<br />CHAPTER IV. A~iOSF.qER:C - METEOROLOGICAL SIJJIES <br /> <br />A rese~r~h and expericrent~l progra~ tc obje~tively manage ?re- <br />cipitation augment~tion must in~lude an an~iysis or the types and ~lass€a <br /> <br />I <br /> <br />of historical stor~ syste~s, E~p~tSl ~rFn~'tion m~del~_qus~be <br />developed for ~~~i~b~l~~ty ~nd accuracy. Tne information presented ~n <br />~_----""''''__~ ~__::'E.-~______~--"'--=~",""_=----~~"'!';:~"," <br /> <br />this re?ort is a preliminary step in the preparation of a prediction <br />~odel for the Jemez ~ount~in Proje=t, Cl~ssifications, observatjons~ <br />measurements and field stildies accomplished during the FY 1968 are also <br />incbded. <br />The meteorological dis~ussions have been arranged according to the <br />types of weather data av~ilable, their special ~ethods of analysis and <br />their specific ap?licati~n to the Jenez Mount~ir. Prcje=t. <br />A. Synoptic Classification of Store Systems <br />Surface weather maps with three ho~r intervals were obtained fro= <br />the ~fuite Sands Missile Range, Forecast Branch: and 300-nillibar (mb) <br />maps with 24-hour intervals were obtained fro~ the ~eather Bureau's <br />"Daily ~'!eather ~Ia?" for '..Lse in this classification of storm systems. <br />Weather and storms can be classified by using any measurable :;>ara- <br />meter, atmospheric or othe~~ise5 which has some relationship with the <br />weather. for exa~ple, in the Jemez area, the most basi~ classification <br />is bet~.]t:en "sti."!lIIler" storms arrd "~dnter" storms. The former is char- <br /> <br />acterized by diurnal frequency of occurrence and isolated cell activity, <br />the latter is characterized by mesoscale patterns of air mass action and <br />interaction. It is with this latter, and more difficult type of storm, <br />that the Jeme~ Mountain project research has been involved. <br />A conputer model of isolated cell storms can be reduced to one <br />dimension. 1 Mesoscale stor~ models are not so well developed, and ~ay <br />ultimately be restricted to two or nore dimensions, Two different ty?es <br />of t~.,o-di::lensional displays are included~ 1) the "plain" vie~,rs as dis- <br /> <br />l~'Jeinstein, A. 1. and Davis, L.
