The following plots are derived from the GEOS-5 0.67 x 0.5 gridded analyses and forecast. Details on GEOS-5. GEOS-5 is a comprehensive assilation system that is a product of the NASA GSFC Goddard Modeling and Assimilation Office.
The model analyses are filtered to expose traveling waves.
The plots are set up for ROAH 26.2126N, 127.6790E and KSLN 38.7787N, 97.6396W
The plots show the zonal mean temperatures from the GEOS-5 analyses and forecasts. Usually the forecasts are separated from the analyses by a line.

Two digital filters are used to isolate the wave propagation.
Low Pass is designed to filter
all wave with periods greater than 20 days. The 1/2 amplitude response is set to 20 days.
Band Pass is designed to filter
waves between 1 and 20 days. The 1/2 amplitude response is set to 20 days and 1 day.
