TL;DR: In this article, a new climatic drought index, the standardized precipitation evapotranspiration index (SPEI), is proposed, which combines multiscalar character with the capacity to include the effects of temperature variability on drought assessment.

TL;DR: It is found that arid biomes respond to drought at short time-scales; that is, there is a rapid vegetation reaction as soon as water deficits below normal conditions occur, and that the response of vegetation to drought depends on characteristic drought time- scales for each biome.

TL;DR: In this paper, the authors forecast an increase in temperature and a decrease in precipitation at the end of the 21st century, which will enhance stress on natural forests and shrubs, and will result in more water consumption, evapotranspiration, and probably interception.

TL;DR: In this article, the performance of different drought indices for monitoring drought impacts on several hydrological, agricultural, and ecological response variables was evaluated. And the authors found that the SPEI was the index that best captured the responses of the assessed variables to drought in summer, the seas...

TL;DR: A monthly global dataset of a multiscalar drought index based on the standardized precipitation evapotranspiration index (SPEI) is presented and compared in terms of spatial and temporal variability with the existing continental and global drought datasets.
