- small hail
- Definição1
- Precipitation of translucent ice particles, which falls from a cloud. These particles are almost spherical and sometimes have conical tips. Their diameter may attain and even exceed 5 mm. Usually, small hail is not easily crushable and when it falls on a hard surface it bounces with an audible sound on impact. Small hail always occurs in showers. For coding purposes, small hail must be classified as either slight, moderate, or heavy. The intensity is determined by using the accumulation rate as given for hail.
