An ENSO Survey: Precursors, Present Conditions,
and Potential Impacts
Dr. Michael Alexander, NOAA/ESRL
The El Niño Southern Oscillation (ENSO) is a key component of the
climate system that fluctuates on time scales of 2-7 years. During El
Niño events anomalously warm water extends across much of the
tropical Pacific Ocean in conjunction with an eastward shift of
precipitation, a weakening of the trade winds and a deeper
thermocline. The opposite conditions occur during La Niña events.
The Southern Oscillation, indicative of the difference in sea level
pressure between the tropical eastern and western Pacific/Australia,
is negative during EN episodes, with lower pressure over the east
Pacific. After a brief review of the components and theories of ENSO,
we will examine the current state of the tropical Pacific and how it
might evolve over the next few months. We will then explore some
current research issues including ENSO precursors, ENSO diversity if there are two (or more) types of events –and the potential impacts
of ENSO beyond the tropical Pacific.
Dr. Michael Alexander is a research meteorologist at the Physical Sciences
Division of the NOAA Earth System Research Laboratory in Boulder, Colorado.
He was a Lead Author of the Oceans Chapter in the 2014 National Climate
Assessment Report on Climate Change Impacts in the United States. Dr.
Alexander currently has three main research foci: air-sea-ice interactions,
processes that influence moisture transport and heavy precipitation the western
United States, and climate change impacts on marine ecosystems. His studies
of air-sea interaction include the influence of El Niño on global climate,
precursors to El Niño events, and the effects of midlatitude sea surface
temperatures and sea ice conditions on the atmospheric circulation. He recently
investigated how moisture moves through the gaps in the Sierra Nevada and
Cascade Mountains, resulting in heavy precipitation events in the US
intermountain west. He has also worked closely with marine biologists to study
how climate change may impact fish, such as the Atlantic croaker and river
herring.
