[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:

*HIGHLIGHTS:*



*African Monsoons:*



Above-average rainfall was observed portions of DRC and South Sudan, and
coastal East Africa. Portions of Ghana and Burkina Faso also received
above-average rainfall.



Week-1 outlooks call for an increased chance for above-average rainfall
over portions of DRC and Ethiopia, and northern Somalia. In contrast there
is an increased chance for below-average rainfall over portions of South
Sudan, southern Somalia and Kenya.





*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits  dominated deep
southern coastal peninsular India, Korea, Japan, Thailand, Malaysia, the
Philippines, parts of New Guinea island of Indonesia and Papua New Guinea,
and almost all of Australia, particularly coastal north western regions.
Elsewhere, the rainfall amounts received were at normal to slightly above
normal levels, particularly in southeastern China,  parts of the Middle
East and Indonesia. For the past 30 days near normal rainfall fell across
the Middle East and across  entire Australia coast and vicinity,. Elsewhere
the rainfall amounts received were mixed. Below normal occurred over
Koreas, Japan, Thailand, Malaysia, the Philippines, and Papua New Guinea.



In this past week, over almost the whole region, the rainfall amounts
received were below normal. For the next two weeks, the NCEP GFS model
forecasts overall less rainfall across the region, especially over
southeastern China.





*South American Monsoons:*



Long-term rainfall deficits are present over the western Brazilian Plateau.



During the last 7 days, below-average precipitation was observed over
portions of northern Brazil, southern Chile and northeastern Peru.
Above-average precipitation was observed over portions of the extreme
southern Brazil, Paraguay, northeastern Argentina and central Colombia.



For Days 1-7 (13 - 19 May 2019), below-average precipitation is predicted
over much of northeastern South America, as well as portions of
west-central and southern Brazil, Bolivia, northern and southern Peru and
southern Chile. Above-average precipitation is predicted for portions of
northwestern and east-central Brazil and much of Ecuador and southern
Colombia.
