Table 9 Thresholds of storm cell merge

From: Thunderstorm identification algorithm research based on simulated airborne weather radar reflectivity data

ThresholdMeaningDefault value
Elevation merge(°)The maximum difference in the elevation angles between the top of one storm cell and the bottom of another storm cell required to merge the storm cells3
Horizontal merge(km)The maximum horizontal distance between two centroids required to merge the storm cells8
Height merge(km)The maximum difference in the height between the top of one storm cell and the bottom of another storm cell required to merge the storm cells4
