Not all temperature conditions will lead to the same conditions

When you read the title of this article, the first question you ask yourself may be, "What does this matter?"
A good question. The first answer is, "Because it's really cool."
The second, more complete answer is, "because humans will sooner or later walk on this red planet, and it's really a good idea to imagine what we might face."
In short, the NASA Artemis project aims to build a long-term settlement on the moon by 2030. Then, it is Mars .

So, what are the weather conditions here?
The answer may surprise you. According to a new report published in the American Meteorological Society Gazette, the wind on Mars may be surprisingly mild.
"The thermometers on Mars have a great misunderstanding of the planet's condition. They make judgments based on the perception of the thicker atmosphere on Earth," Randall Osczevksi in his report "Judgement of Mars' Wind-Cold Based on Earth's Understanding."

Everything is related to the wind-cold effect. Wind-cold is a factor in air temperature and air flow rate. The National Weather Service explained, “As the wind blows through our bodies, this naturally emits and takes away our heat. With the wind speeds higher, our body heat dissipates faster and feels colder.”
According to Osczeviski, relative cold is also a factor that “the people’s body feels the medium”.
"Many people were shocked to find that water at 20°C is much colder than at 20°C. At the same temperature, water will take heat away from the body faster than air. On Earth, we do not often feel the nuances of this wind-cold effect, because the differences in atmospheric characteristics at different locations and at different days are not obvious, but not on different planets. The Earth's atmosphere, much thicker than Mars, is similar to the example of water at the upper end," he continued in the report.

You are still not tired now? great.
Based on the factors discussed above, Mars' relatively thin atmosphere cannot absorb heat as effectively as the Earth's atmosphere. If Osczevski said, "For humans, the numbers displayed on the thermometer of Mars' temperatures look colder."
How cold is it? He wrote that Osczevski said that one summer afternoon, the equatorial latitude of Mars felt like a winter day in southern England.
sounds very enjoyable! Well, in short, it makes people happy like things that transcend our planet’s boundaries.
