Researchers from the Institute of Astrophysics and Space Sciences published a study. The results of this study came from the most accurate version of the complete 3D physical model of the atmosphere of Venus, and there are various types of unstable and unexplored outer layers. View
There is an improved version of the Venus General Circulation Model (VGCM), in which a supercomputer simulates the atmosphere of Venus with the highest resolution at an altitude of 150 kilometers. These replicas allow researchers to faithfully replicate the results of recent scientific observations and reveal certain details that may help explain the many unknowns on Earth’s pseudo-gemini planets. The simulation was originally developed in France and is currently available on supercomputers in the country, but it can also be run in Portugal, the United States and Canada.
The observations are published in two articles in scientific journals IcarusIt is co-authored and led by Gabriella Gilli, the Institute of Astrophysics and Space Sciences (IA) and the Faculty of Science of the University of Lisbon. The focus of these studies is the altitude between 80 and 120 kilometers. The area is considered to be highly variable and subject to high winds from clouds and thermospheres. In addition to the VGCM simulation, the researchers also crossed the model with observations from the Venus Express probe, the European Space Agency, and telescopes on Earth to better understand the “unconscious layer”, which is used by some experts to emphasize lack of knowledge and The term of knowledge. The measured value of the area.
The works published now show unprecedented details of the simulation and show a highly variable night sky, which is confirmed by simulations. The improved version of VGCM allows for the first numerical simulation to represent various phenomena on the planet.
Thomas Navarro of the University of California, Los Angeles and McGill University, another lead author and co-author of these studies, explained that the day and night on Venus are actually fundamentally different because the planet’s rotation is very different. Slow: “A day on Venus is about 117 days long, affecting the distribution of solar radiation (…) The night is so cold that it is called the “cryosphere” above 100 kilometers. Strong temperature and pressure between day and night Gradients produce strong winds, which are faster than sound waves. This is the characteristic of these upper day-night cycles, which flow from noon to night,” the press release said.
The published results now require more observations of the planet’s outer atmospheric envelope (such as the upper middle and thermosphere). A space flight to Venus is planned for 20 years from now, but at the same time, Earth’s telescope can monitor a large number of dynamic markers (chemical compounds) and draw wind and temperature maps.
