Abstract: Using NCEP?NCAR reanalysis data, decadal trends in planetary wave activity in Northern Hemisphere high latitudes (50°?90°N) in late winter and early spring (January?February?March) were studied. Results show that wave ...

Abstract: Using NCEP?NCAR 51-yr reanalysis data, the interannual and decadal variations of planetary wave activity and its relationship to stratospheric cooling, and the Northern Hemisphere Annular mode (NAM), are studied. It is ...

Abstract: This paper is a continuation of the study of the advection?diffusion problem for stratospheric flow, and deals with the probability distribution function (PDF) of gradients of a freely decaying passive tracer. Theoretical ...

Abstract: his study investigates the climate dynamic feedbacks during a transition from the present climate to the extremely cold climate of a ?Snowball Earth? using the Community Climate System Model, version 3 (CCSM3). With the ...

Abstract: he ?Snowball Earth? hypothesis, proposed to explain the Neoproterozoic glacial episodes in the period 750?580 million years ago, suggested that the earth was globally covered by ice/snow during these events. This study ...

Abstract: Decadal trends are compared in various fields between Northern Hemisphere early winter, November?December (ND), and late-winter, February?March (FM), months using reanalysis data. It is found that in the extratropics and ...

Abstract: AbstractRegional sea surface temperature (SST) mode variabilities, especially the La Niña?like Pacific Ocean temperature pattern known as the negative phase of the interdecadal Pacific oscillation (IPO) and the associated ...

Abstract: A slowdown in the rate of surface warming in the early 2000s led to renewed interest in the redistribution of ocean heat content (OHC) and its relationship with internal climate variability. We use the Community Earth ...
