Abstract: Droughts are one of the most devastating natural hazards faced by the United States today. Severe droughts of the twentieth century have had large impacts on economies, society, and the environment, especially in the Great ...

Abstract: he spatial domain of the Asian monsoon has been defined by the intensity, seasonal concentration, and annual range of precipitation. Monsoon subdomains, such as the Indian monsoon, East Asian monsoon, and western North ...

Abstract: Higher temperatures increase the moisture-holding capacity of the atmosphere and can lead to greater atmospheric demand for evapotranspiration, especially during warmer seasons of the year. Increases in precipitation or ...

Abstract: AbstractDrought has severe consequences for humans and their environment, yet we have a limited understanding of the drivers of drought across the full range of time scales on which it occurs. Here, the atmosphere and ocean ...

Abstract: rojected changes in global rainfall patterns will likely alter water supplies and ecosystems in semiarid regions during the coming century. Instrumental and paleoclimate data indicate that natural hydroclimate fluctuations ...

Abstract: AbstractAccurate assessments of future climate impacts require realistic simulation of interannual?century-scale temperature and precipitation variability. Here, well-constrained paleoclimate data and the latest generation ...

Abstract: The recent availability of global networks of annual or seasonal resolution proxy data, combined with the few long instrumental and historical climate records available during the past few centuries, make it possible now ...

Abstract: AbstractMultidecadal hydroclimate variability has been expressed as ?megadroughts? (dry periods more severe and prolonged than observed over the twentieth century) and corresponding ?megapluvial? wet periods in many regions ...

Abstract: he distribution of climatic variance across the frequency spectrum has substantial importance for anticipating how climate will evolve in the future. Here power spectra and power laws (?) are estimated from instrumental, ...
