How is amplitude used in the study of the cosmic microwave background radiation?

Local finite-amplitude wave activity (LWA) measures the waviness of the local flow. In this work we relate the anticyclonic part of LWA, AWA (anticyclonic ... Here,. x = displacement of wave (meter); A = amplitude; ω = angular frequency (rad/s); t = time period ... Jan 27, 2025 ... We investigate the behavior of a flexible stem completely submerged under a surface gravity wave of finite amplitude using fully resolved direct numerical ... Finite-amplitude wave activity and its governing equation will be derived, and connections with the zonal-mean flow, PV, and Kelvin's circulation will be ... Mar 16, 2025 ... In the previous section, we described periodic waves by their characteristics of wavelength, period, amplitude, and wave speed of the wave. The wave drift depends on the phase velocity relative to the Eulerian mean flow and peaks at about 1/3 of the transient Eulerian speed at geophysically relevant ... Nonstationary waves of finite (but small) amplitude propagating in a cold plasma both at an angle with respect to the magnetic field and perpendicular to ... Jun 20, 2002 ... Four large-amplitude-wave cases are selected based on exceptional large values of energy density of stratospheric fluctuations caused by the ... Jul 6, 2014 ... ... amplitude wave solutions in the long-wavelength limit. Accordingly we derive two generic coupled equations which describe the energy ... Dec 20, 2021 ... To understand audio phase, see How sound waves interact. Choose Window > Phase Meter. Right-click the Phase Meter panel ...
