Abstract

The correlation between seasonal mean temperatures and precipitation totals is computed at some 98 North American and European stations. Negative correlation is most frequent in summers, while negative and positive correlation appear about equally in other seasons. Normalized cospectra show that these correlation do not, in general, reflect a relationship common to a single time scale but rather one that is prevalent at all time scales.
