Climate in-brief
Moisture levels and cloudiness remains high to Australia’s north with the Northern Coral Sea very warm, albeit with MJO forecast to appear in the Indian Ocean, away from Australia in the coming week.
Very little in the way of cyclone activity expected in the coming fortnight, as waters cool to Australia’s north
The Southern Annular Mode is maintaining its good form in moderately positive (wet) phase and predicted to remain so, - assisting moisture flow through NSW and S Qld areas.
Multi-week models showing split fortunes for tropics and mid-latitudes, with some caution for large areas of Qld through January. On the other hand, consensus shows continued moisture for much if NSW and SE Qld over the coming 4 weeks.
Temperatures to remain around normal or cooler throughout January, consistent with increased cloud cover and influence of the current La Nina.
The chart above shows higher-than-normal air pressure in Southern Australia for the last 30-days and lower air pressure to the NW.
