Number and size-controlled rainfall regimes in the Netherlands: physical reality or statistical mirage?
Abstract. An experimental study aimed at identifying special rainfall regimes with the help of co-located disdrometers is performed. Eight potentially special events (i.e., 4 number-controlled events and 4 size-controlled events) are identified and examined. However, the cross-check with additional, independent radar measurements reveals no clear evidence of such regimes. The research underscores the difficulty in confirming seemingly straightforward questions about rainfall patterns and dynamics that have been theorized in the literature for several decades. It also questions the reliability of previous claims and serves as a reminder to approach such problems with more caution, emphasizing the need for rigorous uncertainty analysis and multiple cross-checks between sensors to avoid misinterpretation.
