Description:"This is the third in a series of reports prepared to keep researchers throughout the meteorological community abreast of changes made to the National Meteorological Center (NMC) operational global analysis procedures. The first two such reports -- Dey, et.al., 1985 and Dey, Ballish, and Phoebus, 1987 -- covered the years 1984 and 1985-86, respectively. This one is devoted to 1987. The major change made to the global system during 1987 was the replacement of the 40-wave (rhomboidal truncation), 18-layer global prediction model with a 80-wave (triangular) version. We hope the description of this and other changes made during 1987 will prove useful to users of the NMC global analyses. Section II describes briefly the various global analyses run operationally at NMC. Section III reviews the changes we made to our operational analysis procedures during 1987. Problems are described in the final section"--Introduction.
