flows around the magnetosphere, but in certain circumstances it can enter the magnetosphere to create a variety of dynamic space weather effects on Earth. Venus has no such protective shield, but it is still an immovable rock surrounded by an atmosphere that disrupts and interacts with the solar wind, causing interesting space weather effects.
A recent study, appearing online in the Journal of Geophysical Research on February 29, 2012, has found clear evidence on Venus for a type of space weather outburst quite common at Earth, called a hot flow anomaly. These anomalies, also known as HFAs, cause a temporary reversal of the solar wind that normally moves past a planet. An HFA surge causes the material to flood backward, says David Sibeck, a scientist at NASA's Goddard Space Flight Center in Greenbelt, Md., who studies HFAs at Earth and is a co-author on the paper.

When discontinuities in the solar wind remain in contact with a planet's bow shock, they can collect a pool of hot particles that becomes a hot flow anomaly (HFA). An HFA on Venus most likely acts like a vacuum, pulling up parts of the planet’s atmosphere. Credit: NASA/Collinson
Maybe a climate ping, dunno.

I assume you have this contingency covered ...
Good thing there was an extra day in February this year.
Why isn't the solar wind coming from the same direction as the sunlight?!

Moderator! Moderator! SunkenCiv is posting dirty space pictures again!
Wow! That's rather evocative.
And here I've been thinking of Venus as feminine.
Anyway, I suspect this doesn't do very much to the conditions at fifty kilometers altitude, where the settlements will be. (Cloud-cities, if you will. R Buckminster Fuller will be so proud.)

Climate on Earth depends on latitude.
Climate on Venus depends on altitude.

Behold the power of transposed letters!
Climate on Venus depends on altitude.
Climate on FR depends on attitude.
Cute poem. Stock rotation indeed...
The pic should be of Venus’ pole (either one), but clearly they weren’t too worried about it. :’)
;’)
All I have to do is whisper “hot flow anomaly” and the girls swoon.
Now, *that’s* bow shock.
Our government at work!
People here who think NASA is any different from any other agency of incompetents should pay attention.
