Explanations

Ratio of tidal variation of salinity to mean salinity value of the tide.

left top: value of characteristic number for a single event.
left bottom: mean value of the characteristic number within the period of data analysis.
right top: maximum value of the characteristic number within the period of data analysis.
right bottom: minimum value of the characteristic number within the period of data analysis.

Remark: The mean value is only computed at locations where all events have occurred within the period of data analysis.

Examples
