The smoothed finite element method (S-FEM) was originated by G R Liu by combining some meshfree techniques with the well-established standard finite element method (FEM). It has a family of models carefully designed with innovative types of smoothing domains. These models are found having a number of important and theoretically profound properties. This article first provides a concise and easy-to-follow presentation of key formulations used in the S-FEM. A number of important properties and unique features of S-FEM models are discussed in detail, including 1) theoretically proven softening effects;2) upper-bound solutions;3) accurate solutions and higher convergence rates;4) insensitivity to mesh distortion;5) Jacobian?free;6) volumetric-locking-free;and most importantly 7) working well with triangular and tetrahedral meshes that can be automatically generated. The S-FEM is thus ideal for automation in computations and adaptive analyses, and hence has profound impact on Al-assisted modeling and simulation. Most importantly, one can now purposely design an S-FEM model to obtain solutions with special properties as wish, meaning that S-FEM offers a framework for design numerical models with desired properties. This novel concept of numerical model demand may drastically change the landscape of modeling and simulation. Future directions of research are also provided. 展开更多

In this paper the impacts of the anomalous SST in the warm pool area of the Western Equatorial Pacific on the winter time circulation and the East Asian monsoon are studied by using the NCAR CCM. It is found that the abnormal heating in the warm pool area will change the strength and the position of the Walker Cell in the Equatorial Pacific and the anti-Walker Cell in the equatorial Indian Ocean. Both the Walker and anti-Walker Cells are strengthened. The local Hadley Cells over two hemispheres near the warm pool are also strengthened. The subtropical highs in two hemispheres become stronger and move poleward slightly. The westerly jets in the extratropical regions have similar changes as the subtropical highs. The winter monsoon in South-East Asia is weakened by the abnormal heating in the warm pool. The experiment also show that there are wave trains emanating from surrounding areas of the warm pool to the high latitudes, causing various changes in circulations and local weather. 展开更多

The general form of the dynamic response of a controlled process is shown in Fig. 1, where E is the deviation of the controlled variable U from its set-point value U<sub>0</sub> (i. e. E= U<sub>0</sub>-U). For convenience in discussing, we transform the curve in Fig. 1 into that in Fig. 2 a t-domain curve of |E|. Now, we discuss a certain period of variation of the curve in Fig. 2, e.g. a time interval between to and t<sub>4</sub>.We partition this period of variation into four subintervals: t<sub>0</sub>—t<sub>1</sub>, t<sub>1</sub>—t<sub>2</sub>, t<sub>2</sub>—t<sub>3</sub> and t<sub>3</sub>—t<sub>4</sub>.

A barotropic channel model in β-plane is used to study the effect of topographic forcing on the formation and maintenance of blocking. The approximate analytical solution of potential vorticity equation can show the main property of the whole process of blocking. It is indicated that the topographic forcing is one of the main factors causing the blocking process. The results suggest that the nonlinear interaction plays a very important role in the stable "Ω" situation of blocking. The atmospheric circulation with periodic and low-frequency oscillation, perhaps, is partly caused by topographic forcing. 展开更多

Based on a series of data analyses, the intimate relations between anomalous winter monsoon in East Asia and El Nino arc studied in this paper.Anomalistic circulation in the Northern Hemisphere caused by El Nino event can lead to enhancing the Ferre! cell and the westerlies in the mid-latitudes as the Hadley cell and result in the location of the front zone in East Asia to the north. These are unfavourable for the cold wave breaking out southward in East Asia. Therefore, there ate warmer weather and weaker winter monsoon in East Asia in El Nino winter.There are stronger and frequent cold waves in East Asia during the wintertime prior to the occurrence of El Nino event. They will induce stronger winter monsoon in East Asia. Thus, the weakened trade wind and enhanced cumulus convection in the equatorial middle-western Pacific area caused by the stronger winter monsoon will play an important role in the occurrence of El Nino event. Therefore, the anomalously strong winter monsoon in East Asia during winter 展开更多

In terms of the expansion by extended empirical orthogonal function (EEOF) with data of ECMWFWMO and of outgoing longwave radiation(OLR) furnished by the NOAA polar-orbiting satellite,a study ismade of November 1981 to March 1982 low-frequency (30--60 day)summer monsoon activity in the Indone-sian-North Australian zone (INAZ) together with its relation to atmospheric circulations in the Northern andSouthern Hemispheres. Results show that at 850 hPa the southward blowing low-frequency NE(SW)wind from the eastern Asiancoast changes, after crossing the euqator, to summer NW (SE) monsoon in the INAZ, which, when convergingwith (diverging from) the western-Australian enforced low-frequency SW (NE) wind, brings about strengthened(weakened) convection in the summer monsoon area and its eastward advance, with corresponding low-frequency variation shown in 850 hPa geopotential height. These outcomes are similar to those from the studyof non-filtered actual observations, leading to the conclusion that the component of low-frequency variationillustrates major features characteristic of the variation in the tropical circulation. 展开更多

It is the presence of weakened intercalations that makes the foundation ofGezhouba Erjiang-Sluice complex. Seepage control installation must be able not onlyto reduce seepapge pressure, but also to protect weakened intercalations fromencroachment of seepage. In this paper theoretical analysis has been conducted toprove that well system is highly effective seepage control installation meeting thisdemand. By means of in-situ monitoring it has been verified that proposed seepagecontrol measure relying mainly on drainage is of success. Seepage stability ofweakened intercalations must be considered in employing drains to control seepage,while the seepage deformation of weakened intercalations is different from that ofordinary sand-gravel. Mechanism of seepage deformation of weakened intercalations hasbeen expounded. Seepage wedging is a special type of seepage deformation for weakenedintercalations, It is shown clearly that seepage deformation of intercalations doesnot mean seepage failure of the foundation. In such a foundation as that of Gezhoubasluice, the permeability is distributed randomly. So the seepage field is anunstable, stochastic field. 展开更多

Non-acceleration theorem in a primitive equation system is developed to investigate the influences of waves on the mean flow variation against external forcing. Numerical results show that mechanical forcing overwhelms thermal forcing in maintaining the mean flow in which the internal mechanical forcing associated with horizontal eddy flux of momentum plays the most important roles. Both internal forcing and external forcing are shown to be active and at the first place for the mean flow variations, whereas the forcing-induced mean meridional circulation is passive and secondary. It is also shown that the effects on mean flow of external mechanical forcing are concentrated in the lower troposphere, whereas those due to wave-mean flow interaction are more important in the upper troposphere. These act together and result in the vertically easterly shear in low latitudes and westerly shear in mid-latitudes. This vertical shear of mean flow is to some extent weakened by thermal forcing. 展开更多
