Yes, the atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere.
The mass of the Venus atmosphere is about 90 times that of the Earth's atmosphere. 90% of the Earth's atmosphere is within 10 km of the surface, whereas you have to go to 50 km to capture 90% of the atmosphere of Venus. The clouds of Venus may extend from about 50 to 70 km and may be divided into three distinct layers. Below the clouds is a layer of haze down to about 30 km and below that it is clear.
Above the clouds there is a high-speed "jet stream" which blows from west to east at about 300-400 km/h. This wind is fastest at the equator and slows toward the poles, often giving a "V" type pattern in the visible cloud cover. At the surface there is almost no prevailing wind, with measured surface wind speeds typically less than 2 m/s.
What else can I help you with?
does air traffic affect the jet stream?
No, air traffic does not directly affect the jet stream. The jet stream is a high-altitude wind current caused by the rotation of the Earth and atmospheric pressure differences. While air traffic can contribute to localized weather patterns, it does not significantly impact the behavior or strength of the jet stream.
What determines how far south the the cold air from the north pole travels?
The jet stream
What is the difference between a continental jet stream and a polar jet stream?
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
What attaches itself to this jet stream and in sense tells you where the stratosphere bagins?
The tropopause is the boundary that attaches itself to the jet stream and indicates where the stratosphere begins. It acts as a transition layer between the troposphere, where weather occurs, and the stratosphere, which contains the ozone layer. The jet stream is typically found at the tropopause level, highlighting its role in separating these two atmospheric layers.
During which months is the jet stream located closest to the equator?
The jet stream is typically located closest to the equator during the winter months of December through February in the Northern Hemisphere. Conversely, in the Southern Hemisphere, it tends to be closer to the equator during June through August. Seasonal shifts in temperature and atmospheric pressure largely influence the position of the jet stream.

Which is stronger polar jet stream or subtropical jet stream?
The polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.

What are the two jet streams in the northern hemisphere?
mid latitude jet stream and jet stream
What weather word starts with J?
jet stream
Do jet stream occur in the mesosphere?
No. The jet stream is in the upper troposphere and lower stratosphere.
which is true of jet streams?
The polar jet stream is generally stronger than the subtropical jet stream
What is true about a jets stream?
The polar jet stream is generally stronger than the subtropical jet stream
What are atmospheric winds?
Unless you mean solar wind, you are likely referring to the jet stream, which can affect air travel arrival times and the smoothness of the trip.
