Possible Association Between Recent Climate Extremes And The 2022 Hunga Tonga-
Hunga Ha'apai Eruption

Abstract
An unusually large increase in global mean temperature developed in 2023 for
reasons not yet fully understood. The most immediate culprit is A MAJOR EL
NINO that formed against the backdrop of global warming.
Other factors may include sharp declines in ship aerosol emissions over the
North Pacific this past decade, and perhaps also AN UNEXPECTED CLIMATE-SYSTEM
RESPONSE TO THE JANUARY 2022 ERUPTION OF HUNGA TONGA-HUNGA HA'APAI (TONGA), a
submarine volcano that INJECTED AN UNPRECEDENTED AMOUNT OF WATER VAPOR INTO
THE STRATOSPHERE.
Current literature suggests only small direct radiative effects, but dynamic
consequences of the eruption are poorly known. Here, we utilize reanalysis to
examine weather and climate extremes since the eruption, and find that
unusually large standardized anomalies (+/- 4 to 6 sigma from 20-year
climatology) may provide a Tonga "fingerprint".
Among the extreme events of interest are the record MARCH 2022 ANTARCTIC HEAT
WAVE AND THE 2022-2023 LA NINA. We hypothesize that the increased water vapor
from the eruption and subsequent cooling of the lower stratosphere intensified
the westerlies over the pacific and strengthened the Walker circulation.
The intensification of the Walker circulation resulted in the third
consecutive La Nina, which in turn amplified the El Nino that emerged in 2023.
Further research includes sensitivity tests to determine whether the third La
Nina would have occurred without the injection of water vapor from the
Eruption.
