Norderney  together  with  intramonthly  extremes,  1971-2000  base  period  monthly  means,
and  95%-band  (climatology  ±1.96  standard  deviations).  1  kJcm" 2  is  equivalent  to  a

Fig.  3-15  Annual  runoff  of  Elbe  River  at  Neu-Darchau  weir  with  long-term  mean  (1971-2000)
and  95%-limits  (|i±  1.96c).  1  km 3 /yr  is  equivalent  to  31.7  m 3 /s.  Notable  departures  from
long-term  mean  (21.64  km 3 /yr)  recurred  at  a  frequency  of  6-8  years.  (Data:  WSA-Lauenburg.)
