2 Precipitation is a strong increasing, non-linear function of lower free tropospheric humidity Diabatic heating profile result of integrated effects of cloud population and radiation Diabatic heating structure influences large-scale circulation response Large-scale circulation response alters moisture field MJO ????

9 0°0° 90° 180° 270° each gridpoint has its own “phase” gridpoint phase

10 0°0° 90° 180° 270° corresponds to RMM phase of maximum (+) MJO related anomaly in a variable gridpoint phase RMM phase EX: for zonal wind this corresponds to maximum westerly winds

11 0°0° 90° 180° 270° corresponds to RMM phase of maximum (-) MJO related anomaly in a variable gridpoint phase RMM phase EX: for zonal wind this corresponds to maximum easterly winds

12 0°0° 90° 180° 270° Tells you where you are in MJO lifecycle gridpoint phase RMM phase 45°prior to maximum (+) anomaly

13 0°0° 90° 180° 270° Tells you where you are in MJO lifecycle gridpoint phase RMM phase 45°after maximum (+) anomaly

14 Identifies at what “RMM” phase maximizes at each location Objectively calculated from EOF structure DYNAMO TOGA-COARE
