TL;DR: In this article, an updated analysis of observed stratospheric temperature variability and trends is presented on the basis of satellite, radiosonde, and lidar observations, with some differences in detail among the different radiosonde and satellite data sets.

TL;DR: In this paper, the authors describe the main differences in simulations of stratospheric climate and variability by models within the fifth Coupled Model Intercomparison Project (CMIP5).

TL;DR: A series of numerical experiments on the forced two-dimensional turbulence on a rotating sphere were done to investigate the formation processes of zonal band structures and their sensitivity to two experimental parameters of the rotation rate and the forcing wave number as mentioned in this paper.

TL;DR: A series of numerical experiments on the decaying two dimensional turbulence was performed for a nondivergent barotropic fluid on a rotating sphere by using a high-resolution spectral model with a triangular truncation of T85.

TL;DR: Finite-time Lyapunov stability analysis is reviewed and applied to a low-order spectral model of barotropic flow in a midlatitude β channel as mentioned in this paper, which is used to investigate the growth of small perturbations superposed on a reference solution for a prescribed time interval.
