Mars is seen as the best choice for humans to move into space. What is the weather like on Mars?

The atmosphere of Mars is mainly carbon dioxide and is frequently impacted by strong dust storms. Its temperature is often so low that it can freeze the blood. Mars rarely has the windy and sunny scenes that are common on Earth. It is often attacked by sandstorms. Dust may even spiral up to several kilometers high. Bad weather conditions will endanger the landing of spacecraft on the surface of Mars. Therefore, Knowing the weather conditions on Mars in advance is particularly important for completing the Mars exploration mission. To this end, scientists from the bureau invented this Mars weather forecast system based on the principles of atmospheric circulation and weather forecast systems on Earth. Water in the Earth's atmosphere is the main factor causing changes in the Earth's weather, while dust in the Martian atmosphere plays the most critical role in controlling the Martian weather. In addition, because the Martian atmosphere is thin and there is no water to store heat like Earth's oceans, temperature changes on Mars are more likely to become extreme. At the same time, air flows such as rising hot air and sinking cold air on the Earth will produce winds. Similar situations occur on Mars, but they ultimately manifest as sand and dust movement on Mars.

Mars is regarded as the planet most similar to the Earth. Like the Earth, Mars has obvious seasonal changes. The length of a day and night is 24 hours, 37 minutes and 22.6 seconds. The revolution time is slightly longer than that of the Earth. A Martian year is almost two years on the Earth. However, many Mars researchers believe that Mars once experienced a time when life was as prosperous as Earth, but later became desolate due to changes in the environment.

On Mars, 95% of the gas is carbon dioxide. Carbon dioxide warms the Earth, but it doesn't warm Mars. Because the atmosphere on Mars is thin, with a density less than 1% of the Earth's atmosphere, there is no way to preserve heat. Therefore, the surface temperature on 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 freezes at such low temperatures. Dry ice forms thick ice caps at the poles of Mars, just like the icebergs at the North and South Poles on Earth. These natural conditions constitute a unique climate environment on Mars. Compared with Earth, the conditions on Mars, although harsh, appear stable. Thin clouds and low temperatures that remain constant all year round often make people feel that there is nothing particularly noteworthy about the weather on Mars. But in fact, Mars also has its moments of sudden changes. Janyok said that there are huge dust storms on Mars. These dust storms will erupt every 2-4 Martian years. When they erupt, dust rises from the surface of Mars, covering the entire Mars in an instant, and then disappears for several months. will disperse.

So there is no way for humans to survive on Mars.
