Tropical Water Vapor and Cloud Feedbacks in Climate Models : A Further Assessment Using Coupled Simulations

  title={Tropical Water Vapor and Cloud Feedbacks in Climate Models : A Further Assessment Using Coupled Simulations},
  author={D. Sun and Yongqiang Yu and Tao Zhang},
By comparing the response of clouds and water vapor to ENSO forcing in nature with that in Atmospheric Model Intercomparison Project (AMIP) simulations by some leading climate models, an earlier evaluation of tropical cloud and water vapor feedbacks has revealed the following two common biases in the models: 1) an underestimate of the strength of the negative cloud albedo feedback and 2) an overestimate of the positive feedback from the greenhouse effect of water vapor. Extending the same… CONTINUE READING
