Meteor smoke’ be able to spawn in the map and clouds on Mars

A computer simulation shows the mid-height of the clouds on the Planet.

“Cotton candy” clouds in the middle atmosphere of Mars may be due to die from meteors.

A new study suggests that the atmospheric destruction of the enemy, makes small particles of a substance, which may be the seed of your thin clouds. The discovery may help solve the mystery of how the clouds are growing in the middle of the atmosphere, the improvement of the scholars in the understanding of the Mars climate now and in the past.

“The clouds do not just form on their own,” Victoria Hartwick, a graduate student at the University of Colorado in Boulder and lead author of the paper, said in a statement. “They need something that they will be able to condense on it.”

On the Earth, the water molecules will stick to the small grains of sea salt or dust in the air is blown in until the white threads of which can be seen from the ground and the clouds. But Mars is missing, the sea, the salt, and the scientists have not been able to explain the presence of the midatmospheric the clouds, through the study of matter on the Red Planet.

Nevertheless, both Mars and the Earth in a cloud of seed in common. Previous studies have shown that the substance has been destroyed, meteors, known as the meteoritic smoke, and can assist in the build-up of clouds in the near vicinity of the Earth’s poles. Hartwick and her colleagues examined meteoritic smoke, you can also see the clouds that are floating in the middle atmosphere of Mars, among the other well-known types of clouds.

“Our model is not able to form clouds at these altitudes before, we meteorite impacts],” Hartwick said. “But right now, they are all there, and they seem to be in the right place.”

The study is published today (17 June) in the journal Nature Geoscience.

To catch a glimpse of the old Mars

Scientists have already cracked the secret to a Martian, and cloud type. Forty miles (65 km) above the Red Planet’s surface, and clouds of carbon dioxide ice are floating by in the atmosphere. These clouds form when a mineral substance is carried away from the surface, allowing water molecules to attach to the material and grow to the clouds.

However, the circulation models have difficulty to explain how the thinning clouds, which is 18 to 37 miles (30 to 60 miles above the surface, in the middle of the night. This is a thin, candy-like clouds are smaller than that of most of the Earth’s clouds, but they can have a dramatic effect on the climate on Mars.

Each and every day, from 2 to 3 tons of rocks, and most of them are relatively small, and a crash into the Martian atmosphere. It is heated in passage through the atmosphere, the tears, these meteorites are from each other, they breathe a considerable quantity of the dust in the air.

In order to determine whether or not the meteors burn up in the atmosphere, it may be used as a basis for the space of clouds, Hartwick, and her colleagues combined data from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) satellite containing a huge computer simulations, and that caused the flow, and the turbulence of the atmosphere of the planet. The researchers found that, including those of the meteoritic smoke in the simulations of clouds and the conditions are similar to those seen on the Red Planet.

The new simulations also showed that, for thin clouds, it can lead to significant variations in temperature of as much as 18 degrees Fahrenheit (10 degrees Celsius). When a pole is reached, the temperature change of the temperature and the pressure increase of the amount of meteoritic smoke, which, in turn, pushes the low clouds is higher than in the simulation without the micrometeoroids. The small, meteor-built in the clouds on the middle atmosphere and the strengthening of thetwice-daily changes in temperature in the middle atmosphere, as well as the large-scale atmospheric circulation, the authors wrote.

The discovery may help reveal information not only about the weather conditions on the day of the march, but also the planet’s past climate. The old Mars was a warmer and wetter world, which is by the water on the surface. How the planet lost its water, will remain a mystery for now.

“More and more, climate models find that the ancient climate of Mars, when the rivers flowed over its surface, and the light would have been determined, has been through high-altitude clouds,” study co-author Brian Toon, a study of clouds on the Earth and beyond at the University of Colorado in Boulder, said in the same statement. “It is likely that this finding is an important part of the idea that the warming of the Planet.”
