Joseph Clark

I am a postdoctoral research associate in the seasonal to decadal predictability division at GFDL studying seasonal predictability of atmospheric rivers and precipitation under the supervision of Nathaniel Johnson. Before my present position I was in the physics division, where I studied the sensitivity of Intertropical Convergence Zone to various configurational choices in idealized aquaplanet simulations under the supervision of Pu Lin. I received my PhD from The Pennsylvania State University in 2021. My research interests broadly revolve around atmospheric dynamics and climate variability, with particular attention to the processes driving climate change, extreme weather, teleconnections and subseasonal to seasonal climate predictability.
