ENSO Performance

Metric collection "El Niño - Southern Oscillation (ENSO) performance in historical simulations"

Description

This metric collection evaluates climate models for both the background climatology (time mean and seasonal cycle) and ENSO properties.

Common properties

Pre-processing of data:

• detrending: linear
• frequency: monthly
• minimum length of simulation: 100 years

Metrics list

Time-mean climate (RMSE):

• Meridional mean eastern Tropical Pacific precipitation (PR) (double_ITCZ_bias)
• Zonal mean equatorial Pacific precipitation (PR) (eq_PR_bias)
• Zonal mean equatorial Pacific sea surface temperature (SST) (eq_SST_bias)
• Zonal mean equatorial Pacific zonal wind stress (Taux) (eq_Taux_bias)

Seasonal cycle amplitude (RMSE):

• Meridional seasonal cycle's amplitude of precipitation (PR) in the eastern Tropical Pacific (double_ITCZ_sea_cycle)
• Zonal seasonal cycle's amplitude of precipitation (PR) in the equatorial Pacific (eq_PR_sea_cycle)
• Zonal seasonal cycle's amplitude of sea surface temperature (SST) in the equatorial Pacific (eq_SST_sea_cycle)
• Zonal seasonal cycle's amplitude of zonal wind stress (Taux) in the equatorial Pacific (eq_Taux_sea_cycle)

ENSO pattern (RMSE):

• Zonal SSTA during ENSO (ENSO_pattern)

ENSO lifecycle (RMSE):

• Temporal evolution of SSTA centered on ENSO (ENSO_lifecycle)

ENSO properties (absolute value of the relative difference):

• ENSO amplitude (ENSO_amplitude)
• ENSO seasonal timing (ENSO_seasonality)
• ENSO asymmetry (ENSO_asymmetry)
• ENSO duration (ENSO_duration)
• ENSO diversity (ENSO_diversity)
