The period of the oscillation varies between about 30 and 50 days, and appears to represent an eastward propagating disturbance with a phase speed of only about 8 m s-1. MJO has a great deal of impact on weather systems around the globe. Among others, the MJO may influence the variability of rainfall in the west coast of North America, affect the Indian monsoon development, and modulate the frequency and intensity of hurricanes in the Pacific Ocean and Caribbean Sea. For these reasons, the MJO is regarded as a forecast tool with great potential. The possible effect of the topography and land–sea contrast on the ...
