Raising Central American Orography Improves Climate Simulation

Wednesday, Jun 9, 2021

A new paper, published recently and led by AOS Alum Jane Baldwin (Columbia University), with CIMES Director Gabe Vecchi, an AOS faculty member, among others, suggests that a significant portion of the double Inter-Tropical Convergence Zone (ITCZ)  bias originates from low biases in Central American orography in models. The study offers a simple and computationally inexpensive yet physically based method for improving pervasive double ITCZ bias. The research is based on the work Jane began while at Princeton and is published in AGU Advances and highlighted as an Eos Editor's Highlight.
