Annular modes and apparent eddy feedbacks in the Southern Hemisphere
Lagged correlation analysis is often used to infer intraseasonal dynamical effects but is known to be affected by nonstationarity. We highlight a pronounced quasi 2 year peak in the anomalous zonal wind and eddy momentum flux convergence power spectra in the Southern Hemisphere, which is prima facie evidence for nonstationarity. We then investigate the consequences of this nonstationarity for t...
متن کاملEddy-Zonal Flow Feedback in the Southern Hemisphere
The variability of the zonal-mean zonal wind in the Southern Hemisphere is studied using EOF analysis and momentum budget diagnostics of NCEP Reanalysis data (1978-1997). The leading EOF of the zonal-mean zonal wind is well separated from the remaining EOF’s and represents the north/south movement of the mid-latitude jet. Analysis of the momentum budget shows that a positive feedback between th...
متن کاملWave Propagation in Fibre-Reinforced Transversely Isotropic Thermoelastic Media with Initial Stress at the Boundary Surface
The reflection and transmission of thermoelastic plane waves at an imperfect boundary of two dissimilar fibre-reinforced transversely isotropic thermoelastic solid half-spaces under hydrostatic initial stress has been investigated. The appropriate boundary conditions are applied at the interface to obtain the reflection and transmission coefficients of various reflected and transmitted waves wi...
متن کاملAttribution of Deep Western Boundary Current variability at 26.51N
Observed variations in the Deep Western Boundary Current (DWBC) at 26.51N, which carries the deep limb of the Atlantic Meridional Overturning Circulation (MOC), have been shown to greatly exceed in magnitude the variations of the overall basin-wide MOC, with strong variability at a range of time scales from weeks to multiple-months. Attribution of these strong DWBC variations will be crucial fo...
متن کاملEddy Current and Thermal Propagation for Quantitative NDT&E
As excitation factors of heating time and power directly affect the behaviour of eddy current and thermal propagation for eddy current pulsed thermography (ECPT), it is necessary to investigate the optimal parameters to maximize contrast between the defective and non-defective area as well as quantitative evaluation. The defect evaluation on complex geometry in the structural especially edges r...
