Soil Moisture Conditions Determine Land?Atmosphere Coupling and Drought Risk in the Northeastern United States
نویسندگان
چکیده
Strengthened land-atmosphere coupling in the northeastern United States (NEUS), accompanied by a positive soil moisture-rainfall feedback, may lead to more drought. Coupling between land and atmosphere emerges when low moisture values limit surface latent heat flux, or evapotranspiration, so that majority of absorbed solar radiation is emitted from as sensible heat. In this study, Weather Research Forecasting model was run with four prescribed levels across 7 years elucidate strength under potential, future states NEUS. Under drier conditions, strengthens, moisture-precipitation feedback develops all despite differences amount advected into study domain. As snowpack decreases evaporative demand increases, conditions become summers over NEUS, resulting frequent development

A baseline probabilistic drought forecasting framework using standardized soil moisture index: application to the 2012 United States drought
The 2012 drought was one of the most extensive drought events in half a century, resulting in over USD 12 billion in economic loss in the United States and substantial indirect impacts on global food security and commodity prices. An important feature of the 2012 drought was rapid development and intensification in late spring/early summer, a critical time for crop development and investment pl...
متن کاملThe role of soil ice in land‐atmosphere coupling over the United States: A soil moisture–precipitation winter feedback mechanism
[1] We perform two 23 year simulations using a regional climate model coupled with the National Center for Atmospheric Research Community Land Model version 3.5 (RegCM‐CLM) to investigate land‐atmosphere coupling in the continental United States during the cold season (October–April) and the role of soil water phase. One simulation allows the land surface to interact freely (RunI) while the oth...

In 2010, the United States adopted its first-ever comprehensive set of health system reforms in the Affordable Care Act (ACA). Implementation of the law, though politically contentious and controversial, has now reached a stage where reversal of most elements of the law is no longer feasible. The controversial portions of the law that expand affordable health insurance coverage to most U.S. cit...
متن کاملNature and Possible Causes of the Northeastern United States Drought during 196265
During the past 4 years noteworthy weather fluctuations of a persistent kind have occurred over large portions of the United States, the most prominent of which have been the deficiency in precipitation over the Northeast and the excess over the Southwest and the Northern Plains. The nature of these abnormalities is described with the help of seasonal frequency distributions of precipitation de...
متن کاملRace, Education Attainment, and Happiness in the United States
Background and aims: As suggests by the Minorities’ Diminished Returns (MDR) theory, educationattainment and other socioeconomic status (SES) indicators have a smaller impact on the health andwell-being of non-White than White Americans. To test whether MDR also applies to happiness, in thepresent study, Blacks and Whites were compared in terms of the effect of education attai...
