Products expressed in terms of climate anomalies

- For NAEFS project

Recently, a package has been developed in NCEP to generate anomaly
forecast which based on NCEP/NCAR 40-year reanalysis data. The method
and early studye have been presented by Yuejian Zhu and Zoltan Toth
Based on latest study, the spherical harmonic/Fourier expension has been used
to fit 40-year reanalysis data. The examples of daily climatological mean,
standard deviation, time series and synoptic anomaly forecast maps for all
19 variables have been generated and posted from
one mode only (annual cycle), two modes (annual and semi-annual cycle),
three modes and four modes respectively. Please send e-mail to Yuejian.Zhu@noaa.gov
or Zoltan.Toth@noaa.gov if there is any comment/question.
