Qg height tendency
WebUsing the upper-air and surface maps provided, write a forecast discussion based on the QG Omega and QG Height tendency equations. Focus your discussion on the primary trough feature in the Western/Central U.S. Make sure you are covering each of the variables (omega and chi [height tendency]) for both equations in your discussion. WebWithin the QG framework, problems like those dis-cussed above can of course be avoided by using a di-agnostic tool that combines the vorticity and the ther-modynamic equation: the QG height tendency equation (Holton 1992, 159). In many cases, however, the nu-merous approximations in the QG theory itself hamper
