you mean jet streams...or thermals?
The answer is Jetstream.
high temperatures
The speed of sound increases with altitude due to the decrease in air density. This means that at very high altitudes, where air density is lower, the speed of sound will be faster compared to at sea level.
different air pressure...
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.

Jet streams
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Because of less gravity in high altitude
well the air pressure decreases as you go higher up and so does the temperature due to the warm air expanding and cooling. so yes high altitude affects you anywhere
High altitude gives you less air, therefore a bit less power
Exactly!
Jet streams
high altitude chambers
yes, the higher the altitude the thinner the air, thus the less oxygen in the air.
The density of air reduces as height is gained.
