Experimental NOAA/ESRL PSD and CIRES/CDC Forecast of PDO in Pacific Domain
PDO Index Predictions (blue line) for 12 months, based on August-September-October 2009 initial conditions. Dotted lines indicate one standart deviation confidence interval, estimated from seasonally varying stochastic forcing. ( on the left). The time series units are degrees C. For typical values, the PDO timeseries can be divided by sqrt(N), where N = 125 is the number of grid boxes in the geographical domain. Comparison of PDO predictions errors: RMS errors vs lead time for LIM ( blue line), AR1 (red line) and a persistence forecast ( black line). ( on the right).
