The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems (SAMS.ppt, AFMS.ppt and AAMS.ppt) have been
updated on the CPC Global Monsoons website:


*African Monsoons (AFMS.ppt):*

Weekly total rainfall exceeded 120mm over local areas in northern Malawi,
southern Tanzania and northern Madagascar.

Suppressed rainfall continued to prevail over many places of the Central
and southern African countries.

Week-1 outlooks call for an increased chance for above-average rainfall
over southern Angola, portions of southern DRC, central and eastern Zambia,
Malawi and northern Mozambique. In contrast, there an increased chance for
below-average rainfall over southern Zimbabwe, northern South Africa,
central and southern Mozambique, and southern Madagascar.

*Asian-Australian Monsoons (AAMS.ppt):*

For the past 90 days, the rainfall over southern India has been below
normal, whereas it was above normal over much of Malaysia, Indonesia,
northwestern Australia and Philippines. Rainfall was also below normal over
Papa New Guinea and over Queensland. For the past 30 days, rainfall over
the region as a whole in general has been at or above normal levels, except
over eastern China and Papa New Guinea. Northwestern Australia had excess
rainfall in the past 30 days.

In this past week, more or less the entire region, particularly northern
Australia received below normal rainfall. In the next two weeks, the NCEP
GFS model is predicting near to above normal rainfall over Indonesia and
vicinity, but below normal rainfall over Australia, especially Queensland.

*South American Monsoons (SAMS.ppt):*

Rainfall deficits continue over central and southeastern Brazil.

During the last 7 days (19-25 January 2015), below-average precipitation
was observed over central and southeastern Brazil.  Above-average
precipitation was observed over portions of Colombia, Ecuador, northern
Peru and northern Bolivia.

For 26 January-1 February 2015, below-average precipitation is indicated f
or most of Brazil from the equator to 20S, northern Argentina, Uruguay and
extreme southern Brazil. Above-average precipitation is predicted for
southern Colombia and northern Peru.
