Will the sensitivity of the atmosphere to the primary mechanism at the heart of El Niño — that is, feedback between the higher sea temperatures and slowing trade winds, leading to atmospheric convection over the central Pacific — continue in the future?

Not exact matches

The researchers have also identified smaller circulations that could significantly affect atmospheric chemistry such as the North American monsoon and convections over Africa.

«For various periods over the last 60 years, we have been able to combine important processes: atmospheric variability, such as the North Atlantic Oscillation, water and air temperatures, the occurrence of fresh surface water, and the duration of convection,» explains Dr. Marilena Oltmanns from GEOMAR, lead author of the study.

These convection changes can in turn drive the formation of an atmospheric ridge in the North Pacific, resulting in significant drying over California.

http://www.cpc.ncep.noaa.gov/products/outreach/glossary.shtml Low atmospheric pressure tends to occur over warm water (and high over cold water), partly because of deep convection over the warm water.

As the central part of the Pacific warms up during El Niño, the atmospheric convection that normally occurs over the western warm pool migrates to the central Pacific.
