Relative effects of electric field and neutral wind on positive ionospheric storms
(SpringerOpen, 2009-05-14)
The paper studies the relative importance of penetrating eastward electric field (PEEF) and direct effects of equatorward neutral wind in leading to positive ionospheric storms at low-mid latitudes using observations and ...
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 ...
Correlative study of neutral winds and scintillation drifts measured near the magnetic equator
(American Geophysical Union, 2002-07-18)
Measurements of the thermospheric neutral wind at Arequipa, Peru, and observations of the drift of the irregularities at Ancon, Peru, are used to study the coupling that exists between ions and neutrals at equatorial ...
Three-Dimensional Wind Measurements and Modeling Using a Bi-Static Fabry-Perot Interferometer System in Brazil
(University of Illinois at Urbana-Champaign, 2013)
The earth’s upper atmosphere has been studied for over a century now, and while a multitude of data has been collected studying the plasma in the ionosphere, there are not equivalent amounts of data on neutrals in the ...
Wind tunnel experiments with neutral and convective boundary layer stabilities
(Scientific & Academic Publishing, 2018)
The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. ...
Employing wind tunnel data to evaluate a turbulent spectral model
(Science Publishing Group, 2016)
In this study, spectra obtained from wind tunnel data are compared with a model that describes observed
atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for ...
Comparison of zonal neutral winds with equatorial plasma bubble and plasma drift velocities
(American Geophysical Union, 2013-03-20)
A one-year dataset spanning March 2011-March 2012 of coincident observations of night time thermospheric zonal neutral winds, equatorial plasma bubble (EPB) velocities, and zonal plasma drifts are used to examine the ...
Remote sensing lower thermosphere wind profiles using non-specular meteor echoes
(American Geophysical Union, 2009-05-12)
This article describes a new method of measuring wind velocity profiles between 93 km and 110 km altitude by tracking non‐specular meteor echoes as neutral winds transport the plasma trails. This requires a large VHF radar ...
PCA and vTEC climatology at midnight over mid-latitude regions
(Springer, 2017-12)
The effect of the thermospheric vertical neutral wind on vertical total electron content (vTEC) variations including longitudinal anomaly, remaining winter anomaly, mid-latitude summer night anomaly, and semiannual anomaly ...
Reprocessing of data from Fabry-Perot interferometers (FPI) belonging to the IGP network of optical instruments
(Instituto Geofísico del Perú, 2021-06)
IGP network of optical instruments consist of two types of imaging instrumentation: Fabry-Perot Interferometers (FPI) and All-Sky imagers (ASI). The FPI can obtain two dimensional interferograms that are used to study the ...
