Abstract: A cold pool detection method and system is proposed. The cold pool detection method is characterized by including collecting and generating sea surface temperature data in a target area, partitioning the target area and generating partitioned areas, setting up clusters of each partitioned area, and sorting out cold pool candidate groups and detecting a cold pool. Here, the setting up of the clusters of each partitioned area is characterized by including setting clustering values for setting the clusters of each partitioned area, and setting the number of the clusters of each partitioned area. The cold pool detection method and system is capable of partitioning a target area, clustering partitioned areas to establish clusters, and using a standard deviation to determine a cold pool.
