Prof To Predict Weather On Mars Texas A&M

Is there such a thing as “weather” on Mars? There are some doubts, considering the planet’s atmosphere is only 1 percent as dense as that of the Earth. Mars, however, definitely has clouds, drastically low temperatures and out-of-this-world dust storms, and Istvan Szunyogh, a Texas A&M professor of atmospheric sciences, has been awarded a NASA grant to analyze and forecast Martian weather. Mars is the most Earth-like planet we know, but it is still quite different. For example, it is much colder on Mars.
The south pole of the Earth is covered by water ice, but the south pole of Mars wears a dry ice (frozen carbon dioxide) cap. In winter, the temperature at the poles can dip to -140°C (-220 degrees Fahrenheit), which is so cold that even carbon dioxide freezes.
