Atmospheric Variability Diagnostics — CAM5.control.FAMIPC5.f19.1990-2005.MJO
Wheeler-Kiladis spectra + CLIVAR-MJO suite (lag cross-correlation, combined EOF,
composite life cycle, seasonal wavenumber-frequency). Daily/6-hourly model output; anomalies =
smoothed-climatology removed, 20-100 day band-pass. Obs reference = ERA-Interim
(US-CLIVAR MJO-suite / MDTF digest) for OLR & winds + TRMM for precip, now shown
alongside a period-matched ERA5 (1991-2005) column (green accent) processed through the
official mjoclivar suite.

1. Lag cross-correlation (IO precip base; lag-lon top, lag-lat bottom)
Eastward tilt = eastward MJO propagation; precip (color), U850 (contours).

2. EOF analysis of OLR / U850 / U200 (15S-15N)
Top: combined multivariate EOF1 & EOF2 (the MJO mode pair, longitudinal structure). Below: per-variable seasonal EOF spatial maps — model vs ERA.

3. Composite life cycle (8 MJO phases; OLR anom + 850-hPa wind)
Rows = 8 MJO phases; OLR anomaly (color) + 850-hPa wind (vectors); days with MJO index > 1. Model paired with the ERA-Interim composite for each season. The Nov-Apr (boreal-winter) life cycle is the canonical MJO season — an eastward-marching dipole from the Indian Ocean (P1-3) into the Maritime Continent / West Pacific (P4-7) signals a realistic MJO.
