AMWG Variability Test Plots

AMWG Variability Diagnostics for Daily Data

Intraseasonal Variability

Daily 200 hPa velocity potential anomalies computed and then averaged
over 5S-5N, 20-70 day bandpass filter then applied. Hovmöller plots.

Madden-Julian Oscillation
Time series of daily 200 hPa zonal wind averaged over 10N-10S.
200 hPa zonal wind bandpass filtered for 20-100 day period.
MJO Index defined as the running variance of the bandpass filtered data.
