Because...
“But those clouds are moving fast. The winds on Venus are powerful, circulating around the planet in just a matter of days. But because of Venus’ high temperatures and intense atmospheric pressure, they don’t behave like the winds on other planets.”
Our winds are not as dramatic because our planet rotates.
Yes, but it is wrong to say Venus doesn't rotate. Because if it didn't rotate the entire circumference would in time receive direct sunlight as the planet orbited the sun.
Below: imagine the blue earth in the center is the sun, and the gray moon is Venus. Red and green dots indicate a fixed position on the planet (Venus).
This is only true for the winds at higher elevations. Surface winds are weak. Only a few miles per hour.
