Sentences with phrase «year periodicity occurs»

Not exact matches

A period of very weak signal strength (with a near 5 - year periodicity) occurs in much of the intervening epoch.

While their periodicity can be quite irregular, El Niño and La Niña occurs every 3 - 5 years on average.

For example, about 800,000 years ago a shift of the dominant periodicity from a 41,000 yr to 100,000 yr signal in glacial oscillations occurred (called the Mid-Pleistocene Transition, see e.g., Clark et al., 2006), and while a lot of ideas exist for why this should be the case, there's no bulletproof answer to this.
