Less Saharan Air Layer in Atlantic
http://cimss.ssec.wisc.edu/tropic/real- ... split.html
All the corridor between Africa and the Lesser Antilles is void of sal south of 15n.This is the first time this year that the data shows this indicating more moist air in the MDR area.

I've had to Wiki it too!
The MJO is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian Ocean and Pacific Ocean. The anomalous rainfall is usually first evident over the western Indian Ocean, and remains evident as it propagates over the very warm ocean waters of the western and central tropical Pacific. This pattern of tropical rainfall then generally becomes very nondescript as it moves over the cooler ocean waters of the eastern Pacific but reappears over the tropical Atlantic and Indian Ocean. The wet phase of enhanced convection and precipitation is followed by a dry phase where convection is suppressed. Each cycle lasts approximately 30-60 days.
The MJO is also known as the 30-60 day oscillation, 30-60 day wave, or intraseasonal oscillation.
Although tropical cyclones occur throughout the boreal warm season (typically May-November) in both the Pacific and the Atlantic basins, in any given year there are periods of enhanced/suppressed activity within the season. There is evidence that the MJO modulates this activity (particularly for the strongest storms) by providing a large-scale environment that is favorable (or unfavorable) for development. The strongest tropical cyclones tend to develop when the MJO favors enhanced precipitation. As the MJO progresses eastward, the favored region for tropical cyclone activity also shifts eastward from the western Pacific to the eastern Pacific and finally to the Atlantic basin. While this relationship appears robust, the MJO is one of many factors that contribute to the development of tropical cyclones. For example, it is well known that sea surface temperatures must be sufficiently warm and vertical wind shear must be sufficiently weak for tropical disturbances to form and persist.

No wonder I didn't saw your thread as it was already on page 3.But we agree that time will come soon for things to pick up.
