Geography.of.positive,.negative,.and.insigniicant.correlation.between.the.four.
climate. indices. and. precipitation,. using. the. gridded. precipitation. data.. See. Figure. 10.1. for.
locations.of.LTER.sites.
for.determining.this.classiication.and,.if.more.than.one.input.is.signiicant,.ranks.
them.in.order.of.importance.
For. the. LTER. station. data,. a. similar. procedure. was. used,. but. with. station. values.
instead. of. gridded. values.. Monthly. values. for. precipitation. (converted. to. anomalies.
using.the.mean.and.standard.deviation.for.each.station).at.each.station.were.correlated.to.
the.same.index.values.that.were.used.for.the.gridded.data.(Table 9.2)..These.correlation.
values.were.then.subjected.to.MBPA..A.summary.of.the.results.are.given.in.Table 9.3.
