Sea Level Fluctuations in Tórshavn, Preliminary Results
TABLE IV Harmonic constants for Torshavn. The Greenwich Phase lag is the
lag of the constituent relative to the phase of the relevant component of
the astronomic đriving force measured at Greenwich. The local time lag is
the time that the constituent lags behind (in case of minus : leads) the
driving force. Amplitude and phaselag have been corrected for nodular mo-
dulation.(ADD.LAG : Additional lag, GR.P.LAG : Greenwich Phase Lag,
L. T. LAG : Lo c: a 1 Ti. me Lag)

TALVA IV. Aldingar í flóðini í Havn. Fyrstu trý røðini vísa almenn
nøvn og eyðkenni, fjórða rað: Títtleikan (aldingar í tíman), fimta rað:
Aldutíðina (í tímum), sætta rað: Styrkina (í cm), sjeynda rað: Seinkingina
av aldingini í mun til sól og mána roknað í gradum og frá Greenwich og
áttanda rað vísir seinkingina roknaða í tímum frá Havnini (— svarar til
at aldingin er komin framum).
Meteorological influence Having determined — to a certain
degree — the astronomic tide, this may be subtracted from the
original time series. Referring to the resulting series as »Reduced
water level« we may investigate to what degree this series is
of meteorological origin.
In fig. 6 is shown the PDS of reduced water level and in
