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):*

Another week of heavy rainfall sustained moisture surpluses across eastern
Zambia, Malawi, northern Mozambique, southern Tanzania and Madagascar.

Suppressed rainfall continued to prevail over much of the Central and
Southern Africa countries.

Week-1 outlooks call for an increased chance for below-average rainfall
over Equatorial Guinea, Gabon, Congo-Brazzaville, much of DRC, northern
Angola, Botswana and Zimbabwe. In contrast, there is an increased chance
for above-average rainfall over eastern Zambia, much of Malawi, southern
Tanzania, Mozambique and Madagascar.

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

For the past 90 days, the rainfall over south and southeast Asia has been a
mixed bag. Southern India, northeast India, Cambodia, Laos, Vietnam,
eastern Indonesia, New Guinea, eastern Australia particularly Queensland
have been below normal, whereas other parts of  the region have been at or
above normal particularly northwest Australia. 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, Papa New Guinea, and Queensland.
Northwestern Australia had excess rainfall in past 30 days.

In this past week, above normal rainfall was centered over eastern Burma
and nearby southwestern China. A strong low pressure center  over western
Australia brought copious rainfall for the region. In the next weeks, the
NCEP GFS model is predicting above normal rainfall to parts of Indonesian
islands and northern Australia.

*South American Monsoons (SAMS.ppt):*

Rainfall deficits increased over the southern Amazon Basin, and central  and
southeastern Brazil.

During the last 7 days (5-11 January 2015), below-average precipitation was
observed over the central and eastern Amazon Basin, and central and
southeastern Brazil.  Above-average precipitation was observed over
portions of southern Brazil, Uruguay and northeastern Argentina.

For 12-18 January 2015, below-average precipitation is indicated for most
of Brazil. Above-average precipitation is predicted for extreme southern
and western Brazil, and northeastern Argentina.
