<DIV><FONT face=Arial size=2>I'm a weather forecaster working for Tuscany
Region, Italy. We use WRF-NMM as an operational model and MET to verify its
results. In the MET user guide, appendix C, the Spearman rank correlation is
indicated as 6/n(n2-1)*... instead of 1-6/n(n2-1)*..., as indicated in many
articles (Schultz, 1995, An explicit cloud physics parameterization for
operational numerical weather prediction, Mon. Wea. Rev., 123,
3331-3343).</FONT></DIV>
<DIV><FONT face=Arial size=2>I would like what is the method used in MET to
calculate this index, in order to interpret statistical results in a
reasonable way.</FONT></DIV>

<DIV><FONT face=Arial size=2>Thanks in advance.</FONT></DIV>
