How to read weather radar chart

The color of weather radar generally ranges from blue to purple (with increasing intensity). The darker the color, the smaller the area, the greater the probability of precipitation and the stronger the intensity. In summer, areas covered by red areas are prone to short-term strong convective weather (gale, rainstorm, hail, etc.). ). Online weather usually provides radar images in recent hours. By playing the animation, we can intuitively see the changing trend of precipitation area.

Here are some examples:

1. On the weather radar map, the area surrounded by green echo usually appears due to rainfall. Generally speaking, it may rain in light green, and it will definitely rain in dark green.

2.

The radar echo changed from blue to purple, and the rainfall intensity gradually increased. Generally, the bright yellow area generally corresponds to the rainfall intensity of about 10 mm/h, and the warm red radar echo generally corresponds to the rainfall intensity of about 20 mm/h, and there may be strong convective weather such as short-term thunderstorms, strong winds and hail.
