South Asian summer monsoon projections constrained by the Intedacadal Pacific Oscillation

, 2020
A reliable projection of future South Asian summer monsoon (SASM) benefits a large population in Asia. Using a 100-member ensemble of simulations by the Max Planck Institute Earth System Model (MPI-ESM) and a 50-member ensemble of simulations by the ...

Tropical Oceanic Causes of Interannual to Multidecadal Precipitation Variability in Southeast South America over the Past Century [PDF]

, 2010
Observations, atmosphere models forced by historical SSTs, and idealized simulations are used to determine the causes and mechanisms of interannual to multidecadal precipitation anomalies over southeast South America (SESA) since 1901.

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

International Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Multidecadal trends in the nesting phenology of Pacific and Atlantic leatherback turtles are associated with population demography

Endangered Species Research, 2014
Knowledge of the mechanisms influencing phenology can provide insights into the adaptability of species to climate change. Here, we investigated the factors influencing multidecadal trends in the nesting phenology of the leatherback turtle Dermochelys ...

Evidences for a quasi 60-year North Atlantic Oscillation since 1700 and its meaning for global climate change

, 2012
The North Atlantic Oscillation (NAO) obtained using instrumental and documentary proxy predictors from Eurasia is found to be characterized by a quasi 60-year dominant oscillation since 1650.

ENSO suppression due to weakening of the North Atlantic thermohaline circulation [PDF]

, 2005
Changes of the North Atlantic thermohaline circulation (THC) excite wave patterns that readjust the thermocline globally. This paper examines the impact of a freshwater-induced THC shutdown on the depth of the Pacific thermocline and its subsequent ...

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

A Hemispheric Mechanism for the Atlantic Multidecadal Oscillation

Journal of Climate, 2007
Abstract The physical processes associated with the ∼70-yr period climate mode, known as the Atlantic multidecadal oscillation (AMO), are examined. Based on analyses of observational data, a deterministic mechanism relying on atmosphere–ocean–sea ice interactions is proposed for the AMO.

Using a causal effect network approach to quantify the impact of ENSO teleconnections on summer monsoon precipitation over the Himalayas and key regional circulations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We quantified the causal effect (CE) of linkages between four monthly climate indices ENSO, SMHP, RWC, and MHC for 1940–2022 with a time lag of one month. The results show CE values from (1) ENSO to SMHP of −0.33$$ -0.33 $$ to −0.44$$ -0.44 $$ (i.e., a one standard deviation (SD) increase in ENSO causes a decrease in SMHP of −0.33$$ -0.33 $$ to −0.44$$

Spurious Indo‐Pacific Connections to Internal Atlantic Multidecadal Variability Introduced by the Global Temperature Residual Method

Geophysical Research Letters, 2023
The relative contributions of external forcing and internal processes to the observed spatial and temporal characteristics of “Atlantic Multidecadal Variability” (AMV) are still under debate.
