Yesterday, the fantastic sunset in Guangzhou and Foshan became a hot topic in the two cities. Many netizens shared the pictures of the pink and red sky on WeChat moments.
Why does the colorful sunset so spectacular?
According to Guangzhou Meteorological Observatory, the reason is that light is reflected by particles in the atmosphere. The radiation contains a wide spectrum of wavelengths, but our eyes are only sensitive to a part of them. Different wavelengths are associated with different colors. Red is the most visible, followed by orange. At sunset, the light takes a much longer path through the atmosphere and more oranges and reds are seen by our eyes.
The expert added that Huizhou and Dongguan on the east of Guangzhou rained yesterday afternoon. The cloud there then ran to the east to Guangzhou. The setting sun and these clouds together formed the beautiful scene. ”
