Spatial Decomposition of Climate Feedbacks in the Community
4 An ensemble of simulations from different versions of the Community Atmosphere Model 5 (CAM) in the Community Earth System Model (CESM) is used to investigate the processes 6 responsible for the inter-model spread in climate sensitivity. In the CESM simulations, 7 the climate sensitivity spread is primarily explained by shortwave cloud feedbacks on the 8 equator-ward flank of the mid-latitude...
متن کاملThe Evolution of Climate Sensitivity and Climate Feedbacks in the Community Atmosphere Model
The major evolution of the National Center for Atmospheric Research Community Atmosphere Model (CAM) is used to diagnose climate feedbacks, understand how climate feedbacks change with different physical parameterizations, and identify the processes and regions that determine climate sensitivity. In the evolution of CAM from version 4 to version 5, the water vapor, temperature, surface albedo, ...
متن کاملA large ozone-circulation feedback and its implications for global warming assessments
State-of-the-art climate models now include more climate processes which are simulated at higher spatial resolution than ever1. Nevertheless, some processes, such as atmospheric chemical feedbacks, are still computationally expensive and are often ignored in climate simulations1,2. Here we present evidence that how stratospheric ozone is represented in climate models can have a first order impa...
متن کاملHow sensitive is climate sensitivity?
[1] Estimates of climate sensitivity are typically characterized by highly asymmetric probability density functions (pdfs). The reasons are well known, but the situation leaves open an uncomfortably large possibility that climate sensitivity might exceed 4.5°C. In the contexts of (1) global‐ mean observations of the Earth’s energy budget and (2) a global‐mean feedback analysis, we explore what ...
متن کاملUsing Relative Humidity as a State Variable 1 in Climate Feedback Analysis
5 An approach to climate change feedback analysis is described in which tropospheric relative 6 humidity replaces specific humidity as the state variable that, along with the temperature 7 structure, surface albedos and clouds, controls the magnitude of the response of global mean 8 surface temperature to a radiative forcing. Despite being simply a regrouping of terms 9 in the feedback analysis...
