Phase diagrams of strong MJOs occurring between December 2002 and February 2003, December 2003 and February 2004, December 2005 and February 2006, and December 2007 and February 2008. Colored points in the diagrams (representing sequential days) distinguish the different months. The sequential days trace anticlockwise circles around the origin, signifying eastward propagation of the MJO. Distance from the origin is proportional to MJO strength. The amplitude circle in the center of the diagram signifies one-standard-deviation MJO strength.
