Internal Variability Role on Estimating Sea Level Acceleration in Fremantle Tide Gauge Station [PDF]

open access: yes, 2021
Low frequency internal signals bring challenges to signify the role of anthropogenic factors in sea level rise and to attain a certain accuracy in trend and acceleration estimations. Due to both spatially and temporally poor coverage of the relevant data

Impacts of Low-Frequency Internal Climate Variability and Greenhouse Warming on El Nino–Southern Oscillation

open access: yes, 2021
El Nino–Southern Oscillation (ENSO) is the dominant mode of interannual climate fluctuations with wide- ranging socioeconomic and environmental impacts. Understanding the eastern Pacific (EP) and central Pacific (CP) El Nino response to a warmer climate ...

Influence of internal climate variability on Indian Ocean Dipole properties [PDF]

open access: yes, 2018
The Indian Ocean Dipole (IOD) is the dominant mode of interannual variability over the tropical Indian Ocean (IO) and its future changes are projected to impact the climate and weather of Australia, East Africa, and Indonesia.

ASIRAS airborne radar resolves internal annual layers in the dry-snow zone of Greenland [PDF]

open access: yes, 2006
We present data from the European Space Agency's Airborne SAR/Interferometric Radar Altimeter System (ASIRAS), flown during the CryoVex 2004 field calibration/validation campaign, and new, high-resolution depth profiles of snow density measured in the ...

Decreasing surface chlorophyll in the tropical ocean as an indicator of anthropogenic greenhouse effect during 1998–2020

open access: yesEnvironmental Research Letters, 2023
Available satellite data reveal a decreasing trend in surface chlorophyll (SChl) over the entire tropical ocean until 2020. Where contributions by internal variability and external forcing remain unclear.

Simulated contribution of the interdecadal Pacific oscillation to the west Eurasia cooling in 1998–2013

open access: yesEnvironmental Research Letters, 2022
Large ensemble simulations with six atmospheric general circulation models involved are utilized to verify the interdecadal Pacific oscillation (IPO) impacts on the trend of Eurasian winter surface air temperatures (SAT) during 1998–2013, a period ...

How extreme could the near term evolution of the Indian Summer Monsoon rainfall be?

open access: yesEnvironmental Research Letters, 2022
We provide a methodology to estimate possible extreme changes in seasonal rainfall for the coming decades. We demonstrate this methodology using Indian summer monsoon rainfall as an example.

The Influences of Tropical Volcanic Eruptions with Different Magnitudes on Persistent Droughts over Eastern China

open access: yesAtmosphere, 2020
In this study, the influences on persistent droughts over Eastern China from tropical volcanic eruptions with three categories of magnitudes, i.e., 25 Tg, 50 Tg, and 100 Tg, were investigated through three groups of volcanic sensitivity experiments based

The role of external forcing and internal variability in regulating global mean surface temperatures on decadal timescales

open access: yesEnvironmental Research Letters, 2017
Global mean surface temperature (GMST) shows considerable decadal variations superimposed on a pronounced warming trend, with rapid warming during 1920–1945 and 1977–2000 and warming hiatuses during 1946–1976 and 2001–2013.
