Atlantic Basin – Weather and Climate Discussion

Have aerosols caused the observed North Atlantic multidecadal variability?

March 1, 2013 Jon Robson

By Jon Robson Multidecadal changes in the North Atlantic sea surface temperature (NASST) have been linked to a range of important climate impacts in Europe, Africa (most notably Sahel rainfall) and North and South America. Indeed, in the mid 1990s an increase in hurricane numbers, and a shift in European climate (notably to wet and … Continue reading “Have aerosols caused the observed North Atlantic multidecadal variability?”

A case study of Multidecadal climate variability and prediction: The mid 1990s warming of the North Atlantic

March 9, 2012 Jon Robson

The Earth is a complex system of interacting components, such as the atmosphere and ocean, which produce a wide variety of natural variability. This natural variability ensures that the evolution of a particular region’s climate, e.g. that of Western Europe, could be completely different to another region, or indeed the global mean climate. Such variability … Continue reading “A case study of Multidecadal climate variability and prediction: The mid 1990s warming of the North Atlantic”

Atlantic Hurricane Season About to Get Busy

August 12, 2010 ricardo

The North Atlantic has been very quiet since Hurricane Alex in late June. Alex was the strongest storm in terms of wind speed in the month of June since Alma (1966). However, and according to NOAA’s 2010 Updated Atlantic Hurricane Season Outlook issued on 5th August, the Atlantic Basin remains on track for an active … Continue reading “Atlantic Hurricane Season About to Get Busy”

Atlantic Tropical Basin Heating Up

August 2, 2010 ricardo

After a relatively quiet start, the tropics are beginning to show some signs of life in the far-eastern Atlantic. An elongated cluster of showers and thunderstorms over the southeastern Atlantic is slowly organizing as it moves generally west to west-northwest. Dry air remains to the north as the system is experiencing little in the way … Continue reading “Atlantic Tropical Basin Heating Up”
