<br />M'f\IJJlS ANt! DISCU::;~ION <br /> <br />Precil'-~tatiol1 ]JClLterns are by nature quite variable, not only from <br /> <br /> <br />'teason to 3",,,:,on and plClce to !Jlace, but ClI~o at a single location <br /> <br /> <br />from ~tLlrm to _ torm. Thus, an individuc11 storm can cause heavy <br /> <br /> <br />mo:i sture i,n C'nc ,-,rea, and yet produce little or no precipitation in <br /> <br /> <br />adjacent areas. An examination of the procipitation pattern for a <br /> <br /> <br />lonGer period tends to smooth out these natural single storm varia- <br /> <br /> <br />tions. Relating the actual precipitation to the historical lang- <br /> <br /> <br />term normal amounts for each given location also aids in minimizing <br /> <br /> <br />natural influences such as topography, lake effects, etc. In this <br /> <br /> <br />wrry, comparisons between contract areas and those outside become <br /> <br /> <br />more meanin&,fuI. <br /> <br />FJ,;;;:lG ::.; d,~picL~ the jJl'eclpitClVioll ctbtl'ibution in western Colorado <br />for Uk 21 JclIlUal'Y - 22 Nay period, durinG which the Grand Mesa pro- <br />ject 1:a: o:.eI'atiOlnl.
