An air column at 60"n with ζ-0 initially stretches from the surface to a fixed tropopause at 10 km height. if the air column moves until it is over a mountain barrier 2.5 km high at 45 n, what is its absolute vorticity and relative vorticity as it passes the mountain top assuming that the flow satisfies the barotropic potential vorticity equation

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
