weatherwiz Posted March 7, 2016 Share Posted March 7, 2016 I've been heavily searching around for some papers and have found a few and I signed up for an account n WDT which provides access to AMM/GWO plots and such but are there any links where you can create reanalysis plots and such? What I'm trying to do is learn and understand what influences on the atmosphere pattern and jet stream say like +/- occurrences of mountain torque have along with +/- episodes of AAM and such.

Paulie21 Posted March 8, 2016 Share Posted March 8, 2016 Victor Gensini wrote a lot about that, I recommend reading his paper on the topic. When you plot global relative angular momentum and the first time derivative on a phase space you acquire the global wind oscillation. This accounts for changes in the global budget of angular momentum through interactions of sfc/mountain torque and different convection anomalies in the tropics.http://www.esrl.noaa.gov/psd/map/clim/gwo_phase_fig4.jpgI won't spoil the paper for you because it's absolutely fascinating but phase 5 implies a retracted pacific ocean jet stream, which also implies a western CONUS trough. As you get to latter stages, angular momentum is positive, negative AM is being removed from friction and mountains and not nearly as favorable for that western trough. There is a site or two where the GEFS plots a two week forecast for the global wind oscillation, however, I am not sure if I am allowed to link that.
