"It turns out that many climate models have difficulties creating the correct combination tone, which is likely to impact their ability to simulate and predict El Nino events and their global impacts," he added.
Moreover, they say the latest climate model projections suggest that El Nino events will be accompanied more often by this combination tone wind pattern, which will also change the characteristics of future El Nino rainfall patterns.
Consequently, all the combination tones produced by those two generative pitches are partials of the low [E.sub.1].
With its transference of such phenomena as ring modulation, frequency modulation, combination tones, and filtering from the electronic to the acoustical domain, it presents new compositional ideas and generates new procedures like microphony and macrophony.
