Cécile Hannay

I am an associate scientist in the Atmospheric Modeling and Predictability Section within the Climate and Global Dynamics Division at NCAR. My research interests include clouds, their impact on climate and their representation in climate models. Clouds play a fundamental role in the global climate system through their impacts on the radiative budget. They modify the earth's radiation budget by altering the absorption, scattering and reflection characteristics of the atmosphere. The parameterization of clouds is one of the greatest sources of uncertainty in climate predictions. It is imperative to improve our representations of clouds in order to more accurately predict climate. I am the NCAR liaison for the Climate Process Team (CPT) on Low-Latitude Cloud Feedbacks on Climate Sensitivity. Our goal is to increase the understanding of tropical and subtropical cloud feedbacks on climate sensitivity and to reduce the large uncertainty in the climate model simulations of these feedbacks.
