Schuman-ludlam limit

From Glossary of Meteorology



Schuman–Ludlam limit

Critical liquid water content for growth by accretion of a hailstone or other object in a supercooled cloud such that for a given temperature and air speed all the accreted water is frozen and the surface temperature is above 0°C.

Above this limit more water is accreted than can be frozen and either is shed as liquid or is retained as spongy ice.
