Sensitivity of idealized mixed‐phase stratocumulus to climate perturbations

Mechanisms of Marine Low Cloud Sensitivity to Idealized Climate Perturbations: A Single- LES Exploration Extending the CGILS Cases

Climate change sensitivities of subtropical cloud-topped marine boundary layers are analyzed using large-eddy simulation (LES) of three CGILS cases of well-mixed stratocumulus, cumulus under stratocumulus, and shallow cumulus cloud regimes, respectively. For each case, a steadily forced control simulation on a small horizontally doublyperiodic domain is run 10-20 days into quasi-steady state. T...

Sensitivity of climate forcing and response to dust optical properties in an idealized model

[1] An idealized global climate model is used to explore the response of the climate to a wide range of dust radiative properties and dust layer heights. The top-of-the-atmosphere (TOA) shortwave forcing becomes more negative as the broadband shortwave single scattering albedo increases and the broadband shortwave asymmetry parameter decreases, but the sensitivity is highly dependent on the loc...

Climate model attractors: chaos, quasi-regularity and sensitivity to small perturbations of external forcing

In this paper we discuss some theoretical results obtained for climate models (theorems for the existence of global attractors and inertial manifolds, estimates of attractor dimension and Lyapunov exponents, symmetry property of Lyapunov spectrum). We define the conditions for “quasiregular behaviour” of a climate system. Under these conditions, the system behaviour is subject to the Kraichnan ...

Simulated ENSO Sensitivity to Climate

This chapter examines the sensitivity of tropical Pacific interannual variability to changes in the climatological background state. Chapter 5 showed that although a wide variety of climate perturbations can affect the equatorial Pacific, the equatorial structure of the response tends to be similar in each case. Due to strong coupled feedbacks like those active in ENSO, the Pacific climatology ...
