Deductive reconstruction of MLT* for multi-level modeling

, 2020
In the last two decades, about a dozen proposals were made to extend object-oriented modeling by multiple abstraction levels. One group of proposals designates explicit levels to objects and classes.

Twists in the flow: Revisiting convective mixing in rotating stellar models

Astronomy & Astrophysics
Context. Convection and rotation are both key processes in stellar evolution modelling. While standard mixing-length theory (MLT) provides a widely used modelling of convection, it neglects the effects of rotation on convective transport. Aims.

Diurnal and Seasonal Variation of High-Frequency Gravity Waves at Mohe and Wuhan

Atmosphere, 2022
Using the meteor radar data at the Mohe (53.5° N, 122.3° E) and Wuhan (30.5° N, 114.2° E) regions over China, this paper conducts a study on the diurnal and seasonal variation of high-frequency (within 2 h) gravity waves (GWs) activity in the mesosphere ...

Semi-annual oscillation (SAO) of the nighttime ionospheric D region as detected through ground-based VLF receivers [PDF]

Atmospheric Chemistry and Physics, 2016
Earth's middle and upper atmosphere exhibits several dominant large-scale oscillations in many measured parameters. One of these oscillations is the semi-annual oscillation (SAO). The SAO can be detected in the ionospheric total electron content (TEC),

Multiple, discrete arcs on sunward convecting field lines in the 14‐15 MLT region [PDF]

Journal of Geophysical Research: Space Physics, 1994
Ionospheric plasma flow measurements and simultaneous observations of thin (∼0.2° invariant latitude (ILAT)), multiple, longitudinally extended auroral arcs of transient nature within 74°‐76° ILAT and 1030‐1130 UT (∼14‐15 MLT) on January 12, 1989, are reported.

Occurrences of VLF Hiss and Saucer Emissins in the Southern Polar Region (c. Wave-Particle Interactions in the Magnetosphere) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

Antarctic Record, 1980
Satellite data acquisition facilities for ISIS-1 and 2 were built up at Syowa Station in January 1976, and the VLF wideband and topside sounder data have been received on the routine basis since April 1976.

Study on the impact of sudden stratosphere warming in the upper mesosphere-lower thermosphere regions using satellite and HF radar measurements [PDF]

Atmospheric Chemistry and Physics, 2010
The occurrence of a sudden stratospheric warming (SSW) excites disturbances in the mesosphere-lower thermospheric (MLT) wind and temperature. Here, we have examined the high frequency (HF) radar wind data from the South African National Antarctic ...
