This shows SST and surface
air tem anom. during 1999/2000 winter. A strong La Nina occurred in the EP
with warm signals in North and South Pacific. USA experienced long-lasting
warm winter. This can be predicted at 18 and 24 months ahead. Besides, the cold
signals in SA, AU, Asia, large parts of Africa, and the warm signal in
Northern Eurasia are also predicted. This year, another strong La Nina
appeared. The model predicted that it would be long-lived. And you may expect
the similar pattern this winter.
