The sensitivity of global climate with respect to forcing is generally described in terms of the global climate feedback—the global radiative response per degree of global annualmean surface temperature change.While the global climate feedback is often assumed to be constant, its value—diagnosed from global climate models—shows substantial time variation under transient warming. Here a reformul...

The robust weakening of the tropical atmospheric circulation in projections of anthropogenic warming is associated with substantial changes in regional and global climate. The present study focuses on understanding the response of the annual-mean Hadley circulation from a perspective of interactions between climate feedbacks and tropical circulation. Simulations from an ensemble of coupled ocea...

Abstract The variability of the zonal-mean large-scale extratropical circulation is often studied using individual modes obtained from empirical orthogonal function (EOF) analyses. prevailing reduced-order model leading EOF (EOF1) zonal wind, called annular mode, consists an eddy–mean flow interaction mechanism that results in a positive feedback EOF1 onto itself. However, few studies have poin...

In this paper, we propose a class of nonlinear bounded feedbacks for the stabilization of integrators chain that includes the previously existing result of Teel [1]. The main benefits of the proposed method are the significant performance improvement compared to Teel’s work and the global stabilization result obtained with possibly analytic feedbacks compared to the existing results focused on ...
