Central Great Plains precipitation deficits during May–August 2012 were the most severe since at least 1895, eclipsing the Dust Bowl summers of 1934 and 1936. Drought developed suddenly in May, following near-normal precipitation during winter and early spring. Its proximate causes were a reduction in atmospheric moisture transport into the Great Plains from the Gulf of Mexico. Processes that generally provide air mass lift and condensation were mostly absent, including a lack of frontal…

The Physics of Drought in the U.S. Central Great Plains

AbstractThe semiarid U.S. Great Plains is prone to severe droughts having major consequences for agricultural production, livestock health, and river navigation. The recent 2012 event was accompanied…

The worst North American drought year of the last millennium: 1934

During the summer of 1934, over 70% of western North America experienced extreme drought, placing this summer far outside the normal range of drought variability and making 1934 the single worst…

Separate tree-ring reconstructions of spring and summer moisture in the northern and southern Great Plains

The two most severe droughts to impact the Great Plains in the twentieth century, the 1930s Dust Bowl and 1950s Drought, were the result of multiyear moisture deficits during the spring and…

Drier spring over the US Southwest as an important precursor of summer droughts over the US Great Plains

Abstract. This study addresses the role of atmospheric moisture budget in determining the onset and development of the summer droughts over the North American Great Plains (GP) using two…

Dynamical Causes of the 2010/11 Texas–Northern Mexico Drought*

AbstractThe causes of the Texas–northern Mexico drought during 2010–11 are shown, using observations, reanalyses, and model simulations, to arise from a combination of ocean forcing and internal…

Atmosphere and Ocean Origins of North American Droughts

AbstractThe atmospheric and oceanic causes of North American droughts are examined using observations and ensemble climate simulations. The models indicate that oceanic forcing of annual mean…

Potential predictability sources of the 2012 U.S. drought in observations and a regional model ensemble

The 2012 drought was the most severe and extensive summertime U.S. drought in half a century with substantial economic loss and impacts on food security and commodity prices. A unique aspect of the…

Projection of American dustiness in the late 21st century due to climate change

It is projected that climate change will increase dust activity in the southern Great Plains from spring to fall in the late half of the twenty-first century – largely due to reduced precipitation, enhanced land surface bareness, and increased surface wind speed.

An intensified seasonal transition in the Central U.S. that enhances summer drought

In the long term, precipitation in the Central U.S. decreases by 25% during the seasonal transition from June to July. This precipitation decrease has intensified since 1979 and such intensification…

Distinct causes for two principal U.S. droughts of the 20th century

Diagnosis of observational and climate model data reveals that the two major U.S. droughts of the 20th Century had distinct causes. Drought severity over the Southern Plains during 1946–1956 is very…

Modeling of Tropical Forcing of Persistent Droughts and Pluvials over Western North America: 1856–2000*

Abstract The causes of persistent droughts and wet periods, or pluvials, over western North America are examined in model simulations of the period from 1856 to 2000. The simulations used either (i)…

Through an analysis of 15 coupled climate models it is shown here that the drying in southwest North America is driven by a reduction of winter season precipitation associated with increased moisture divergence by the mean flow and reduced moisture convergence by transient eddies.

Amplification of the North American “Dust Bowl” drought through human-induced land degradation

It is shown that the inclusion of forcing from human land degradation during the period, in addition to the anomalously SSTs, is necessary to reproduce the anomalous features of the Dust Bowl drought and is improved when the new dust aerosol and vegetation boundary conditions are included.

Causes of long-term drought in the U

The United States Great Plains (USGP) experienced a number of multi-year droughts during the last century, most notably the droughts of the 1930s and 1950s. This study examines the causes of such…

Prospects for Dynamical Prediction of Meteorological Drought

AbstractThe prospects for U.S. seasonal drought prediction are assessed by diagnosing simulation and hindcast skill of drought indicators during 1982–2008. The 6-month standardized precipitation…

Pacific and Atlantic Ocean influences on multidecadal drought frequency in the United States

Should the current positive AMO (warm North Atlantic) conditions persist into the upcoming decade, it is suggested two possible drought scenarios that resemble the continental-scale patterns of the 1930s and 1950s drought.
