Yesterday evening, the urban area of ​​Zhengzhou struck, and it was dark, and the electric flashes were thunderous. Because it happened in the evening, there was sufficient flow energy, abundant water vapor conditions, the sun was not falling, and the sunset westward, so there were rare heavenly phenomena that were intertwined with green sky, rainbow hanging sky, burning clouds, and Benlei lightning.

The first is the green sky. At 18:00 yesterday, over the urban area of ​​Zhengzhou, it was covered by a strong dark cloud from north to south, and it was dark quickly. At this time, the "Sanfu Sky" is often the time when the sun is not falling and the sunset is born.

Subsequently, the sky changed, showing a green tone. The green sky is really rare. During the storm of yesterday, the light of the light was green. What is the reason?

The reason is that the droplets and ice grains in the storm are extremely density, which is almost connected. Blu -ray and some green light. Due to the short light waves, the penetration force is poor, and it is prone to scattering. The blue of water drops and ice drops, the yellow of the sunset is superimposed, the sky looks green. In other words, this is a rare complex optical response to the sunset in the sunset.

At 19:10, although the urban area of ​​Zhengzhou was still dim, the clouds in the west had become thinner, and the sun was falling into the horizon to shoot golden beams. At the same time, the rainbow spanned the city of Zhengzhou and instantly captured the hearts of the general public.

The rainbow spanned, and the background was a strong black cloud. Sometimes the lightning passed through the Hongqiao, and the thunder was very rare. And the bottom of the rainbow, there is a white cloud. In fact, the rainbow is not the same. The rainbow in Zhengzhou city yesterday was also a double rainbow, but the outer rainbow was more dim.

So, during the heavy rain during yesterday, why would there be a rainbow? This is because the rainbow is an optical phenomenon in the weather. When the sun shines into the water droplets in the air, after being refracted and reflected, the arched colorful spectrum is formed on the sky. , Yellow, green, blue, 绿, purple color.

This means that the emergence of rainbow requires the cooperation of sunlight and water droplets. At 19:10 yesterday, the sun was landing, and the sun shot obliquely. In addition, a large amount of water vapor over Zhengzhou City created a suitable environment and excellent conditions for the emergence of the rainbow.

The rainbow darkened and the sunset became red. Whether it is when the rainbow appears or the setting of the setting sun, there are lightning lightning, and many people have taken the rare picture of lightning with the rainbow and Caixia.

This is because, although the heavy rain weakens, the strong pairing weather continues. Yesterday in Zhengzhou's heavy rain process, there was abundant water vapor conditions and sufficient stream energy, which caused the occurrence of extreme weather. The emergence of lightning and rainbow is also the embodiment of the strong weather in summer. The urban area of ​​Zhengzhou is very large, but the local area is the first to become thinner, revealing the sunset, and the wonders of various natural phenomena are created.
