On the eve of typhoon "Haibeisi" landing in Japan, pink and purple skies appeared in many places. Why?
The symptoms before typhoon Haibeisi come are just like many unusual phenomena before a major earthquake. The pink-purple sky appeared in many places, which was affected by the typhoon.
The strong typhoon "Haibeisi" is expected to land in Japan in the evening of the 12th, which will bring violent storms to Tokyo and neighboring counties and cities. Affected by this, Tokyo Disneyland in Japan issued a notice saying that the park will be closed all day on the 12th, and it will be closed until noon on the 13th, and then the operation hours will be adjusted as appropriate. It is reported that this is also the first time that Tokyo Disneyland has closed due to typhoon.
The Japan Meteorological Agency has hoisted the highest level warning of heavy rain and flood. Affected by this, on the 12th, the Shinkansen and Tokyo Metropolitan Railway were shut down, and more than a thousand flights were grounded. Rugby World Cup and Formula One (F1) racing also announced the cancellation of the day's activities. The Japanese Embassy in China appealed to Japanese tourists and Japanese citizens planning to travel to pay attention to safety.
Super typhoon "Haibeisi" may bring the biggest storm in 6 years. The local government has advised more than 1 million residents to evacuate urgently for fear of floods and other disasters. At present, one person has died due to strong winds.
The color of the sky (that is, the color of the atmosphere) is actually the composite color around the blue in the spectrum, which we call "blue". If there is no atmosphere, the sun we see is a very dazzling fireball in the dark space background, and the astronauts in the space station can see this scene, because sunlight loses most of the blue areas in the spectrum through the atmosphere, and we often see the sun through the atmosphere as yellow. When blue light is mixed with yellow light, it is white.
When a typhoon or a lot of rain clouds are coming, there will be a lot of water vapor and smiling dust particles in the air, which will reduce the transparency in the air, and this will absorb or reflect the light with weak penetration in the air, leaving only the red (or pink) with the strongest penetration. When the colors such as pink and red are intertwined with the color of night, a purple sky will appear.
However, the purple sky doesn't necessarily exist before a typhoon or rain. I have tried to see the purple sky when it was sunny for a week before and after, but the purple range is very small, accounting for only about 1% of the sky.
