How long will the sandstorm stop?

Friends in sandstorm-prone areas should know that sandstorms generally don't last long, so how long will they last? Usually sandstorms are sudden, and a sandstorm lasts for about tens of minutes. Of course, some sandstorms will last for more than two hours. Although the duration is not long, the sandstorm will still cause some damage, so everyone should pay attention to prevention together.

Dust storm weather

Sandstorms usually last about two hours.

About sandstorm warning:

1, yellow warning of sandstorm

Standard: sandstorm weather may occur within 12 hours (visibility is less than 1000m), or sandstorm weather has occurred and may occur and may continue.

2. Orange warning of sandstorm

Standard: Strong sandstorm weather may occur within 6 hours (visibility is less than 500 meters), or sandstorm weather has appeared and may appear and may continue.

3. Red warning of sandstorm

Standard: Strong sandstorm weather may occur within 6 hours (visibility is less than 50 meters), or sandstorm weather has appeared and may appear and may continue.

Ecological effect of sandstorm;

Although there are many hazards of sandstorm, the whole process of sandstorm is also an indispensable part of natural ecosystem.

For example, 1, a large amount of iron brought by red dust storms in Australia has been proved to be an important nutrient source for plankton in the Antarctic Sea. Phytoplankton can consume a large amount of carbon dioxide to mitigate the harm of greenhouse effect, so the impact of dust storms is not all negative. Perhaps on another level, sandstorms may also be a symptom of the earth's response to environmental changes, just as we cough when we have a cold to remove waste from the trachea. Many Australian climatologists gathered to study the nutrients provided by sandstorms in tasman sea and many other impacts. They found that the red seasonal sediments of Australian sandstorms can also be found in New Zealand, which enriched the land of New Zealand. Therefore, nutrient loss caused by dust storms in Australia will lead to nutrient harvesting in New Zealand.

2. According to the analysis data, the fertile soil sediments in Hawaii can also prove that many nutrients also come from distant Eurasia. Just because the two places are separated from Wan Li, it is impossible for ordinary winds to blow inland dust so far. So it is the sandstorm that brings tiny dust containing nutrients to an altitude of 3000 meters, crosses the ocean, and then spreads them, which will generally disperse them.
