"What's the weather like on Mars" caused a heated discussion. What do you think it will be like?

People have always thought that Mars is the most similar planet to the Earth. Just like the earth, there are four distinct seasons on Mars, 24 hours, 37 minutes and 22.6 seconds, and the revolution time is slightly longer than that on the earth. A Mars year is equivalent to two years on Earth. However, many Mars researchers believe that Mars once experienced the same prosperous years as the Earth, but later became desolate due to environmental changes.

On Mars, 95% of the gas is carbon dioxide. Carbon dioxide warms the earth, but it won't warm Mars. Because the atmosphere on Mars is very thin and the density is less than 1% of the earth's atmosphere, there is no way to keep warm. Therefore, the surface temperature of Mars is very low, rarely exceeding 0 degrees Celsius; In winter, the surface temperature of Mars can even reach-140 degrees Celsius.

At the poles of Mars, even carbon dioxide will freeze at such a low temperature. Dry ice forms thick ice sheets at the poles of Mars, just like icebergs at the north and south poles of the earth. These natural conditions constitute the unique climate environment on Mars. Compared with the earth, the conditions on Mars are harsh but stable. Thin clouds and persistent low temperatures often make people feel that the weather on Mars is nothing special. But in fact, there are times when things change suddenly on Mars. Zhan York said that there are huge sandstorms on Mars, which erupt every 2-4 years. When they erupt, dust rises from the surface of Mars, covering the whole of Mars for a period of time, and then it will not disperse for several months.

In addition to temperature changes, these storms are also what we need to master and predict. ? Zhan York said. Together with his team, he will closely monitor and analyze the data related to Mars weather, and provide the results directly to the relevant departments of NASA's Mars research. ? The most direct benefit of Mars weather forecast is that it can effectively increase the landing safety factor of the exploration robot when landing on Mars. Mark? Lemmon said that he is still in Texas A & amp； M University, he personally led or participated in many Mars development projects. ? In the long run, in the future, when astronauts begin to explore on Mars, the work of weather forecasting will become more important.

However, how to determine the daily rain and snow on Mars, according to Jan York? All forecasts must be based on solid and reliable data. ? In order to predict the weather on Mars, new york must collect various physical parameters on Mars, such as temperature, wind, wind direction and barometric pressure data, and establish a meteorological digital model. In fact, the weather forecast on TV is based on a similar meteorological model. According to this model, meteorological scientists can predict the weather change, or the weather change trend over a period of time. However, establishing a detailed model of Mars weather parameters may be a more valuable part of the Mars weather forecast plan. ? We hope to record the data between the atmospheres of Mars as detailed as possible, which is the main purpose of our project. ? Zhan York said.
