The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems have been updated on the CPC Global Monsoons


*African Monsoons:*

Suppressed rainfall prevailed over many places in Angola, southern DRC,
Uganda, Tanzania and Madagascar.

Week-1 outlooks call for an increased chance for above-average rainfall
over portions of Ethiopia, southwestern Angola and northwestern Namibia,
southern Zambia, Zimbabwe, and portions of Mozambique. In contrast, there
is an increased chance for below-average rainfall over portions of Tanzania
and northern Mozambique.

*Asian-Australian Monsoons:*

For the past 90 days, slight rainfall deficits remain over parts of central
eastern and eastern coastal India, but severe rainfall deficits are
established over  Papua New Guinea, and over large parts of southern
central, northeastern and eastern Australia. Elsewhere, the rainfall is at
above normal levels over much of the region, especially eastern China, the
Philippines and large parts of Indonesia.  For the past 30 days the
rainfall was  above normal over parts of eastern Afghanistan, Pakistan,
Jammu Kashmir region. Southern India, particularly the state of Tamilnadu,
the region of earlier rainfall deficits, received normal rainfall amounts
in the past 30 days. However, rainfall was below normal over eastern China,
northeastern and eastern Australia, and Papua New Guinea.

In this past week,  overall less than normal rainfall fell across the
region, except over western Australia, where the amounts were greater than
normal. In the next couple of weeks the NCEP GFS model is predicting a
mixed rainfall pattern, with surprisingly slightly more rainfall than
normal over parts of the middle east.

*South American Monsoons:*

Long-term rainfall deficits are present over the Amazon Basin and central

During the last 7 days (06-12 Feb 2017), below-average precipitation was
observed over portions of western and southern Brazil, western Bolivia,
Uruguay and southern Chile.  Above-average precipitation was observed over
much of central Brazil, Paraguay and northern Argentina.

For 13-19 Feb 2017, below-average precipitation is predicted over
northwestern and southeastern Brazil, northern Argentina, western Peru and
much of Colombia.  Above-average precipitation is predicted for portions of
northeastern Brazil, Uruguay and southern Chile.
