What Are the Causes of Wind on Planet Mars?

Earth's magnetosphere protects it from one damaging menace in outer space: solar wind. The planet Mars, however, is not so fortunate. Without a magnetosphere, or any other kind of protective force to shield it, solar wind has been hitting Mars for years. This is just one source of wind on Mars. Scientists continue to study the other causes of wind on the Red Planet. Mars has a weak atmospheric pressure and the atmosphere is very thin, mostly made up of carbon dioxide, yet it is still able to support wind.
  1. Solar Wind

    • The core of the sun is extremely hot, and the sun does not have gravity to keep this heat from escaping. For this reason, a gust of solar heat spreads out across the universe. This solar wind causes heat wind to sweep along Mars, contributing to the erosion of the Martian surface.

    Dust Storms

    • Unlike Earth, Mars is covered with sand and dust. In fact, the dust is so pervasive it has created sand dunes throughout the planet. The same solar wind striking Mars can cause a dust storm. Though solar wind can move along planet Mars as only a hot wind, it can also whip up enough dust to create clouds of moving dust over the planet, or even dust devils. These storms can become so volatile and powerful that they add to the wind already circulating on the planet.

    Seasonal Changes

    • Just as with Earth, Mars has a spring. During the planet's spring season, the dry ice snow of the northern polar cap, made up of carbon dioxide particles, thaws, changing the temperature of that particular area. This temperature change affects the recently thawed regions of the south, and this change creates swirling winds that can also create dust storms.

    Sea Breeze

    • Mars does not have any oceans or other bodies of water, but the climate on Mars is similar to that of Earth. Just as we have sea breezes on Earth, they occur on Mars. This happens because of the science behind what creates what is known as a "sea breeze" in the first place. On Mars, the same thermal inertia that causes a sea breeze occurs because air flows from the colder region to the hotter region, and vice versa, creating a "breeze" very similar to the kind you can experience on Earth.
