The Transition to Superrotation in Terrestrial Atmospheres [PDF]
, 2010 We show that by changing a single non-dimensional number, the thermal Rossby number, global atmospheric simulations with only axisymmetric forcing pass from an Earth-like atmosphere to a superrotating atmosphere that more resembles the atmospheres of ...

Frontal Wind Field Retrieval Based on UHF Wind Profiler Radars and S-Band Radars Network
Atmosphere, 2019 The three-dimensional wind field (WPR3D) and the multiple WPR3D (M-WPR3D) associated with the passage of a stationary front was derived from observations made by a network of eight wind profiler radars (WPR) being operated by the Korea Meteorological ...

Direct numerical simulation of gas transfer across the air-water interface driven by buoyant convection [PDF]
, 2015 A series of direct numerical simulations of mass transfer across the air-water interface driven by buoyancy-induced convection has been carried out to elucidate the physical mechanisms that play a role in the transfer of heat and atmospheric gases.

Earth, Planets and Space, 2023 We have studied the convective (or static) and dynamic instabilities between 80 and 100 km above Tromsø (69.6° N, 19.2° E) using temperature and wind data of 6 min and 1 km resolutions primarily almost over a solar cycle obtained with the sodium lidar at

Thermal instability and evaporation of accretion disc atmospheres [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We investigate the thermal stability of the outer layers of accretion discs in which the local viscous energy dissipation rate scales with the pressure as for standard Shakura-Sunyaev discs. By solving for the accretion disc vertical structure using the grey two-stream approximation, we show that the thermal structure of the optically thin outer layers

Variation in Extreme Temperature and Its Instability in China
Atmosphere, 2021 In this study, the instability of extreme temperatures is defined as the degree of perturbation of the spatial and temporal distribution of extreme temperatures, which is to show the uncertainty of the intensity and occurrence of extreme temperatures in ...

Analysis of IUE spectra of helium-rich white dwarf stars [PDF]
, 2006 We studied the class of DB white dwarf stars, using re-calibrated UV spectra for thirty four DBs obtained with the IUE satellite. By comparing the observed energy distributions with model atmospheres, we simultaneously determine spectroscopic distances ...

3D Model Atmospheres for Extremely Low-Mass White Dwarfs [PDF]
, 2015 We present an extended grid of mean three-dimensional (3D) spectra for low-mass, pure-hydrogen atmosphere DA white dwarfs (WDs). We use CO5BOLD radiation-hydrodynamics 3D simulations covering Teff = 6000-11,500 K and logg = 5-6.5 (cgs units) to derive ...
