Morphology of the postsunset vortex in the equatorial ionospheric plasma drift
(American Geophysical Union, 2014-12-09)
The postsunset vortex in the equatorial ionosphere exhibits clockwise plasma motions after sunset in longitude (time) and altitude coordinates when the equatorial ionosphere is viewed looking northward. We describe the ...
Possible ionospheric preconditioning by shear flow leading to equatorial spread F
(European Geosciences Union (EGU), 2005-10-14)
Vertical shear in the zonal plasma drift speed is apparent in incoherent and coherent scatter radar observations of the bottomside F region ionosphere made at Jicamarca from about 1600–2200 LT. The relative importance of ...
Reduction of chaotic particle transport driven by drift waves in sheared flows
(AMER INST PHYSICS, 2008)
Investigations of chaotic particle transport by drift waves propagating in the edge plasma of tokamaks with poloidal zonal flow are described. For large aspect ratio tokamaks, the influence of radial electric field profiles ...
Precipitation and circulation covariability in the extratropics
(2006-09)
Extratropical precipitation is primarily produced by cold and warm fronts associated with surface cyclones and upper-level troughs. The growth of these midlatitude storms is partially controlled by the dry baroclinicity ...
Effective transport barriers in nontwist systems
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
In fluids and plasmas with zonal flow reversed shear, a peculiar kind of transport barrier appears in the shearless region, one that is associated with a proper route of transition to chaos. These barriers have been ...
A Climate Feature of the Tropical Americas: The Trade Wind Easterly Jet
(1998-06)
Utilizando datos medios mensuales globales de los Reanálisis de NCEP/NCARP para el periodo 1982-1994 se documenta una característica de la circulación de las Américas tropicales no reportada hasta el momento en la literatura: ...

Internal inertia-gravity waves in the tropical lower stratosphere observed by the Arecibo Radar
(American Meteorological Society, 1984-08-01)
High-resolution upper tropospheric and lower stratospheric (5-30 km) wind data were obtained during three periods from 1979 to 1981 with the aid ofthe high-power UHF radar at Arecibo, Puerto Rico (18.4°N, 66.8°W). A ...
Effects of large horizontal winds on the equatorial electrojet
(American Geophysical Union, 2002-08)
The effects of large winds on the low-latitude E region ionosphere and the equatorial electrojet in particular are analyzed theoretically, computationally, and experimentally. The principles that govern the relationship ...
