Hailstone size on a reference area

Hailstone size on a reference area (i.e., Largest Expected Hail on a reference Area, or LEHA) describes the largest expected hailstone on a reference area smaller than the square kilometer considered by MESHS. LEHA is statistically derived from the hailstone size MESHS. The maximum hailstone size predicted by MESHS is expected on one or only a few LEHA reference areas within the MESHS square kilometer. However, the probability of such an occurrence is very small. On the majority of the smaller reference areas, LEHA sizes are expected.
