Through the dynamical coupling between ocean and atmosphere, the vertical advection of anomalous subsurface temperature by the mean upwelling and the zonal advection of mean sea surface temperature (SST) by anomalous current constitute the so-called the thermocline and zonal advective feedbacks that are essential for El Nifio / Southern Oscillation (ENSO) coupled dynamics. In this paper, we dem...

The fundamental equations are linearized by the method of small perturbations for the conditions of hydrostatic equilibrium and geostrophic balance of meridional forces. I n a first case, Fickian momentum diffusion is used; in a second case, a shearand latitude-dependent eddy viscosity is used. A wave solution for the zonal wind oscillation, having in meridional profile the shape of a probabili...

All-sky maps of the cosmic microwave background temperature fluctuations are usually represented by a spherical harmonic decomposition involving modes labelled by their degree l and order m (where −l 6 m 6 +l). The zonal modes (i.e those with m = 0) are of particular interest because they vary only with galactic latitude; any anomalous behaviour in them might therefore be an indication of erron...

[1] On the basis of Colorado State University (CSU) Na lidar observations over full diurnal cycles from May 2002 to April 2006, a harmonic analysis was performed to extract semidiurnal perturbations in mesopause region temperature and zonal and meridional winds over Fort Collins, Colorado (40.6 N, 105.1 W). The observed monthly results are in good agreement with MF radar tidal climatology for U...

Perturbation theory in quantum mechanics studies how quantum systems interact with their environmental perturbations. Harmonic perturbation is a rare special case of time-dependent perturbations in which exact analysis exists. Some important technology advances, such as masers, lasers, nuclear magnetic resonance, etc., originated from it. Here we add quantum computation to this list with a theo...
