Analising the ageostrophic wind on 200hPa level during Meiyu period in July 1 - 13, 1991,it showed that the wind was mostly set up by momentum exchange of cumulus convection, by the wind advection next.
The upper air divergence of troposphere,positive vorticity advection and lowlevel southeast jet make the mechanism responsible for the system's occurrence and development and the latent heat of condensation released from the convection contributes greatly to a further development and strengthening of it.
Three cases of the southwesterly low-level jet stream during the Meiyu season have been analyzed,showing that the kinetic energy of the jet stream is generated by the kinetic energy production of the divergence wind and the effect of the cumulus convection. The main physical factors affecting the rate of divergence wind kinetic energy production are latent heating, temperature advection and the role of the divergence term in the ω equation.
When the cold and warm advection is weak, the power-ful cumulus convection causes the south wind in the vicinity of the vortex and the nega-tive vorticity east of the vortex to increase, thus inhibiting the eastward motion of thevortex.
Radiative heat transfer in solids and convective heat transfer between the gas and the solid is especially studied.
Methods and algorithms of numerical simulation for three-dimensional thermal-convective motions of the inhomogeneous high-viscosity incompressible fluid in the direct and inverse time are described.
It is shown that, for univalent cations in the regime of convective diffusion, the coefficient of electrolyte rejection by the membrane correlates with the adsorption potential of cations (counterions) at the pore surface of a selective layer.
The gel-layer accumulates considerable surface and bulk charges and is characterized by the high hydraulic resistance hindering the convective ion transport.
It is shown that the effective mechanism of the saturation of nanocrystalline materials with impurities is their convective transfer by moving macrodislocations-linear defects of the regular packing of nanograins.
The downward advection of trophogenic waters was found to create conditions for the extensive growth of microorganisms capable of decomposing and mineralizing organic carbon, nitrogen, and phosphorus in deep water layers.
The mixing of the seawater and groundwater occurs as a result of advection processes, the most important of which is wave percolation.
The equation of advection-diffusion transport of a reactive solute in a stream is solved by different methods.
A simple procedure is proposed for predicting this concentration based on an advection-diffusion model and field observational data.
Equations of flow in water-saturated porous medium and advection diffusion of dissolved salts are used to study salt transport and accumulation in subsoil water.
Numerical analysis of thermal convections in a three-dimensional cavity: Influence of difference in approximation models on nume
The behavior of the critical temperature gradient is discussed in terms of various parameters of the system for both stationary and overstable convections.
Convections over Indo-China Peninsula and its surrounding areas further increase after the splitting.
UHI induced local air convergence and initiated the thunderstorm convections.
This isotopic constancy is incompatible with multiple, small, independent hydrothermal cells of the East Pacific Rise type, and fits much better with a model of hydrothermal convections driven by "magmatic floor heating".
