Design of Hindcast Experiments

(1) Experimental Type

• HFP 1: Two-tier prediction forced by SNU SST forecast (Kug et al. 2007)
• HFP 2: One-tier prediction using CGCM
• HFP 3: Two-tier prediction forced by SST forecast anomaly of one tier system plus observed SST climatology

(2) Experimental Period

• 24 years of 1981-2004 for four initial conditions which are Feb 1, May 1, Aug 1, and Nov 1 for targeting spring, summer, fall, and winter seasonal prediction, respectively.

(3) Variables

• Monthly mean data: total precipitation rate, surface (2m) air temperature, sea surface temperature, mean sea level pressure, geopotential heights at 500 hPa, horizontal wind fields (u and v) at 850 and 200 hPa and stream function and velocity potential at 850 and 200 hPa,
• Daily mean data: total precipitation rate, surface (2m) air temperature, horizontal wind field at 850 and 200 hPa.

Currently Available Data

The 7 two-tier and 7 one-tier hindcasts are available mostly for 24 years of 1981-2004.
