the larger of the two cells,
The relation of the beta-concentration cross sections to position
with respect to the intensity centers of the cells, the relation between
rainfall rates and total beta concentration appears to vary, not only
with the stage of development of a storm but with the changesthat
occur while the storm is in a certain stage, in the mature stage in
particular. The profiles obtained from these few cases indicate that
the minimum beta concentration occurs with the rainfall-rate maximum
for cells that do not penetrate into the stratosphere (station 6 in the
storm of May 9 and stations 5 and 7 in the storm of May 10). The cell
that penetrated the stratosphere over station 8 in the storm of April 23
