Abstract Atmospheric circulation is a vital process in the transport of heat, moisture, and pollutants around globe. The variability rainfall depends to some extent on atmospheric circulation. This paper investigates synoptic situations southern Africa that can be associated with wet days dry Free State, South Africa, addition underlying dynamics. Principal component analysis was applied T-mode...

The formation of an island circulation is investigated both theoretically and numerically in light of the dynamics of coastal Kelvin waves and Rossby waves. An island circulation is formed in three stages. First, the direction of the circulation is initiated by the coastal Kelvin wave; second, the transport of the circulation is established by the short Rossby wave dissipated against the easter...

When a tracer substance which does not diffuse through the capillary walls is introduced into the brachial artery and the effluent blood is sampled continuously thereafter, a time-concentration curve of the labeled substance may be plotted which describes the velocity-flow pattern of the blood in the forearm ( 1) . It was found that the descending limb of the time-concentration curve usually wa...

PCG signal pattern classification, also known as auscultation pattern recognition, was one of the efficient computer-based methods applied to medical decision making. PCG Pattern recognition generally is interpreted in two ways. The most general definition includes recognition of patterns in any type of PCG dataset and is called uniform PCG pattern classification this discriminate peaks of hear...

At present, China’s external circulation is facing opportunities such as the diversification of foreign trade and investment opening a multi-level development pattern with Regional Comprehensive Economic Partnership. same time, challenges brought about by US Indo-Pacific Framework economic trends Japan ASEAN are also rising. Therefore, in face an increasingly complex international environment v...

We investigate the connection between the equatorial Madden-Julian Oscillation (MJO) and different types of the Northern Hemisphere mid-winter major stratospheric sudden warmings (SSWs), i.e., vortex-displacement and vortex-split SSWs. The MJO-SSW relationship for vortex-split SSWs is stronger than that for vortex-displacement SSWs, as a result of the stronger and more coherent eastward propaga...

Abstract Starting from the general, governing equations for a viscous, compressible fluid, with an associated description of its thermodynamics, we outline asymptotic derivation based on thin-shell approximation. [The details appear in another publication.] This produces reduced system which retain all dynamics and thermodynamics steady atmosphere, approximation alone being basis construction s...
