<br />
<br />A two,.dimensional time-dependent cloud model has been used to simulate both the silver iodide and dry
<br />ice see.ding at cloud top of a rapidly developing convective North Dakota cloud. The two seeding
<br />methods produce similar results and both methods are effective in reducing the surface hail
<br />accumulations, as well as rainfall accumulations at later times. The seeding results in the earlier
<br />generation and fallout of the hail field. The melting hail is the major source of rain.
<br />
<br />The model contains bulk water microphysics and a new process is added which involves the conversion
<br />of rimed snow into graupeIlhail. The inclusion of this riming process reduces the differences between
<br />the natural and seeded simulations. The development of large snow and hail fields in the natural
<br />simulation is reduced in the riming process. The evolution of the hail field in the natural simulation
<br />approaches that of the seeded cases. The accumulated hail and rain at the surface are again reduced by
<br />both seeding methods, but by a smaller amount because the rain and hail which reach the surface in the
<br />natural simulation are reduced by the inclusion of the riming process.

<br />Experimental data on ice crystal growth measured during recent investigations in a supercooled cloud
<br />tunnel that suspended ice crystals for time periOds up to 30 min at the University of Utah have been
<br />analyzed. These experimental investigations previously generated unique data sets of mass, dimensions,
