Nonlinearity in the North Pacific Atmospheric Response to a Linear ENSO Forcing

Geophysical Research Letters, 2019
El Niño Southern Oscillation (ENSO) exerts a remote impact on the North Pacific and North American winter climate. Both observational and model studies have suggested nonlinearities in this teleconnection.

Empirical Orthogonal Teleconnections

Journal of Climate, 2000
Abstract A new variant is proposed for calculating functions empirically and orthogonally from a given space–time dataset. The method is rooted in multiple linear regression and yields solutions that are orthogonal in one direction, either space or time. In normal setup, one searches for that point in space, the base point (predictor), which, by linear

Stratospheric Ozone Depletion Causes Southern Ocean Surface Cooling

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Stratospheric ozone depletion strongly influences Southern Ocean climate change. Using coupled climate model simulations, we quantify the transient effect of stratospheric ozone depletion on sea surface temperature (SST) over the Southern Ocean from 1982 to 2005.

An Atmosphere–Land–Ocean Coupled Global NWP System: Performance Evaluation for Potential Operational Use

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract This study assesses the influence of ocean–atmosphere coupling on short‐ and medium‐range forecasts of the July 2024 Indian summer monsoon using the newly configured coupled NCMRWF Unified Model (C‐NCUM). Forecasts are evaluated against the operational atmosphere–land model (NCUM) using GPM rainfall, OSTIA SSTs, and reanalysis‐derived moisture

Track‐Dependent Links Between Tropical Cyclones and Extratropical Predictability in Physical and AI Models

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global medium‐range weather forecasts suffer occasional failures (“busts”) linked to tropical cyclones (TCs). We investigate TC influences on extratropical predictability by comparing forecasts from a physics‐based model (ECMWF‐IFS) and an AI‐hybrid model (Google‐NGCM) initialized near TC genesis.

An interdecadal shift of the extratropical teleconnection from the tropical Pacific during boreal summer

, 2019
The extratropical teleconnection from the tropical Pacific in boreal summer exhibits a significant shift over the past 70 years. Cyclonic circulation anomalies over the North Atlantic and Eurasia associated with El Niño in the later period (1978‐2014 ...

Impacts of large-scale teleconnection indices on chill accumulation for specialty crops in California

, 2021
Although the impacts of teleconnection indices on climate metrics such as precipitation and temperature in California have been widely studied, less attention has been given to the impact on integrated climate indices such as chill accumulation.

Wavelet Analysis of Hydroclimatic Teleconnections and Precipitation Variability Over Ethiopia

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article investigates the variability of precipitation across Ethiopia by analyzing monthly and annual rainfall data from five stations representing the north, east, west, south, and central regions over a 31-year period (1987–2017).

Climate Change Alters Teleconnections

Geophysical Research Letters
Abstract Internal modes of climate variability, such as El Niño and the North Atlantic Oscillation (NAO), can have strong influences upon distant weather patterns, effects that are referred to as “teleconnections.” The extent to which anthropogenic climate change has and will continue to affect these teleconnections, however, remains ...
