What are all kinds of strange rains?

Blood Rain 1983 65438+ 10 On 6 October, it rained blood-red for a long time in Luchun County on the south bank of the Red River in Yunnan, which made people feel surprised and uneasy.

In fact, the "blood" of "blood rain" is not biological blood, but red as blood. The reason is that a tornado appeared on the south bank of the Red River one or two days before the rain, which rolled a lot of red soil into the air and dissolved it in the rain, forming this rare "blood rain".

Of course, this is just an explanation. It remains to be verified whether the "blood rain" in the original area of the loess layer is caused by the wind rolling red soil into the sky and dissolving it in the rain.

Yu Yu According to ancient records, on March 3rd, the fifth year of Kangxi (A.D. 1666), the weather in Suide Prefecture was gloomy, and it soon began to rain heavily.

It is really "nothing to catch".

Black Rain 65438+1On the morning of March 5, 990, black rain suddenly fell in parts of Hutang District and Lu Zheng District of Wujin County, Changzhou City, Jiangsu Province, lasting for 10 minute. It is found that black rain contains many fine powders such as fibrous substances. At that time, the citizens were very surprised by the arrival of the black rain. Some people think this is a special phenomenon in celestial bodies, but others think that the appearance of black rain is an ominous sign that the weather may suddenly change. According to the analysis of Changzhou Meteorological Bureau, the reason for the formation of black rain may be that the cyclone passes through a grassland or lake, which rolls grass seeds, pollen or algae plants in the lake into the air, moves with the airflow, and then falls under the action of high-altitude airflow.
