fall and hail records which would give you added 
material to work on this theory. 
Dr. Helmut Weickmann—In connection with 
your paper I would like to recall Finley’s famous 
analysis of 600 tornadoes. He found that they 
usually developed on the right side of the path of 
a big thunderstorm complex, and this would tend 
to agree with your model, since you also have the 
main cloud formation on the right side with re- 
spect to the path. 
Mr. R. J. Donaldson, Jr.—I would like toadda 
little observational radar data to the theory. 
There is some evidence (see my paper in this vol- 
ume) which indicates that the larger the hail size 
in thunderstorms, the more the hail is displaced 
to the right of the high-intensity echo core.
