Indications pour Baromètre
L’affichage baromètre par diagramme à barres n’est possible
que si l’instrument de mesure est en altitude égale pendant
un délai prolongé. L’instrument WINDWATCH PRO II enregist
-
re les valeurs de pression dans l’intervalle de temps sélecti-
onné par barre et les affiche sous forme de diagramme. Au
contraire de la plupart des baromètres de table, le WIND-
WATCH PRO II affiche le diagramme baromètre à intervalles
de temps pareils. Ceci permet de façon beaucoup plus précise,
d’observer le tracé d’un front météorologique.
Dans la météorologie la pression actuelle est toujours indi-
quée en se référant au niveau de la mer. Cette donnée est
appelée QNH par référence à l’aviation et elle est mesurée en
hPa. La pression moyenne sur une année à degré de latitude
moyen s’élève à 1013.25 hPa et a été déterminée en 1928 ob-
ligatoirement pour l’aviation par la ICAO. Lorsqu’on se trouve
en altitude autre que le niveau de la mer, l’instrument doit
connaître cette donnée, afin qu’il puisse calculer le QNH par
référence au niveau de la mer.
Cette donnée d’altitude est réglée dans l’affichage set-mode
baromètre. Si cette altitude est tenue à zéro, la pression de
l’air actuelle de l’altitude à laquelle on se trouve, est affichée.
Cette valeur de pression de de l’air est appelée QFE.
Instruction for Barometer
Barometer indicating with display of Bar Graph may only
be effected if the measuring instrument is at constant
height level for a longer time interval. The WINDWATCH
PRO II is recording the pressure values within the selected
time interval per bar and illustrates these as a graph. Unlike
most table top Barometers the WINDWATCH PRO II displays
the Barometer graph with equal time intervals. This detail
provides the possibility to follow the trend of a front much
more precisely.
In meteorology the present pressure is always specified in
relation to sea level. This indication is called QNH likewise
to flying activities and is measured in hPa. The average
pressure during one year over medium latitude is 1013.25
hPa and has been determined bindingly by the ICAO for the
flying sector in 1928. If one is located at a different height
than sea level, the measuring instrument must know this
height value, in order to calculate the QNH in relation to
sea level.
This height value is adjusted in the display Set-Mode
Barometer. In case this height is left at zero, the present
air pressure displayed is that at real height where one is
actually located. This air pressure is called QFE.
