This paper is the second part of the author's papers, in the present paper, envelope solitary Rossby waves in the rotating barotropic atmosphere were deeply investigated, it is found that when Rossby wavenumber m(m is the zonal wavenumber) satisfies 1blocking high structure.
Analyzed a case of severe shear line in Xinjiang in March in 1998, it is shown that Mongolia blocking anticyclone act decisively on the shear line; the shear line is a cold wind convergence zone, which is weaker in the day than at night.
The establishment of a blocking anticyclone in the mid-higher latitude, the strong and the stable westerly jet in the middle latitude and the abnormal actively convective in the tropical region are conducive to the relative stability of the WPSA.
In the second place, the climate characteristics of Okhotsk blocking, Baikal blocking and Ural blocking are particularly analyzed. These blockings have a important relationship with atmospheric circulation and China summer rainfall.
It is shown that the three key blockings obviously take on annual and staggered variation , and the establish and maintenance of the blocking in the east of Asia will lead to divarication of west wind circulation, so that their southern frontal zone move southward and subtropical high move southward a little, so there is plentiful rainfall in the middle and lower reaches of Changjiang River in summer.
Based on the ray theory of geometric optics, study is made of the effects of blockings on the dispersion of Rossby waves, together with the shielding of blockings in the Rossby waves propagation, thereby interpreting why Rossby waves in the regions under the control of certain blockings can hardly be propagated and maintained.
Aimed at stud of atmospheric free mode and blocking high, firstly, the relationships between blockings and China summer rainfall are clarified, and the 500 hPa height in the summer of 1998 are detailed analysed.
Analysis of the contribution of the interlayer flows to the water flooding of low-permeability formation intervals calls into question the practicability of blocking high-permeability inclusions in the neighborhood of pumping wells.
For the solitary wave, two factors are very important: one is spherical effect of the disturbance and the other is meridional shear of blocking high.
Numerical study of ural blocking high's effect upon Asian summer monsoon circulation and East China flood and drought
The instantaneous total streamfunction fields of the topographically forced planetary-scale soliton are found to bear remarkable resemblance to the initiation, maintenance and decay of observed omega-type blocking high and dipole blocking.
The soliton perturbation theory is used to examine the role of a wavenumber-two topography in near-resonantly forcing omega-type blocking high and dipole blocking.
Calculational formulas for stationary probabilities of network resource blockings were obtained.

Experimental results show that the throughput for such systems with the new scheduling strategies can increase on an average of 7% by decreasing no-inputs and blockings compared with that of the traditional strategies.
Slumps and slides occur with contrasting backscatter, rough surface textures, blockings, and acoustic shadows at head walls.
