Unformatted text preview: large summerwinter difference and a highlevel wind pattern is set up. Stratosphere and Lower Mesosphere There is believed to be a fairly simple global wind pattern in the 2050km height range. Looking at the Coriolis equation above, in summer northern hemisphere u<0 and phi > 0 so we expect dp/dy>0. In the winter hemisphere we get u>0 and phi < 0 so dp/dy > 0. Set u>0 and phi < 0 so dp/dy > 0. So, the pressure increases from winter to summer poles  a contract with ground level where the surface governs the heating, and we get maximum pressure from the maximum heating....
