<br />styrofoam containers extending its in-flight seeding capability. <br />The aircraft seeds at temperatures of -lOC to -12C---usually about <br />an altitude of 20,000 feet in summers---penetrating either the tops <br />of newly growing clouds near the parent storms or new storm growth <br />on multi-celled lines as shown in Figure 4 (page 10). <br /> <br />The design of the WKWM cloud seeding operations is similar to <br />others of its kind: The meteorologist makes the initial decision to <br />launch and position the seeding aircraft. Once the pilot arrives <br />at the storm, the meteorologist and pilot confer on what the pilot <br />finds and what is known from radar and/or visually; the seeding <br />decision is made by the meteorologist. UnleSs planes run into <br />emergencies, run out of seeding agent or become low on-fuel, flight <br />termination decisions are made by the meteorologist. WKWM pilots <br />are highly trained and have had intern experience for at least a <br />year before being allowed to fly as pilot-!n-oommand working in the <br />updraft areas near precipitation cores of severe thunderstorms. <br /> <br />communications and teamwork are a necessity if the program is <br />to operate effectively and be successful. The 1994 team-of pilots, <br />pilot interns and meteorologists was another such mission-oriented <br />group and worked well together. Two of our 1994 pilots-in-command <br />had been interns on this program for three years and one had been <br />au intern for two years. <br /> <br />19 <br />
