Climate variablity in the southern hemisphere
Global Change magazine, Issue 76. IGBP, 2011Most studies that reconstruct the climatic conditions of the past
centuries to millennia tend to focus on the northern hemisphere.
But now an intriguing multicentennial record of temperature and
precipitation in southern South America is available. Raphael
Neukom and Jürg Luterbacher elaborate on its significance.

Has the Drake Passage Played an Essential Role in the Cenozoic Cooling?
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Zhang Zi-Yin; Gong Zhong-Shi; Yan Qing; et al. - Science Press, 2010The Drake Passage is the seaway between South America and Antarctica. It is widely believed that the thermal isolation effects caused by the opening of the Drake Passage played an important role in the abrupt cooling that occurred at the Eocene-Oligocene boundary in the Cenozoic. These effects are also thought to be independent of the geometry of the passage. Here, the authors demonstrate that the climate impacts of the Drake Passage depend on the passage geometry by comparing the climate’s sensitivity to the opening of the Drake Passage under the present and the Early Eocene land-sea configur ...

in Atmospheric and Oceanic Science Letters > Volume 3 Number 5 (16 September 2010) . - p.288-292The Drake Passage is the seaway between South America and Antarctica. It is widely believed that the thermal isolation effects caused by the opening of the Drake Passage played an important role in the abrupt cooling that occurred at the Eocene-Oligocene boundary in the Cenozoic. These effects are also thought to be independent of the geometry of the passage. Here, the authors demonstrate that the climate impacts of the Drake Passage depend on the passage geometry by comparing the climate’s sensitivity to the opening of the Drake Passage under the present and the Early Eocene land-sea configurations. These experiments show that the thermal isolation effects caused by the passage are much stronger under the present land-sea configuration. In comparison, under the Early Eocene land-sea configuration, the weak anomalies in heat transport caused by the opening of the narrow and shallow Drake Passage are not strong enough to thermally insulate Antarctica. The climate effects of the Drake Passage on the Cenozoic cooling have been overestimated in previous sensitivity studies carried out using the present land-sea configuration. Thus, it is unlikely that the opening of the Drake Passage played an essential role in the abrupt Cenozoic cooling, especially in the abrupt cooling at the Eocene-Oligocene boundary.

Journal of Climate
AMS, 1888-[...]Published semimonthly by the American Meteorological Society, the Journal of Climate covers climate research and, therefore, welcomes manuscripts concerned with large-scale variability of the atmosphere, oceans, and land surface, including the cryosphere; past, present, and projected future changes in the climate system (including those caused by human activities); and climate simulation and prediction. Occasionally the Journal of Climate will publish review articles on particularly topical areas. Such reviews must be approved by the Chief Editor prior to submission.
