Al though some <br />updrafts are found on the front part of these storms, it is not <br />considered of primary importance in the formation of precipitation. <br />Normally, the important updrafts are found below cloud base a"C some <br />distance behind the precipitation area, along its trailing edge. <br /> <br />Under some atmospheric conditions multi-cell storms may become <br />very large with several new growth areas simultaneously appearing <br />on radar as distinct storm "cores" growing embedded in and around <br />the periphery of the echo area while in transition from being a <br />relatively small multi-celled severe storm into a large supercell. <br />Supercells are among the most difficult to seed to reduce hail; <br />generally supercells exhibit a characteristic "right-turnina" <br />mo~ion relative to the direction of mean steering winds. - <br /> <br />II <br />I <br /> <br />CLOUD BASE <br />SEEDING <br /> <br /> <br />~r <br />r- <br />~ <br /> <br />~ <br /> <br />30,000 FT. <br /> <br />20,QOOFT. <br /> <br />-e-!l; <br /> <br />16'20,000 Fr. <br /> <br />~) <br />,,\ <br />r'C ~r) <br /> <br />CLOUD TOP SEEDING <br /> <br />16,000 FT. <br />MSL <br /> <br />MATURE <br />STORM CELL <br /> <br />8.000 FT. <br />MSL <br /> <br />UPDRAFT AREA <br /> <br />3.QOOFT. <br />MSL <br /> <br />FIG. 2 <br /> <br />10 <br /> <br />II <br />, <br /> <br />!
