Peltier A hot, muggy, afternoon or evening, with moisture laden southern winds that sap one's energy—shortly dark clouds accumulate and rear their ugly heads in the west—soon a thundercloud is in the making and the surge of the lower stratum of warm, moist air into the vortex of the cold thunderhead congeals the vapor particles—suddenly with a roar the storm descends and one of the greatest hazards to the grower is upon him, i. e. HAIL. Normally, hail is associated with thunder- storms and for the most part are localized within small and definite areas. Usually hail appears as the storm breaks and is then foUoiwed by rain. The amount of hail is correlated with the amount of rainfall, which simply means that more vapor particles are available to form hail. About Hailstones The size of hailstones varies from tiny, mushy pellets to the size of marbles and occasionally they are as large as golf balls. Their volume depends on the number of layers of ice that develop on the surface of the stones as they move downward and reascend in the upsurge of the moist air currents, before they are finally released. While hailstones are usually round, they can assume diverse shapes and become irregular, angular and at times even elongated. Duration of Storm noon. The duration of a hailstorm As hail is associated with varies from a minute or two up- thunderstorms, they occur most wards to 30 minutes. The average generally from May into Septeni- duration is somewhere between ber. They are most frequent dur- 10 and 15 minutes. Hail may fall ing July and August with some in at any time that conditions are favorable for its formation. Al- most % of the storms occur between 2 and 9 P. M., with the greatest number prevailing from 4 to 7 P. M. Less than 4% appear between the hours of 6 A. M. and May and September, and oc- casionally in April and O
