Atmospheric circulation changes and neoglacial conditions in the Southern Hemisphere mid-latitudes: Insights from PMIP2 simulations at 6 kyr
(2011)
Glacial geologic studies in the Southern Hemisphere (SH) mid-latitudes (40-54°S) indicate renewed glacial activity in southern South America (Patagonia) and New Zealand's (NZ) South Island starting at ~7 kyr, the so-called ...
The northern and southern mid-latitude ionospheric trough using global IGS vTEC maps
(Elsevier, 2020-05)
The aim of this work is the analysis of the mid-latitude ionospheric trough (MIT) using the Global Ionospheric Maps from IGS (GIMs) during the solar minimum, year 2008. This study was performed for different local times, ...
Postmidnight mid-latitude ionospheric trough position oscillations during solar cycle 24
(Elsevier, 2021-08)
In this work, the Global Ionospheric Maps (GIMs) are used to analyze the behavior of the mid-latitude ionospheric trough (MIT) during the solar cycle 24 (2008–2019). This analysis is performed for the Northern and Southern ...
PCA and vTEC climatology at midnight over mid-latitude regions
(Springer, 2017-12)
The effect of the thermospheric vertical neutral wind on vertical total electron content (vTEC) variations including longitudinal anomaly, remaining winter anomaly, mid-latitude summer night anomaly, and semiannual anomaly ...
Fronts and precipitation in CMIP5 models for the austral winter of the Southern Hemisphere
(Springer, 2018-04)
Wintertime fronts climatology and the relationship between fronts and precipitation as depicted by a group of CMIP5 models are evaluated over the Southern Hemisphere (SH). The frontal activity is represented by an index ...
Changes in biomass burning mark the onset of an ENSO-influenced climate regime at 42 degrees S in southwest Tasmania, Australia
(Elsevier, 2015)
We use macroscopic charcoal and sediment geochemistry analysis of two proximal upper montane lakes located at 42 degrees S in southwest Tasmania, Australia, to test the role of the southern hemisphere westerly winds (SWW) ...
Interactive comment on “Modelled glacier equilibrium line altitudes during the mid-Holocene in the southern mid-latitudes”
(Copernicus Gesellschaft MBH, 2015)
Glacier behaviour during the mid-Holocene (MH, 6000 years BP) in the Southern Hemisphere provides observational data to constrain our understanding of the origin and propagation of palaeoclimate signals. In this study we ...
Poleward shift and change of frontal activity in the Southern Hemisphere over the last 40 years
(American Meteorological Society, 2014-01)
Several studies have documented the poleward shift of the midlatitude westerly jet of the Southern Hemisphere during the last decades of the twentieth century, mainly during the warm season. In this work the consistency ...
