GEOS 200 Lecture Notes - Lecture 7: Advection, Low-Pressure Area
Document Summary
Air is moved from one location to another. All forces in balance, the sum of net forces is equal to zero. No net motion, because they are in balance. At the same height, temperature and pressure at a are not equivalent to temperature and pressure at b. Lines of pressure are inclined with respect to each other. Lateral forces the motion will be directly in a straight line. High pressure area to the low pressure area. Net outcome: if i let this condition exist, it would overturn and mix all the air in here and. I would be back to a uniform state of mixture. Overturn it, mix it, return to common temperature and pressure when air is mixed. Change the temperature on the structures, air was set in motion, according to newton"s law. Mercury would drop lower in low pressure environment.
