Use of Data to Improve Seasonal-to-Interannual Forecasts Simulated by Intermediate Coupled Models
This paper provides a detailed illustration that it can be much more beneficial for ENSO forecasting to use data to improve the model parameterizations rather than to modify the initial conditions to gain in consistency with the simulated coupled system.

ENSO Simulated by Intermediate Coupled Models and Evaluated with Observations Over 1970-1996. Part II: Sensitivity to the Eastward Penetration of the Equatorial Westerlies and to the Off-Equatorial O
Introducing new parameterizations of subsurface temperature and atmospheric convection in the Cane and Zebiak's model allows to reproduce oscillations with a period close to 4 years, equatorial wind anomalies that are located close to the dateline and realistic amplitudes of SST, wind and thermocline anomalies in the equatorial Pacific both in warm and cold phases.

(abstract) Role of Long Equatorial Wave Reflection in the Low-Frequency Variability Observed During the TOPEX/POSEIDON Period: Data Analysis and Coupled Model Study
The analysis of TOPEX/POSEIDON sea level and ERS-1 zonal wind stress data gives evidence that first mode meridonal long Rossby waves fully reflected into Kelvin waves at the equatorial western Pacific boundary at different periods including the January-June 1994 period. The evolution of the conditions (zonal wind stress, sea surface temperature and sea level anomalies) in the central Pacific suggests that this reflection may have played a role in the reversal of cold to warm anomalies observed in the central Pacific in June-July 1994. To investigate the actual role of reflected Kelvin waves observed by TOPEX/POSEIDON, a simple ocean-atmosphere coupled model is designed. Starting from these initial conditions, several simulations are run for testing the role western bundary reflection evidenced in TOPEX/POSEIDON data. Coupled mechanisms are suggested to explain the low-frequency variability observed during this period.

Onset and Forecast of the 1994-1995 El Nino Event: Equatorial Rossby Wave Reflection Evidenced by TOPEX/POSEIDON
We found evidence in TOPEX/POSEIDON sea level data that equatorial first meridionsl mode Rossby waves reflected at the Pacific western boundary into Kelvin waves during the January-july 1994 period prior to the 1994-1995 El Nino event.
