Consider an opened container filled with an incompressible fluid. Let the total H be the height of the container, h is the depth, and z is the height. If one is to analyze the vertical pressure variation of the atmosphere of Earth, the length scale is very significant (troposphere alone being several kilometres tall; thermosphere being several hundred kilometres) and the involved fluid (air) is compressible. Gravity can still be reasonably approximated as constant, because length scales on the order of kilometres are still small in comparison to Earth's radius, which is on average about 6371 km, and gravity is a function of di… cum ajung la thermeWebAir moves from areas of high pressure to areas of low pressure. Also, if areas of different pressures are closer to eachother (close isobars), the wind velocity is higher and if the areas span over a larger area of land (far isobars), the wind is slowed down because i undergoes lots of friction and builds up over more land and it takes more energy to move … east penn manufacturing co

In this paper, we identified an energy transmission mechanism that occurs in the atmosphere, but which up until now seems to have been overlooked. We call this mechanism “pervection”. Pervection involves the transmission of energy through the atmosphere, without the atmosphere itself moving.
