Super Drought under Global Warming: Concept, Monitoring Index, and Validation

Drought under global warming: a review

This article reviews recent literature on drought of the last millennium, followed by an update on global aridity changes from 1950 to 2008. Projected future aridity is presented based on recent studies and our analysis of model simulations. Dry periods lasting for years to decades have occurred many times during the last millennium over, for example, North America, West Africa, and East Asia. ...

Increasing drought under global warming in observations and models

Historical records of precipitation, streamflow and drought indices all show increased aridity since 1950 over many land areas1,2. Analyses of model-simulated soil moisture3,4, drought indices1,5,6 and precipitation-minus-evaporation7 suggest increased risk of drought in the twenty-first century. There are, however, large differences in the observed and modelsimulated drying patterns1,2,6. Reco...

A Global Grassland Drought Index (GDI) Product: Algorithm and Validation

Existing drought indices have been widely used to monitor meteorological drought and agricultural drought; however, few of them are focus on drought monitoring for grassland regions. This study presented a new drought index, the Grassland Drought Index (GDI), for monitoring drought conditions in global grassland regions. These regions are vital for the environment and human society but suscepti...

Global warming and changes in drought

17 How is drought changing as the climate changes? Several recent papers in the scientific literature have focused on this question but the answer remains unclear. Here we attempt to understand this socially and ecologically relevant topic. We discuss what the expectations for changes in drought should be, and thus the prospects for the future, and we provide some recommendations for resolving ...
