Nevertheless, destructive hail occurs in the night in the thunderstorms developed out of Stratus Castellatus, and many cases may occur to the memory. A single example will suffice, which was interesting to a dweller in London or Cambridge. The hail shower which crossed the English Channel, moving towards the north-east above a northerly or north-easterly breeze, wrought some havoc on the night of August 2nd to 3rd, 1879. Cumulo-nimbus Nivosus 79. Very little need be said about the snow shower of Inversion. It is useful to distinguish it, as a minor variety, because it differs in physical characteristics and in its association with phenomena of weather from the other shower clouds of Inversion; and it is convenient to give it a symbol of its own, because the use of this saves some time and trouble to any one who keeps a record of cloud observations, or who assists in charting such observations on a cloud-map. In altitude the variety is inferior to that which has immediately preceded it in this book. Belonging properly to the winter of the higher latitudes, though common also over mountains near the equator, Cumulo-nimbus Nivosus is readily formed at no very great height above the earth's surface, and the mechanical process is completed without an ascent to the very high level of the largest hail shower. When the snow stadium is reached by a cloud of Inversion, congelation takes place not above but below the level at which the kernels of hard hail are produced. For whether the cloud is formed in the winter of high latitudes or over mountains near the equator, snow which falls locally to, or nearly to, the...
