A laboratory model of Saturn’s North Polar Hexagon
A hexagonal structure has been observed at 76 N on Saturn since the 1980s (Godfrey, D.A. [1988]. Icarus 76, 335–356). Recent images by Cassini (Baines, K., Momary, T., Roos-Serote, M., Atreya, S., Brown, R., Buratti, B., Clark, R., Nicholson, P. [2007]. Geophys. Res. Abstr. 9, 02109; Baines, K., Momary, T., Fletcher, L., Kim, J., Showman, A., Atreya, S., Brown, R., Buratti, B., Clark, R., Nicho...
متن کاملPerturbing a Product of Stable Flows
Suppose that f and f ′ are axiom A flows with attractors A and A′. Then the attractor A×A′ for the product flow gt = ft×f ′ t on the product manifold is no longer hyperbolic (although there is a hyperbolic action of R2). It is easy to see that the attractor cannot explode but we show here that it cannot implode: for any flow (ht) sufficiently close to (gt) any attractor whose basin is not too t...
متن کاملA climatology of stratospheric polar vortices and anticyclones
[1] United Kingdom Meteorological Office global analyses from 1991 to 2001 are used to create a global climatology of stratospheric polar vortices and anticyclones. New methodologies are developed that identify vortices in terms of evolving three-dimensional (3-D) air masses. A case study illustrates the performance of the identification schemes during February and March of 1999 when a merger o...

15 صفحه اولfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
