This case study covers events related to the Madden-Julian Oscillation and equatorial waves in May 2002 over the Indian Ocean basin (see graphic below). It will show you how to monitor the MJO and equatorial waves using satellite data and observational analyses and how to assess the potential for tropical cyclone development based on MJO and equatorial wave interactions. You will also see how to use your analyses to forecast expected weather hazards in the regions affected by these tropical features.
