The quasi-biennial oscillation (QBO) in the equatorial lower stratosphere has been well simulated first version of Center for Climate System Research/National Institute Environmental Studies (CCSR/NIES) atmospheric general circulation model (Takahashi, 1996). horizontal resolution is T21 with 60 layers vertical about 500m upper troposphere and stratosphere, a moist convective adjustment scheme. period 1.5 years, which slightly shorter than that observed.The wave behavior examined using...
Abstract The Arctic Oscillation/Northern Hemisphere annular mode (AO/NAM) is attributed to wave–mean flow interaction over the extratropical region of Northern Hemisphere. This closely related three atmospheric centers action, corresponding regional oscillations: NAO, PNA, and stratosphere polar vortex (SPV), respectively. It then natural infer that local interactions at these action are dynamically coupled each other can thus explain main aspects three-dimensional coherent structure mode,...
Abstract Studies on the nonlinear natures of spatiotemporal structure Arctic Oscillation/Northern Hemisphere annular mode (AO/NAM) in context interaction among North Atlantic Oscillation (NAO), Pacific–North American pattern (PNA), and stratospheric polar vortex (SPV) are performed. The non-Gaussianity multivariate probability density function (PDF) phase space spanned by their indices is examined first. Five local maxima potentially related to circulation regimes identified from so-called...
Abstract. By introducing an appropriately-defined imbalanced vortical flow as the basic state, our previous study has extended conventional instability theories of balanced flows for meso-scale convection. It considered not only apparent state but also two-way interaction between convection/IGWs and this imbalance. This paper reports new progresses such framework. A regular perturbation method on nonlinear case is performed to have insight into triggering mechanism seems convection can be...
This paper describes a numerical study of the role zonally symmetric normal modes in dynamics Arctic Oscillation (AO) or Northern Hemisphere Annular Mode (NAM)with seasonally varying climatological fields. Ageneral theory mechanism for mode selection involving fully developed non-linear interaction between different is proposed, and this explains not only prominence AO/NAM Hemisphere, but also existence Antarctic (AAO) Southern Hemisphere. Following mechanism, with spatial structures...
Theoretical studies usually attribute convections to the developments of instabilities such as static or symmetric basic flows.However, following three facts make validities these theories unconvincing.First, it seems that in most cases flow with balance property cannot exist exact solution, so one formulate appropriate problems stability.Second, neither linear nor nonlinear dynamical instability are able describe a two-way interaction between convection and its background, because state...

By applying a seasonally modulated condensation heating on tropical Kelvin waves with certain form of damping, the parametric instability and super (sub) harmonic response are investigated. It is suggested that excitation intraseasonal oscillation tropospheric QBO may be related to superharmonic subharmonic resonances seasonal cycle, respectively. The main features spatial structures propagation these resonant modes were shown compared those examine this point view.
As one of the key technologies IoT network, RFID has been widely applied in many areas, such as warehouse management, logistics tracking, pharmaceutical monitoring and so on. In this work, we focus on solving efficient reliable tag identification under capture effect. We proposed a aware splitting tree (CST) protocol build up model for passive UHF systems. Both theoretical analysis simulation comparisons are presented to demonstrate effectiveness protocol. Compared with existing works, CST...
