MJO structure over Indian Ocean (used as refrence for the later analysis)

  1. Lon-lag composites and regressed eastward 20-90 days filtered uwind, sh, and OLR against PC1 : ERAI25
  2. Lon-lev composite of eastward 20-90 days zonal wind against PC1: ERAI25
  3. Lon-lag composite of eastward 20-90 days u850 against PC1 at varying q: ERAI25
P.S. PC1 is based on the 20-90 days filtered OLR.
