Zonal And Meridional
Zonal and meridional flow are directions and regions of fluid flow on a globe. Zonal flow follows a pattern along latitudinal lines, latitudinal circles or in the west–east direction. Meridional flow follows a pattern from north to south, or from south to north, along the Earth's longitude lines, longitudinal circles (meridian) or in the north–south direction. These terms are often used in the atmospheric and earth sciences to describe global phenomena, such as "meridional wind", or "zonal average temperature". In the context of physics, zonal flow connotes a tendency of flux to conform to a pattern parallel to the equator of a sphere. In meteorological term regarding atmospheric circulation, zonal flow brings a temperature contrast along the Earth's longitude. Extratropical cyclones in zonal flows tend to be weaker, moving faster and producing relatively little impact on local weather. Extratropical cyclones in meridional flows tend to be stronger and move slower. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zonal And Poloidal
In magnetic confinement fusion the zonal direction primarily connotes the poloidal direction (i.e. the short way around the torus), the corresponding coordinate being denoted by ''y'' in the slab approximation or ''θ'' in magnetic coordinates. However, in the fusion context, usage is restricted to the context of zonal plasma flows and there will in general be a toroidal component in such flows as well. Thus, although the term zonal has come into use in plasma physics to emphasize an analogy with zonal flows in geophysics, it does not uniquely identify the direction of flow, unlike the case in geophysics.

Zonal Polynomial
In mathematics, a zonal polynomial is a multivariate symmetric homogeneous polynomial. The zonal polynomials form a basis of the space of symmetric polynomials. They appear as zonal spherical functions of the Gelfand pairs (S_,H_n) (here, H_n is the hyperoctahedral group) and (Gl_n(\mathbb), O_n), which means that they describe canonical basis of the double class algebras \mathbb _n \backslash S_ / H_n/math> and \mathbb _d(\mathbb)\backslash M_d(\mathbb)/O_d(\mathbb)/math>. They are applied in multivariate statistics. The zonal polynomials are the \alpha=2 case of the C normalization of the Jack function In mathematics, the Jack function is a generalization of the Jack polynomial, introduced by Henry Jack. The Jack polynomial is a homogeneous, symmetric polynomial which generalizes the Schur and zonal polynomials, and is in turn generalized by ....

Interzonal
Interzonal chess tournaments were tournaments organized by the World Chess Federation FIDE from the 1950s to the 1990s. They were a stage in the triennial World Chess Championship cycle and were held after the Zonal tournaments, and before the Candidates Tournament. Since 2005, the Chess World Cup has filled a similar role. Zonal tournaments In the first year of the cycle, every FIDE member nation would hold a national championship, with the top players qualifying for the Zonal tournament. The world was divided into distinct zones, with the USSR, United States and Canada each being designated a zone, thus qualifiers from these three zones went directly to the Interzonal. Smaller countries would be grouped into a zone with many countries. For example, all of South America and Central America combined originally formed one zone. Interzonal tournaments The top players in each Zonal tournament would meet in the Interzonal tournament, which would typically have between 20 and ...
