Birders interested in the La Nina pattern bringing vagrants and floods
to much of Australia might like to have a look at a graphic released
by the US National Oceanic and Atmospheric Administration (NOAA) - http://www.noaanews.noaa.gov/stories2011/20110112_globalstats.html
. It clearly shows a cool anomaly in the eastern Pacific and a warm
anomaly in the western Pacific.
Overall, warm anomalies greatly outnumber cool anomalies.
The greatest marine anomalies were in the central Atlantic [associated
with a strong hurricane season]. Interestingly there is a cold
anomaly for much of the Southern Ocean.
Over land, the greatest warm anomalies were over Canada, Greenland,
North Africa, Central Asia and Eastern Siberia. The only areas with
large cool anomalies were central Siberia and Scandinavia.
