[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:*



Southwestern Côte d’Ivoire, central Nigeria, western Ethiopia, portions of
South Sudan, northeastern DRC, Uganda, southwestern Kenya and Madagascar
registered weekly rainfall totals of over 100 mm (moisture surpluses of
over 50 mm). In particular, the southwestern part of Côte d’Ivoire observed
moisture surpluses of over 200 mm.



Week-1 outlook shows an increased chance for above average rainfall over
southern Niger, northern Nigeria, southern Chad, parts of Uganda, South
Sudan, western Kenya and southwestern Ethiopia.





*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits  dominated large parts
of central and southern peninsular India, Korea, Japan, Thailand, and Papua
New Guinea. Above normal rainfall dominated southeastern China. Elsewhere,
the rainfall amounts received were mixed. For the past 30 days the rainfall
amounts received were quite mixed, and particularly deficient over India,
by as much as 37 % below normal over much of India, and southern China
bordering Burma and north eastward. However, southeastern China received
above normal rainfall, as well as large parts of Indonesia.



In this past week, over almost the whole region, the rainfall amounts were
below and much below normal. Due the delayed and now highly deficient
southwest summer monsoon rainfall over India, large parts of India are
suffering rom scorching heat and much below normal rainfall, bordering on
drought conditions. Major cities in southern India are even without
drinking water.   For the next two weeks, the NCEP GFS model forecasts
below normal rainfall for large parts of India, particularly southern
India, which is already experiencing near-record dry conditions. Below
normal rainfall is also forecast for parts of Indonesia.





*North American Monsoons:*



Below-average rainfall has been observed over portions of northwestern and
southern Mexico during the past week.



Rainfall accumulations over the past 30 days were near-average for much of
the core NAM region.



NCEP/GFS Forecasts call for below-average precipitation for portions of
northwestern Mexico during the next two weeks.
