Dr. Anthony Lupo has been examining the issue of drought in the Midwestern United States since 2000.  Work that has been published in several papers from his research group has shown that during certain years, precipitation occurs regularly throughout the spring and summer months, while during other years, there is a noticeable change in the frequency of precipitation that coincides with a change in the large-scale flow patterns.  These changes are also associated with changes in sea surface temperature patterns in the Eastern Pacific region, or changes in the phase of El Nino and Southern Oscillation (ENSO).  Later work has shown that the character of ENSO itself has been modulated by cycles that occur on even longer time scales.

Dr. Anthony R. Lupo is an Associate Professor of Atmospheric Science in the Department of Soil, Environmental, and Atmospheric Science at the University of Missouri – Columbia in Columbia, Missouri. He was a Fulbright Scholar to the Russian Academy of Sciences during the 2003-2004 academic year.
