Impacts of the Madden-Julian oscillation on Australian rainfall and circulation

, 2009
Impacts of the Madden¿Julian oscillation (MJO) on Australian rainfall and circulation are examined during all four seasons. The authors examine circulation anomalies and a number of different rainfall metrics, each composited contemporaneously for eight ...

From optical parametric oscillation to frequency-comb generation in whispering gallery resonators made of CdSiP2

, 2022
Paper 1167004, 6 S.Microresonator frequency combs have seen remarkable progress in the past decade. In this work, we investigate optical parametric oscillation in a mm-sized cadmium silicon phosphide (CdSiP2) whispering gallery resonator for X(2 ...

Seismology and geodesy of the sun: Low-frequency oscillations [PDF]

Proceedings of the National Academy of Sciences, 1981
The hourly averages of the solar ellipticity measured from June 13 to Sept. 17, 1966, are analyzed for indications of solar oscillations with periods in excess of 2 hr ν < 0.5 hr -1 . Nothing significant is found for frequencies ν > 0.1 hr -1 but for lower frequencies the power spectrum

Improvement of the low frequency oscillation model for Hall thrusters

, 2016
The low frequency oscillation of the discharge current in Hall thrusters is a major aspect of these devices that requires further study. While the existing model captures the ionization mechanism of the low frequency oscillation, it unfortunately fails ...

Optical-parametric-oscillation-based $\chi^{(2)}$ frequency comb in a lithium niobate microresonator

, 2021
Microresonator frequency combs based on the $\chi^{(3)}$ nonlinearity are nowadays well understood and making their way into different applications. Recently, microresonator frequency combs based on the $\chi^{(2)}$ nonlinearity are receiving increasing ...
