Gravity wave modulation of gradient drift instabilities in mid-latitude sporadic E irregularities
(American Geophysical Union, 1991-07)
Recent E region VHF backscatter echoes observed by the MU radar at mid-latitudes show quasiperiodic striations with a fairly constant range vs. time tilt in a RTI display. These features are explained in terms of gravity ...
Fourier homogenization method and the propagation of acoustic waves through a periodic vortex array
(1999)
The classical problem of homogenization of elliptic operators in arbitrary domains
with periodically oscillating coe cients is considered. As the period goes to zero, an asymptotic
analysis of the corresponding sequence ...
The Central Pacific El Niño intraseasonal Kelvin wave
(American Geophysical Union (AGU), 2014-10)
In this study, we document and interpret the characteristics of the IntraSeasonal Kelvin wave (ISKw) in the Pacific over the 1989–2011 period, based on observations, a linear model, and the outputs of an Ocean General ...
Synoptic analysis of a cold period in Bauru-SP in July 2015Análise Sinótica de um Período Frio Em Bauru - Sp em Julho de 2015
(2019-01-01)
The first ten days of July 2015 in Bauru, SP, presented low temperatures with a higher decline on day 05. The purpose of this study was to describe the atmosphere characteristics that led to this decline in air temperature ...
Estudo da propagação vertical das ondas de gravidade de pequena escala observadas na Estação Antártica Comandante Ferraz nos anos de 2015 a 2017
(Universidade Federal de Santa MariaBrasilMeteorologiaUFSMPrograma de Pós-Graduação em MeteorologiaCentro de Ciências Naturais e Exatas, 2020-12-09)
This dissertation had the objective of identification and analysis of the vertical propagation conditions and possible sources of the gravity waves observed over the Comandante Ferraz Antarctic Station (EACF: 62.1° S; 58.4° ...
Frequency tunable continuous THz wave generation in a periodically poled fiber
(Ieee-inst Electrical Electronics Engineers Inc, 2015-05-01)
An all-fiber approach to terahertz generation using a periodically poled optical fiber is proposed and experimentally demonstrated. In the proposed approach, a continuous-wave THz wave is generated at a periodically poled ...
