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.
