[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 over many places in East Africa, and
portions of Southern Africa.



Week-1 outlooks call for an increased chance for below-average rainfall
over southeastern Gabon, Cong-Brazzaville, western DRC, Angola, southern
Malawi, parts of eastern Zimbabwe and Mozambique. In contrast, there is an
increased chance for above-average rainfall over parts of eastern DRC,
Rwanda, Burundi, southern Uganda, southwestern Kenya, much of Tanzania, and
northeastern Zambia.



*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits remain over
Afghanistan, along the east coast of India bordering the Bay of Bengal,
Papua New Guinea, and over the eastern two thirds of Australia especially
in the northern parts therein. Elsewhere small broken pockets of below
normal precip regions remain. However, over Indonesia, the Philippine
islands, Malaysia, and over the south China Sea region countries such as
Vietnam, Cambodia, Laos and Thailand the precip is at above normal to near
normal levels. For the past 30 days,  rainfall amounts were generally at
near or slightly above normal levels across the region, except over  Papua
New Guinea, southeastern China, and over northwestern Australia. Western
Australia got its monthly rainfall amounts for the period.



In this past week, rainfall anomalies over the region were generally weak,
with slightly above normal rainfall over east central Australia and below
normal rainfall over northwestern parts of the continent. In the upcoming
two weeks, the NCEP GFS model is predicting a mixed rainfall pattern over
the region with some relief in sight for some parts of the drought region
in east central Australia, and continued below normal for southeastern
China.



*South American Monsoons:*



Long-term rainfall deficits are present over the Amazon Basin and the
Brazilian Plateau.



During the last 7 days, below-average precipitation was observed over much
of northern and central Brazil, Uruguay, eastern Argentina, southern
Bolivia, Ecuador and western Colombia. Above-average precipitation was
observed over portions of eastern and southern Brazil, Paraguay and
northern Peru.



For Days 1-7 (05 - 11 Mar 2018), below-average precipitation is predicted
over much of northern and southern Brazil, Uruguay, eastern Argentina,
eastern Bolivia and Ecuador. Above-average precipitation is predicted for
portions of northern Venezuela, central-eastern Brazil, Paraguay and Peru.
