How to read weather radar charts

The color of weather radar generally ranges from blue to purple (increasing intensity). The darker the color and the smaller the area, the greater the probability of precipitation and the stronger the intensity. In summer, the area covered by the red area , it is extremely prone to short-term strong convective weather (strong winds, heavy rain, hail, etc.). Weather websites generally provide radar charts for the past few hours. By playing animations, you can intuitively see the changing trends of precipitation areas.

Here are some examples:

1. On the weather radar map, the area surrounded by green echoes generally corresponds to rainfall. Generally speaking, light green is likely to have rainfall, and dark green is certain to have rainfall.

2.

The radar echo changes from blue to purple, and the rainfall intensity gradually increases.

Generally speaking, the bright yellow area generally corresponds to a rainfall intensity of about 10 mm/hour, and the warm red radar echo generally corresponds to a rainfall intensity of about 20 mm/hour, and there may be short-term thunderstorms, strong winds, hail and other strong convective weather
