The figure shows our latest forecast using a neural network model trained with data up to May 1999. The four panels are for 3-, 6-, 9-month and 12-month leadtimes respectively. The black line is the observed SSTA (in degree Celsius), and the blue circles are forecasts.
Figure 1 shows the forecasts at leadtimes of 3, 6, 9, and 12-months, using data up to May 1999. Forecasts of all 4 leadtimes indicate that current La Nina conditions in the tropical Pacific will continue into the 1999/2000 winter. Our model has been consistently calling for a La Nina 1999/2000 winter since January 1999 .
