A pathway for northern hemisphere extratropical cooling to elicit a tropical response

MT Luongo, SP Xie, I Eisenman… - Geophysical …, 2023 - Wiley Online Library
Previous studies have found that Northern Hemisphere aerosol‐like cooling induces a La

SM Larson, Y Okumura, K Bellomo… - Journal of …, 2022 - journals.ametsoc.org
Identifying the origins of wintertime climate variations in the Northern Hemisphere requires
careful attribution of the role of El Niño–Southern Oscillation (ENSO). For example, Aleutian …

The South Pacific meridional mode as a thermally driven source of ENSO amplitude modulation and uncertainty

SM Larson, KV Pegion, BP Kirtman - Journal of Climate, 2018 - journals.ametsoc.org
This study seeks to identify thermally driven sources of ENSO amplitude and uncertainty, as
they are relatively unexplored compared to wind-driven sources. Pacific meridional modes …
