Tiros Vortices and Large - Scale Vertical Motion
TIROS cloud photographs and fine-scale quasi-geostrophic calculations of vertical motion are used in an attempt to gain understanding of the evolution of vortices and other aspects of large-scale cloud masses and to explore the usefulness of the pictures in diagnosis of the vertical motions. Horizontal and vertical motions are found to be of roughly equal importance in the cvolution of cloud pa...
متن کاملModulation analysis of large-scale discrete vortices.
The behavior of large-scale vortices governed by the discrete nonlinear Schrödinger equation is studied. Using a discrete version of modulation theory, it is shown how vortices are trapped and stabilized by the self-consistent Peierls-Nabarro potential that they generate in the lattice. Large-scale circular and polygonal vortices are studied away from the anticontinuum limit, which is the limit...
متن کاملCharacteristic parameters of drift vortices coupled to Alfvén waves in an inhomogeneous space plasma.
We present detailed measurements of ion scale vortices of drift type coupled to Alfvén waves in an inhomogeneous and collisionless space magnetoplasma. The two free parameters of a dipolar vortex, intensity and spatial radius, are measured. The vortices are driven by a strong density gradient on a boundary layer with scale size of the same order as the vortex diameter. Observations of vortices ...
متن کاملLarge-scale Vortices in Protoplanetary Disks: On the observability of possible early stages of planet formation
We investigate the possibility of mapping large-scale anti-cyclonic vortices, resulting from a global baroclinic instability, as pre-cursors of planet formation in proto-planetary disks with the planned Atacama Large Millimeter Array (ALMA). On the basis of three-dimensional radiative transfer simulations, images of a hydrodynamically calculated disk are derived which provide the basis for the ...
متن کاملAn Experimental Technique for the Generation of Large-Scale Spanwise Vortices in a Wind Tunnel
The presence of large-scale vortices with high spanwise coherence has been observed in the atmospheric boundary layer (ABL). This study investigates an innovative technique to generate a large-scale spanwise vortex from the oscillation of a surface-mounted fence in a wind tunnel. Characteristics of the large vortex with a well-defined length scale and its development with downstream distance be...
