Monday December 17

The MJO is now in Phase 3. After moving rapidly eastward the system has now slowed, similarly to the previous 2 MJO's. It should reach Phase 4 by the end of the week.

The Australian continental heat lows have been apparent, and the monsoon should be initiated by the approach of the MJO in the tropics.

4th December

The MJO is now in Phase 8. Central Pacific Easterly wind anomlaies have weakened with the passage of the MJO. Westerlies trailing the MJO are apparent over the western Pacific.
Convection is now suppressed through the Maritime Continent region .

The next passage of the MJO should reach Phase 4 about the 22nd of December, or in 16-25 days - a few days later than I suggested last week.

There is a very good chance that the next passage of the MJO will coincide with Australian monsoon onset.
