[Ncep.list.emc.monsoondesk] Weekly Updates of Global Monsoon Systems

[Wei Shi - NOAA Federal]

The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems have been updated on the CPC Global Monsoons
website:
http://www.cpc.ncep.noaa.gov/products/Global_Monsoons/Global-Monsoon.shtml

*HIGHLIGHTS:*



*African Monsoons (AFMS.ppt):*



Suppressed rainfall prevailed across much of the Gulf of Guinea region,
whereas moderate to locally heavy rainfall resulted in moisture surpluses
over much of the Greater Horn of Africa.



Week-1 outlook calls for an increased chance for below-average rainfall
over portions of Nigeria. In contrast, there is an increased chance for
above-average rainfall over Equatorial Guinea, Gabon, southern Cameroon,
Congo-Brazzaville, South Sudan, Ethiopia, Uganda, Kenya, and much of
Somalia.





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



For the past 90 days rainfall amounts are showing minor deficits across
southern India, and major deficits over large parts of Australia and
southeast Asian countries such as Thailand, Laos, and Cambodia, the
Philippines and eastern Papua New Guinea.  However, northeastern India,
coastal southeastern China and many parts of Indonesia received  above
normal rainfall. For the past 30 days the rainfall situation was deficient
over the Philippines islands, Thailand, Laos, Cambodia, Vietnam,
northwestern and southeastern Australia. The exception is over northeastern
India, southeastern China, and parts of Indonesia.



In this past week, rainfall was generally deficient across the region
except over the island of Borneo.  In the next couple of weeks the NCEP GFS
model is predicting above normal rainfall over eastern China, Indonesia,
and central Australia.





*South American Monsoons (SAMS.ppt):*



Long-term rainfall deficits continue over the Amazon Basin and central
Brazil. The rainy season has ended over central Brazil.



During the last 7 days (25 April-1 May 2016), below-average precipitation
was observed over most of the Amazon Basin and northern Northeast
Brazil.  Above-average
precipitation was observed over portions of southern and southeastern
Brazil, central Colombia, parts of Venezuela and most of Suriname, Guyana
and French Guiana.



For  2-8 May 2016, below-average precipitation is predicted for most of the
Amazon Basin in Brazil, northern Peru, extreme southern Brazil, Uruguay and
the southern half of Chile. Above-average precipitation is predicted for
scattered portions in northern South America.
