Will lead to heavy rainstorm, even extremely heavy rainstorm
When the strong rainfall echoes in a north-south direction move northward
The area it passes through will suffer from the train effect
The continuous rainfall is difficult to stop
If the strong north-south rainfall echoes move eastward
Then no train effect will be formed
Heavy rainfall passed by in bursts
However, today's strong echo is in the shape of a "river"
Even if it moves east/west
Not forming a train effect, it is also a wave effect
