Venus found the structure of the cloud



A group of researchers from Japan have found a giant structure on the top of the Venus clouds. This finding is based on Japanese observations by Japanese spacecraft, Akukaki. The findings were published in Nature's Communication January 9.

Unlike Venus, it is not like the other planets of the Solar System. The elevation of 45 to 70km between hurricane and hurricane is hiding between solid clouds. Scientists have described this noisy cave by studying the Earth's so-called "nature planet". But Japanese researchers have made progress.

These giant rows began with the Japanese spacecraft Akatsuki. Venus Climate Orbiter, a Japanese Space Research Institute (JAXA). The spacecraft has been orbit around Venus since December 2015. It was discovered by images of the Venus Planet IR2 (infrared 2) camera in images of images in the Middle and Lower Clouds. IR2's surveillance data was not of high quality, and unfortunately it did not continue to scan the structure, so it did not cause the virus to be caught.

Japanese team, Project Assistant Professor Hirocki Kashimura (Kobe University, Graduate School of Science) used the AFES-Venus computer program to calculate the atmospheric atmosphere of the Venus atmosphere. This is what is happening on the planet to predict the weather, storms, and climate change. They were expecting that Akatsuki's exposures and observations would expose the nature of the Earth's scale.

When it comes to Venus, sequences are even more important to understand what's happening in the planet. Unfortunately, the inconvenience of monitoring Venus also fails to confirm the sequence.

But the success of the AFS-Venus was already successful. This program has been successfully used to reproduce the super-rotational wind and polar temperatures of the Venus atmosphere. To create high-resolution numerical simulations of Venus, the Japanese used another simulator provided by Japan-based Ocean Science and Technology (Jamstek) Japan Institute of Oceanography.

This team analyzed the simulation and found they found what these magnetic stripe factors think. These layers are formed by interacting in two atmospheric phases. The first reason for this structure is a phenomenon that is closely related to the Earth's daily weather: Pole Jet Flow.

The Earth's atmosphere consists of mid-atmosphere, high and high-pole poles. In this study, the speculations indicate that the same thing happens to Venus. Both planets consist of large wind dynamic dynamics. But there's another way for Venus.

The mechanism for processing the structure of the Earth's scale. The giant steam generated by the Rossby waves (left) is pushed by the jet stream and the direction (right). The diameter zone in the long, cloudy zone is formed, and the structure is created, and the decline occurs. Lower clouds will be thin. Venus rotates west, and the jet stream can also be westward.

In large latitudes, in the lower latitudes, large cyclones emerge over the latitudes of about 60 degrees of latitude, due to the distribution of the Rossby wave. Venus is different from the Earth. It rotates in the opposite direction of the Earth and slowly spins: Earth's rotation is 243 days.

When Venus's lunar junction is fitted with a vortex, the torsional zone between the winds and stops and the north and south winds are a drawbridge. The flow of the planet's north-south wind, which is pushed by the transit zone, is a great downturn.

Study is a successful collection of observation and attestation. It is difficult to study the atmosphere of Venus. Many studies have focused on two models from east to west. But this study begins to add the third dimension to our understanding of planet Venus.

The group behind the study is confident of their findings, but warn that the picture is not a complete picture of the causes of massages. According to them, "Although the planetary scale layer has been discussed in the structure of the processing system as outlined above, the disturbances in our perception, unstable and angular momentum equilibrium are still unclear and will remain."

They further need to study all the details behind the phenomenon. "We need to understand these mechanisms to evaluate the strength or sensitivity of the specification processing machinery presented, but we will continue to conduct further investigations for our future studies."
