[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:*



Above-average rainfall was observed over many places in the Gulf of Guinea
and Central Africa countries.



Week-1 outlooks call for an increased chance for below-average rainfall
over much of Senegal, Gambia, Guinea-Bissau, northern Guinea, southern
Mauritania and southwestern Mali. In contrast, there is an increased chance
for above-average rainfall across eastern Burkina Faso, northern Togo,
northern Benin, southwestern Niger, central and northern Nigeria, northern
Cameroon, northern CAR, and western Sudan.



*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits  dominated
northeastern China, and all over India except the northeast and the
Gangetic Plains and along the northern slopes of the Western Ghats,
southeastern China, and near Vietnam, Laos and parts of Cambodia. For the
past 30 days the rainfall amounts received were below normal over southern
peninsular India, but above normal along the Gangetic plains and the
northeast and over Burma as well. Many parts of Indonesia, Thailand,
northeastern China and Korea experienced below normal rainfall.



In this past week, over almost the whole region, the rainfall amounts were
slightly better across much of India, while the reverse was true over
eastern China. As of today since the first of June, the India Met. Dept.
reported that the overall All India Monsson Rainfall amounts were 12% below
the long term mean. For the next two weeks, the NCEP GFS model forecasts
continued below normal rainfall for southeastern peninsular India,
southeastern China, and many parts of Indonesia. Elsewhere, in general,
above normal rainfall is forecasted.



*North American Monsoons:*



Near-average rainfall has been observed over southwestern US during the
past 7 days, while northwestern Mexico experienced drier-than-average
conditions.



Rainfall accumulations over the past 30 days were below-average for much of
Mexico and southwestern US.



NCEP/GFS Forecasts call for near-average precipitation for much of the
southwestern US and northwestern Mexico during the next two weeks.
