Winter 2013 What if the drought continues for another year(s)? David W. Freeman OSU Extension Equine Specialist The following pictures show the magnitude and progression of drought in the U.S. over the past three years (December 2010 to 2012 from The National Weather Services Climate Prediction Center website). We love orange at Oklahoma State University; however, in this case, we just as soon not see so much. The yellow to orange colored regions show locations of severe to extreme drought. Much of the central re-gion of the U.S. has expanded into large scale severe to extreme drought over the past three years. There is historical precedent of multi-year drought in Oklahoma. Much has been recorded about the 1930’s ‘dust bowl’ and the disas-trous consequences centered around the Oklahoma panhandle. A web -report from the Oklahoma Mesonet reminds us that multi-year epi-sodes of drought continue to occur: “Drought episodes can last from a few months to several years. Since modern climatological record-keeping began in the late nineteenth century, the state has seen five major multi-year and multi-regional drought events. These occurred in the late 1890s, from 1909-18, 1930-40, 1952-58 and, to a lesser extent, 1962-72. Each of these episodes contained at least one year of above-normal rainfall. The drought of the 1930s is associated with the Dust Bowl of the Great Plains, when socio-economic conditions, agricultural practices and drought forced the largest emigration of Oklahomans in state history.” (OKLAHOMA’S CLIMATE: AN OVERVIEW web report from Oklahoma mesonet ht t p : / / c l imat e .me s one t . o r g / count y _ c l i m a t e / P r oduc t s / oklahoma_climate_overview.pdf). The Oklahoma Climatological Survey compiles annual precipitation records. A graph of rainfall patterns over the past 100 years shows somewhat of a cyclic pattern to rainfall amounts. The graph, shown on the next page, documents the pattern of multiple years of above aver-age rainfall followed by multiple years of below rainfall since the be-ginning of the 20th century. Looking across the last 30 years, one might come to the conclusion that we have been ‘overdue’ for a drought episode for several years. Oklahoman’s have been blessed with above average rainfall amounts for most years since the early 1980’s, that is until the last couple of years. We’ve become accus-tomed to receiving these above average amounts to supply our surface water and fuel our forage production.
