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.
Bandpass filter response plot

cesm1.5_F2000_f09f09_alpha06_cntlexp06_016s. Anomalies are relative to the 0001-0002 mean.
1-2

Anomalies computed relative to the time period mean.

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.
