Evolution of the Southern Annular Mode during the past millennium [PDF]

open access: yesNature Climate Change, 2014
The Southern Annular Mode (SAM) is the primary pattern of climate variability in the Southern Hemisphere1, 2, influencing latitudinal rainfall distribution and temperatures from the subtropics to Antarctica. The positive summer trend in the SAM over recent decades is widely attributed to stratospheric ozone depletion2; however, the brevity of ...

Aspects of intraseasonal variability of Antarctic sea ice in austral winter related to ENSO and SAM events

open access: yesJournal of Glaciology, 2017
We performed an Empirical Orthogonal Function (EOF) analysis to assess the intraseasonal variability of 5–60 day band-pass filtered Antarctic sea-ice concentration in austral winter using a 20-year daily dataset from 1995 to 2014.

Solar cycle modulation of the Southern Annular Mode

open access: yesGeophysical Research Letters, 2005
The effect of the 11‐year solar cycle modulation on the Southern Annular Mode (SAM) in the Southern Hemisphere is examined through analysis of observational data from 1968 to 2001. It is found that the year‐to‐year variability of the October–November mean SAM differs significantly according to the solar activity.

A simple analytical model to study and control azimuthal instabilities in annular combustion chambers [PDF]

open access: yes, 2012
This study describes a simple analytical method to compute the azimuthal modes appearing in annular combustion chambers and help analyzing experimental, acoustic and LES (Large Eddy Simulation) data obtained in these combustion chambers. It is based on

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

The response of the southern annular mode, the east Australian current, and the southern mid-latitude ocean circulation to global warming

open access: yes, 2005
Climate models predict an upward trend of the Southern Annular Mode (SAM) in response to increasing atmospheric CO2 concentration, however the consequential impact of this change on oceanic circulation has not been explored.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Mitigation of 21st century Antarctic sea ice loss by stratospheric ozone recovery

open access: yesGeophysical Research Letters, 2012
We investigate the effect of stratospheric ozone recovery on Antarctic sea ice in the next half‐century, by comparing two ensembles of integrations of the Whole Atmosphere Community Climate Model, from 2001 to 2065.

Revisiting Cloud Radiative Heating and the Southern Annular Mode

open access: yesGeophysical Research Letters, 2022
AbstractCloud‐circulation interactions have a potentially large but uncertain influence on regional climate. Here we use satellite observations to investigate relationships between atmospheric cloud radiative heating and hemispheric‐scale shifts in the Southern Hemisphere extratropical jet stream, as represented by the Southern Annular Mode.

Does the Southern Annular Mode contribute to the persistence of the multidecade-long drought over southwest Western Australia?

open access: yes, 2011
[1] Record low austral winter rainfall totals over southwest Western Australia (SWWA) in 2010 saw a continuation of the multidecade-long winter drought plaguing the region.
