The association patterns shown in Fig. 2 case 4 are used as an example to plot the triple-layer mosaics and give their detailed meanings. Taking the SSTA as an antecedent, the specified lattice point has only one pattern, (6%, 100%), which means that when the SST anomaly increases abnormally, the CHL anomaly will have dropped abnormally at three time intervals earlier, and that the two events occur with a support of 6.0% and the former occurrence promotes the latter to occur with a probability of 100%. In the parameter mosaics, there is only one column to represent the parameter, CHLA, and the mosaic corresponding to is shaded to represent its severe negative change. The color and length of the evaluation mosaic are plotted with the linear function using the support and confidence values (6 and 100%, respectively). For the time mosaic, the value 3 indicates that the CHLA leads the SSTA by 3 time intervals, and the third mosaic to the right of the middle is shaded. The pattern is plotted in Fig. 4(a). Using SLAA as an antecedent, the plot mosaics are the same as with SSTA, and the pattern of (12%,100%) is shown in Fig. 4(b): when the anomaly of SLA drops slightly, the anomaly of CHL will increase abnormally after two time intervals, with a support of 12.0%; the former occurrence promotes the latter to occur with a probability of 100%. There are four patterns with ENSO as an antecedent, and the strategy used to construct the evaluation mosaics groups the three patterns, (4%, 85%), (5%, 85%), and (3%, 100%), into one combined triple-layer mosaic, plotted in Fig. 4(d) from left to right, respectively. The pattern (4%, 100%) is represented by one separate triple-layer mosaic [Fig. 4(c)].
