The pacific is now being asked to file its own enso forecast

Yethikrishna ROriginal on Threads

the pacific is now being asked to file its own enso forecast: a geospatial transformer reaches skillful predictions sixteen months out from spring by coupling the tropical basins, a glass box dynamical deep learning model extends that to nineteen months and hindcasts the 2015 super el nino, and a cmip6 trained cnn finds historical forcing lifts enso predictability by 14 percent.

the ocean now files its own phase.

Context

The geospatial transformer is GL-Geoformer, from Science Advances, Tropical basin interactions reduce spring predictability barrier of ENSO in a deep learning model. The abstract says incorporating tropical basin interactions substantially reduces the spring predictability barrier, giving skillful ENSO predictions up to 16 months ahead when initiated in spring, with pacemaker experiments on the Indian Ocean Dipole and Atlantic Nino.

The glass-box model is in npj Climate and Atmospheric Science (2026), built with dynamical system deep learning, a transparent multivariate ENSO model with skillful predictions up to 19 months ahead that hindcasts the onset, intensity and decay of the 2015-2016 super El Nino more than a year in advance. The CNN study is in Science Advances: with a leave-one-out strategy on CMIP6 historical and preindustrial control runs, ENSO predictability is enhanced by 14.0 plus or minus 1.8% under historical anthropogenic forcing.

How it compares

All three numbers match their abstracts. They are three separate studies on different data and different skill definitions, so 16 and 19 months are not a like-for-like ranking of the two models. The 14 percent is a change in predictability measured in climate model simulations, not a gain in forecast skill for real events. The note's phrase 'more than a year' for the 2015 hindcast comes from the abstract excerpt, and the excerpt read is cut off at that point.

Watch next
