I believe that most people will think that it will rain frequently in coastal areas, especially the residents of coastal areas in our country, they will believe it, because they live in coastal areas. Maybe they would say that our country is often affected by typhoons in summer and autumn, and it rains every minute.
But there is always a special area in the world. The Atacama Desert is a desert on the west coast of South America. The main part is in the territory of Chile , and some are located in Peru, Bolivia and Argentina.
Atacama Desert, under the combined influence of the subtropical high pressure zone sinking air currents, offshore winds and the Peruvian cold current, this area has become one of the driest areas in the world and is known as For the "dry pole" of the world.
In this dry area, the average annual precipitation is less than 1mm, and the usual daytime temperature is around 40 degrees Celsius. Even the cactus is difficult to grow. Scientists have verified that this desert did not rain during the four hundred years from 1570 to 1971. It can be seen that even if it is very close to the ocean, it is not always rainy!
is even more shocking. Although this is " dry pole ", there is no shortage of "water" here, but it is presented in front of people in the form of fog.
When the Atacama region was hit by a severe drought in 1956, a retired professor in Chile took inspiration from the way plants in the area live and invented a method of catching fog with a net.
When the "Carmen Choga" fog passes through this large net, the damp water vapor in the fog condenses into water droplets in the fine mesh, and the accumulated water flows to the sink and water pipe under the large net In a storage bucket. The water collected in this way is very clean,It can be drunk directly or used as agricultural irrigation.
This really confirms the old saying-"Knowledge is wealth".
