MJO composites for different seasons

Composites are formed by averaging/accumulating the field data for 8 different phases of the MJO. The 8 phases are defined by the position of the (RMM1,RMM2) point within the 2-dimensional phase space as shown here. The methods used to produce these composites are described in the paper Wheeler et al. (2008).
