What is the difference between strong convective rain and convective rain in high school geography?

Strong convective weather refers to disastrous weather accompanied by short-term heavy precipitation, thunderstorm and gale, tornado and hail, which can be divided into tornado, hail, thunderstorm and gale and short-term heavy precipitation. Severe convective weather disasters are disasters caused by severe convective weather.

From this definition, we can see that the cold front can bring strong convective weather, so the above statement is correct. However, it should be noted that the precipitation brought by this strong convective weather does not refer to the convective rain mentioned in our textbooks. I think the convective rain mentioned in our textbook can be regarded as the narrow convective rain, that is, the precipitation formed by the intense heating near the ground and the expansion and rise of the air. Like tornadoes.

The difference lies only in broad sense and narrow sense.
