NAO: Driving Climate Across the Atlantic

Abstract:: This interactive feature story is part of Science Bulletins, an innovative online and exhibition program that offers the public a window into the excitement of scientific discovery. Published in September 2004, this EarthBulletin examines what scientists have recently learned about the North Atlantic Oscillation climate pattern. It includes the following components: Four online essays -- NAO Who?, How NAO Does Its Thing, NAO Data Hunting (and Gathering), Forecasting the Unpredictable -- each available in a print-friendly format; A seven-minute feature video, NAO: Driving Climate Across the North Atlantic, available in two download speeds; A full-color map showing oscillating pressure systems in the North Atlantic; An interactive that looks at the positive and negative phases of NAO; An interactive that examines how NAO may have affected recent history;A pop-up glossary of the terms used in this Earth Bulletin.

Paleoceanography, Spring 2004

Abstract:: This class examines tools, data, and ideas related to past climate changes as seen in marine, ice core, and continental records. The most recent climate changes (mainly the past 500,000 years, ranging up to about 2 million years ago) will be emphasized. Quantitative tools for the examination of paleoceanographic data will be introduced (statistics, factor analysis, time series analysis, simple climatology).

No Strings Attached

Abstract:: The El Nino-La Nina event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. A strong upwelling of unusually warm water was observed in the Pacific Ocean during the El Nino phase, followed by unusually cold water in the La Nina phase. The Advanced Very High Resolution Radiometer (AVHRR) instrument on the US National Oceanic and Atmospheric Administrations NOAA-14 spacecraft observed the changes in sea surface temperature shown here.
