Climate Dynamics

Understanding the mechanisms responsible for climate variability and change is a major research theme in CCR. Our center has been at the forefront of unraveling the causes of past, present, and future variations in climate, using an array of modeling and statistical tools. Researching regional climate change across the world, CCR scientists are currently studying the drivers and predictability of monsoon circulations, El Niño-Southern Oscillation, African vegetation dynamics, Middle Eastern dust storms, Great Lakes warming trends, and Arctic climate change.
