Scientists have told how the rains have changed Mars

Scientists from the Smithsonian Institution and Johns Hopkins University created a model of Mars with the atmosphere and came to the conclusion that before it was full rains. In addition, they are sure that in the distant past, Mars had something in common with the Earth atmosphere.
Scientists have told how the rains have changed Mars However, the researchers, Dr. Robert Craddock and Dr. Ralph Lorenz, recall that initially atmospheric pressure here was much higher than the Earth – about four times. And this influenced how much water droplets hit the surface of the planet and how large they were. When Mars was very young, the drops were tiny, no more than 3 mm, the rain was more like a fog. Then, as the atmospheric pressure fell, the drops became larger and bigger, the rains went stronger. As a result, it came to the point that drops of 7.3 mm or more diameter left small craters on the surface of the planet. Subsequently, the water created real valleys. When the atmospheric pressure on Mars fell below the ground, then on the surface literally swept the real grandiose hurricanes. " Many people analyze the rain on Earth, but few have tried to use these theories to understand the atmosphere of early Mars ," says Robert Craddock.
