摘要：

The two-dimensional correlation analysis is applied to the study of hidden patterns in the broadband S-burst storms of jovian decametric emission. It was found that the phenomenon of S-bursts is much more complex than generally assumed. Thus, there are clear "fingerprints" of the low-altitude acceleration of the radio-sources in the standing dispersive Alfven wave. This implies that the S-burst emission, like AKR near the Earth, is generated inside depleted cavities with tenuous and hot plasma. In addition, the correlation patterns of radio storms revealed the considerable dispersion (-17.3 +/- 1.4 MHz/s at 25 MHz) of S-burst emission. These finds are new ingredients for the dominating theory of S-bursts. (C) 2012 Elsevier Inc. All rights reserved.
