Because of the destructive potential of hailstones, the                    likelihood of hail formation is an important component of                       forecasting severe weather.  While meteorologists have a good                   knowledge of the growth characteristics of hailstones, the                      factors determining whether a particular thunderstorm will                      produce hail or not are not well understood.                                         Hailstones are roundish in shape, with lobes or                            proturberances on the surface.  The cross section exhibit an                    onion-type layered structure with alternating opaque and clear                  layers caused by the presence of more or less numerous air                      bubbles.  The air bubble and crystallographic characteristics                   reflect the environmental conditions under which the hailstones                 are formed.  Some relationships between hailstone structures                    and growth environments have been found, with additional clues                  to be uncovered.                                                                     Under this grant, Dr. Pflaum will examine the air bubble                   and crystallographic properties of frozen, soaked rime grown in                 the laboratory with varied temperature and pressure.  A                         detailed knowledge of the relationship will lead to a better                    interpretation of growth environments when decoding hailstone                   structures.  The experiments will be conducted at the cloud                     physics laboratory at the University of Toronto.
