The storm first appeared at 15: 00, then moved to the southeast direction , from 16: 15 to 17: 03, the multi-cell storm became more strongly and evolved into the supercell storm with the characteristics of the vortex zonal echoes and band echo.
2)The spherical function spectrum structure of 500hPa hemispherical climatic fields is simple,and the fields are mainly composed of ultra-long waves(0≤ m,k ≤3; m,k not equal to 0 simultaneously),specially of zonal spherical function( m =0),thus showing a low order and dimension on feature.
Sea level pressure anomalies over East Asia in winter will be confined within -1.0hPa to 0.4hPa and exhibit a zonal band-shape distribution, with the positive (negative) values in south (north) parts.
in sea surface temperature field, there is a zonal negative(positive) anomaly in equatorial central and eastern Pacific and positive(negative) one in original region of the North West Pacific Ocean TC and the northwest Pacific Ocean.
The solution of coupling equation reveals that the finite-amplitude disturbance wave ensemble can be completely transferred into the zonal mean flow by nonlinear resonance interaction in rotating barotropic atmosphere. The energy transfer process would continue until the motion become pure zonal flow. It.
Analysis of the variation of the EAWJ horizontal structure shows that the zonal wind at 200 hPa along 40°N from 100°E to 120°E is weakened while the zonal wind at 200 hPa is strengthed from Bay of Bengal to South China area.
Quantum Symmetric Pairs and Their Zonal Spherical Functions
例句来源
We study the space of biinvariants and zonal spherical functions associated to quantum symmetric pairs in the maximally split case.
例句来源
As a consequence, there is either a unique set, or an (almost) unique two-parameter set of Weyl group invariant quantum zonal spherical functions associated to an irreducible symmetric pair.

These examples have an interpretation in the setting of radial functions on Rd and zonal functions on compact two-point homogeneous spaces, where they provide a new transform which possesses many properties of the classical Gabor transform.

In the summer half year,the average intensity of the Pacific high pressurechanges more or less abruptly.It strongly increaseses from June to July and de-creases gradually from April to June.In middle September it decreasees suddenly. In.the summer season(from June to August),tha advance and retreat of theWestern Pacific pressure ridge(moving from east to west or reversed)is intimatelycorrelated with teh upper westerlies.At the same time,the Pacific High itselfis an important factor of the atmospheric circul...
Integrating with respect to time the equation for the balance of angular momentum of the atmosphere north of certain latitude (30°N say)we obtainIn the above equation ρ is thedensity; (?), the zonal wind; v, the meridional wind; R, the earth's radius; Ω, the angular speed-of the earth's rotation; dm, the mass element of the atmosphere; dτ, the volume element; ds, the area element on the earth's surface, and dσ, the urea element on the vertical surface over the latitudial circle of 30°N. The first two ...
Utilizing the latitudinal mean ot upper meridional wind of 1950 given by Buch and Starr and White, mean meridional circulation has been studied. Fig. 1-3 (fig. 1 for whole year, fig. 2 for winter, fig. 3 for summer) reveal three cells: two direct cells in low and high latitudes respectively and one indirect cell in middle latitudes. The average jet stream of 1950 is situated in the middle cell. The yearly average equatorial convergence zone is at about 5°N. From winter to summer all the three cells shift no...
