A recent study bridges observations and modeling, and shows a way to make improvements to the observational instruments climate scientists rely on to study global circulation patterns. 

Study Proposes New Way to Define Drought, Capturing Natural Variations and Human Actions 18 May 2021

Study Proposes New Way to Define Drought, Capturing Natural Variations and Human Actions

While drought is commonly defined by precipitation and runoff deficits, the study challenges this understanding by proposing a new definition: anthropogenic drought. Within human‐water systems, drought must be defined and understood as the complex and interrelated dynamics of both natural and human‐induced changes, the authors say.
