South Atlantic tropical cyclones are unusual weather events that occur in the Southern Hemisphere. Strong wind shear , which disrupts the formation of cyclones , as well as a lack of weather disturbances favorable for development in the South Atlantic Ocean , make any strong tropical system extremely rare, and Hurricane Catarina in 2004 is the ...
Cyclones in the Southern Ocean tend to have lowest pressures in mid-late September, when Antarctic sea ice is at is maximum. The lower pressures are likely caused by less friction against sea ice rather than ocean waves. [1] As there are limited weather stations in the region, pressures in the region are calculated using results from ECMWF ...
Despite a midsummer lull over the Atlantic basin, AccuWeather meteorologists are monitoring a couple of tropical disturbances that could develop in the coming days. Either system could strengthen ...
The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS ) to higher-than-usual levels of ionizing ...
Off the charts “crazy” heat in the North Atlantic ocean and record-smashing Antarctic sea ice lows last year are far more severe than what Earth’s supposed to get with current warming levels.
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
On Bird Island, off the north-west tip of South Georgia in the Southern Atlantic Ocean, the team of six zoological field assistants at the research centre will be out to monitor the eggs of ...
An expedition in May 2008 by 19 scientists [18] studied the geology and biology of eight Macquarie Ridge sea mounts, as well as the Antarctic Circumpolar Current to investigate the effects of climate change of the Southern Ocean. The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times ...
