Stratospheric Seasonal Evolution Plots

Stratospheric Seasonal Evolution Plots


The meteorological data shown here are derived from the NASA Goddard Global Modeling and Assimilation Office (GMAO) GEOS-5 data assimilation and forecast system. The NASA GSFC GEOS-5 model is run at a 0.3125 degree longitude and 0.25 degree latitude resolution with vertical levels at the standard pressure levels. The model data are at 6h intervals (0, 6, 12, and 18Z). The GEOS-5 Wiki page contains the main details on this data.

The plots are all 2-panel. The RHS plot shows the 60-day time-mean profile of the quantity, while the LHS shows the deviations from this 60-day mean.


1. Temperature

The 6h temperature data are low pass filtered with a Gaussian filter that has a 1/2 amplitude response at1 day.

    3. Eddy heat flux (EHF) plots

    These plots are scaled with the square root of pressure to make the tropospheric values more visible. The 6h EHF data are low pass filtered with a Gaussian filter to make them more readable. The filter has a 1/2 amplitude response at 1.66 days.

  • Eddy Heat flux vs. pressure
  • 80S-30S 30N-80N

    B. Eddy heat flux vs. latitude

    4. Eddy momentum flux (EMF) plots

    These plots are scaled with the square root of pressure to make the tropospheric values more visible. The 6h EMF data are low pass filtered with a Gaussian filter to make them more readable. The filter has a 1/2 amplitude response at 1.66 days.
