Hamiltonian distributed chaos in the Asian Monsoon and in the ENSO

.
(May 1, 2018)

Abstract

Two subsystems of the Asian Monsoon: the Indian Summer Monsoon and the Western North Pacific Monsoon, have been analysed using their daily indices ISMI and WNPMI. It is shown that the high-frequency tails of the ISMI and WNPMI spectra have the stretched exponential form E(f)∝exp−(f/f0)β characteristic to the Hamiltonian distributed chaos with analytical values of the parameter β=3/4 and β=1/2 respectively. The relevant daily indices Niño3.4 and Niño4 (with β=1/2) of the El Niño-Southern Oscillation (ENSO) have been also discussed in this context.
