Sentences with phrase «multidecadal oscillation»
A multidecadal oscillation refers to a pattern or cycle of change that occurs over several decades. It describes a long-term fluctuation in a particular phenomenon, such as temperature or weather patterns, which repeats over a period of several decades. Full definition
