92 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.

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
