Implication

Randomized trials demonstrate limited predictability of tropical intraseasonal variability, suggesting complex interactions with sea surface temperatures.

Key Points

This study examines how interannual sea surface temperature variability affects tropical intraseasonal variability predictability.
10-year simulation forced by climatological sea surface temperatures.
Analysis of a 10-member ensemble of simulations using observed sea surface temperatures from 1979-1988.
Induced predictability measures of tropical intraseasonal variability constructed from EOFs of precipitation and zonal wind.
Natural variability of tropical intraseasonal variability is substantial, with internal variability estimated at 50% of the mean signal.
Interannual TISV predictability is low on average, but exceptions exist during specific winters (e.g., 1982/83, 1997/98).
Simulations indicate some predictable characteristics of intraseasonal variance linked to ENSO-related sea surface temperature anomalies.
