High altitude rivers of air are fast-moving narrow bands of strong winds in the upper atmosphere known as jet streams. They flow from west to east and can have a significant impact on weather patterns and aviation routes. These high altitude winds play a crucial role in steering weather systems and influencing the movement of storms.

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
