Phenological Changes in the Southern Hemisphere
Current evidence of phenological responses to recent climate change is substantially biased towards northern hemisphere temperate regions. Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other regions on the planet. We conduct the largest met...
متن کاملSustaining health in the southern hemisphere.
The human c-myc proto-oncogene is the genomic homologue of the transforming sequences found in MC29, an avian retrovirus that can cause myelocytomatosis, carcinoma, sarcoma and lymphoma (Graf & Beug, 1978; Enrietto et al., 1983). Alterations in the structure or expression of c-myc have been associated with several forms of neoplasia including avian leukosis virus induced B-cell lymphoma, rodent...
متن کاملStratosphere–Troposphere Coupling in the Southern Hemisphere
This study examines the temporal evolution of the tropospheric circulation following large-amplitude variations in the strength of the Southern Hemisphere (SH) stratospheric polar vortex in data from 1979 to 2001 and following the SH sudden stratospheric warming of 2002. In both cases, anomalies in the strength of the SH stratospheric polar vortex precede similarly signed anomalies in the tropo...
متن کاملDecadal variability in the Southern Hemisphere
[1] This study reveals that a quasi‐decadal variability exists in the climate system of southern high latitudes, particularly in the Southern Annular Mode (SAM) and subpolar to mid latitudes sea surface temperature (SST), based on in situ observations, reanalysis data, and the 20th Century runs of IPCC AR4 coupled climate models. Spectral analysis reveals that a statistically significant variab...
