Each of the significant <br />precipitation maxima from the seed simulation were <br />located near regions of SL W shown in Fig. 9. These <br />SL W regions, which may have been enhanced by to- <br />pographic forcing, generated significant amounts of ar- <br />tificially produced pristine ice crystal mass that sub- <br /> <br />,- --' <br />.&<:7 <br /> <br />D <br /> <br /> <br />," 0 ~ <br />;I~~' ~ f <br />~ <br /><~ <br />~ <br /> <br />\. <br /> <br /> <br />100 105 110 115 120 125 130 135 140 <br />X (km) <br /> <br />FIG. 10.

The precipitation augmentation <br />over the middle of the domain was located downstream <br />of the initial seedline and occurred by 2000 UTe. The <br />second precipitation region in the northeast portion of <br />the domain was activated by another broad region of <br />SL W, which enhanced precipitation efficiencies due to <br />riming of the artificially produced ice particles.
