<br />. <br /> <br />crystals are carried aloft to levels where they become <br />effective as nuclei for the formation of tiny ice crys- <br />tals, which initiate a process of increasing precipita- <br />tion, <br /> <br />Cpcrations are directed and controlled by staff meteor- <br />ologists in the Palm Springs office, where surface and <br />upper air conditions arc being monitored continuously. <br />Based upon a number of wcather factors (e.g., the large <br /> <br />scale weather pattern affecting the united States, the <br />degree of airmass instability, the windflow, speed and <br />direction at various levels between the ground and the <br />effective level for silver iodide) the controllers deter- <br />mine the appropriate generators to be operated and for <br /> <br />what period of time during operable situations. <br /> <br />The in- <br /> <br />structions are telephoned directly to the individual <br />generator operators. <br /> <br />Following is a summary of the days on which operations <br />were conducted during each month, and the total number <br />of generator hours of operation: <br /> <br /> NO.
