This study examines the slow modulation of El Niñ o–Southern Oscillation (ENSO) intensity and its underlying mechanism. A 10–15-yr ENSO intensity modulation cycle is identified from historical and paleo-climate data by calculating the envelope function of boreal winter Niñ o-3.4 and Niñ o-3 sea surface temperature (SST) indices. Composite analyses reveal(More)
We examine the influence of the South-Amer-ican land-mass and its mountains on the significant cyclic diurnal and semidiurnal components of the average circulation in the adjacent area of the southeastern tropical Pacific (SEP). Our approach is based on a number of numerical simulations with the regional atmospheric model weather research and forecasting(More)
Low-Ag solder SnAgCu (SAC) is more suitable for improving the shock performance of solder joints as reported by many papers. However the properties of low-Ag solder, with different Cu contents, under service conditions are lacking. The forming mechanism of the intermetallic compound (IMC) and the relation with the joint strength need to be investigated. In(More)
In this study, we examine marine low cloud cover variability in the Southeast Pacific and its association with lower-tropospheric stability (LTS) across a spectrum of timescales. On both daily and interannual timescales, LTS and low cloud amount are very well correlated in austral summer (DJF). Meanwhile in winter (JJA), when ambient LTS increases, the(More)
