Teleconnection patterns associated with MJO phase 1

MJO phase 1 pentad composites of anomalous 250-hPa geopotential height, where
a pentad denotes a 5-lag mean, or the field average of lags 0 - 4 following an MJO
phase. Positive geopotential height anomalies are in red solid contours, and negative
anomalies are in blue dashed contours. Contours are every 10 m, and the zero contour
is omitted. Anomalies found to be 95% significantly different from zero are dotted.
The color shading shows the anomalous tropical precipitation composite during MJO
phase 1.
