, 2018 We investigate the possibility that sufficiently large electric fields and/or ionization during geomagnetic disturbed conditions may invalidate the assumptions applied in the retrieval of neutral horizontal winds from meteor and/or lidar measurements. As

Sensitivity studies of the E region neutral response to the postmidnight diffuse aurora [PDF]
Annales Geophysicae, 2006 Measurements of the neutral thermosphere within the postmidnight substorm recovery phase diffuse aurora show very large horizontal winds, and strong vertical structure.

Energies, 2023 Wind energy production mainly depends on atmospheric conditions. The atmospheric stability can be described through different parameters, such as wind shear, turbulence intensity, bulk Richardson number, and the Monin–Obukhov length.

Starburst Driven Galactic Superbubbles Radiating to 10 K [PDF]
, 2016 Our three-dimensional hydro-dynamical simulations of starbursts examine the formation of superbubbles over a range of driving luminosities and mass loadings that determine superbubble growth and wind velocity.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Dependence of daytime thermospheric winds on IMF By as measured from south pole
Frontiers in Astronomy and Space SciencesWinds in the nighttime upper thermosphere are often observed to mimic the ionospheric plasma convection at polar latitudes, and whether the same is true for the daytime winds remains unclear.

Multi‐Instrument Observations of Ion‐Neutral Coupling in the Dayside Cusp
Geophysical Research Letters, 2020 Using data from the Scanning Doppler Imager, the Super Dual Auroral Radar Network, the EISCAT Svalbard Radar, and an auroral all‐sky imager, we examine an instance of F region neutral winds which have been influenced by the presence of poleward moving ...

Numerical modeling of solar wind influences on the dynamics of the high-latitude upper atmosphere [PDF]
Advances in Radio Science, 2012 Neutral thermospheric wind patterns at high latitudes obtained from cross-track acceleration measurements of the CHAMP satellite above both polar regions are used to deduce statistical neutral wind vorticity distributions and were analyzed in their ...

Monthly Variation of Thermospheric Neutral Winds
, 2022 Earth’s atmosphere is commonly divided into different layers based on the change of temperature with altitude. The thermosphere is a part of the atmosphere characterized by a dramatic increase in temperature with altitude starting at about 100 km in altitude.

Coherence of Turbulent Wind Under Neutral Wind Conditions at FINO1
Energy Procedia, 2016 AbstractCurrent wind turbine design standards allow for two different approaches to model the wind field used for engineering estimates; The Mann turbulence model and the Kaimal wind spectra combined with a coherence function. The point wind spectra generated, using the recommended parameters, are similar, but there are differences in the spatial ...
