Spatial extents of tropical droughts during El Niño in current and future climate in observations, reanalysis, and CMIP5 models

Many regions of the planet are extremely vulnerable to drought. In the tropics, the El Niño/Southern Oscillation (ENSO) phenomenon is recognized as a key driver of drought occurrence. In this study, we analyze the spatial extent of droughts over tropical land regions and evaluate its connection to ENSO in the recent past in observations and … Read More

Surprising News: Drylands Are Not Getting Drier

Professor Lintner recently co-authored a Nature Climate Change study on soil moisture-atmosphere feedbacks in drylands.  The findings of the study suggest that soil moisture exerts a negative feedback on surface water availability in drylands, offsetting some of the expected decline in water availability over these areas.
