Model experiments. CAM4.0 was run for 10 years without any forcing at 1deg resolution - the control run (data ocean ). Each of the forced experiments were run for 135 days.
Forced Signals (Idealized)
Multichannel singular spectrum (MSSA) has been used to identify the temporal variability and to determine the coherent intraseasonal space-time patterns for different variables.
The 45 day period oscillation is studied, which also captures the MJO.
