Show Lightning Still A Big Mystery But Science Advises Cooperating With It PITTSBURGH, PA. There is no use getting all charged up about lightning. "Lightning Is something you have to co-operate with," A. J. Fink, a Westinghouse expert on the subject, explained. "You can't fight it." There are no real experts on lightning. Though everyone has seen lightning, few folks seem to know how - the "bolts from the blue" are born. Scientists themselves them-selves aren't .too positive; Henry Rockwood, Pittsburgh's weatherman, explained that lightning light-ning occurs mainly during summer months because the earth soaks up more of the sun's heat. A vertical column of moist air starts moving upward when it is heated by the earth. As it reaches the "dew point," or condensation point, the air is saturated with moisture and that's how clouds are formed. But if the moist air column is deep enough and high enough, that old bogey of the airmen, a thunder-head, thunder-head, is formed. Through a mysterious mechanism mechan-ism in the movement of ic crystal crys-tal sand droplets, a separation of electrical charges occurs. |
