Question

1) The atmospheric jet stream is a zonal flow of the upper troposphere, which plays a central role in midlatitude weather. If we ignore the variations in air density, we can model the average jet stream as a purely zonal flow, independent of height and varying meridionally according to 2L in which the constants Uo and L are taken as 40 m/s and 570 km, respectively. If the jet center (y-0) is at 45 N on a ß-plane, is the jet stream stable or unstable?
