Global Drought Information System - Drought Characterization, Occurrence, Driving Mechanisms, and Predictability Worldwide (GDIS Worldwide)
This special collection of the Journal of Climate is devoted to our understanding of drought throughout the world. The idea for this collection came about as a recommendation of a 2012 international workshop on the development of a Global Drought Information System (GDIS) sponsored by WCRP and various partner organizations (ESA-ESRIN, NASA, NIDIS, NSF, GEO, USCLIVAR, and NOAA). The collection is an important step in the development of a GDIS, providing a comprehensive overview of the state of our understanding of drought, as well as recent research advances. Individual papers solicited for this collection focus on specific large regions/continents that collectively encompass most of the world. Specific aspects of drought that are considered include its overall characterization and metrics, key physical mechanisms and drivers, impacts, trends, and predictability. A synthesis paper attempts to organize the many facets of drought throughout the world into a global view as well as to provide an overall assessment of high priority drought research challenges.
