In order to solve various problems in traditional roads and extend their service life, new road materials have become a research hotspot.

A new verification approach for nowcasting based on intensity and spatial-temporal feature correction.

Forecast verification is very important in the nowcasting operation and technical development of strong convective weather. The current conventional verification method for nowcasting uses a binary classification event verification method, which exists with double punishment, leading to low scoring issues.
