Lookup tables wind force

In the lookup table for wind forces, the wind force terms, used in the logbooks, is converted/translated in modern day equivalents, e.g. Beaufort and m/s. Additionally to this table in the CLIWOC database, a multilingual dictionary is available in print and in PDF format on this CD-ROM.

Description

WindForce Wind force expression, found in the CLIWOC table
CLIWOC Class Wind force according to a coarse scale (originally named KoKo-scale) where:
1 = 0-1 Beaufort
2 = 2-4 Beaufort
3 = 5-7 Beaufort
4 = > 7 Beaufort
8 = Other
9 = Missing value
Beaufort Beaufort class, cf. WMO-1100.
0: 0-0.2 m/s

1: 0.3-1.5 m/s
2: 1.6-3.3 m/s
3: 3.4-5.4 m/s
4: 5.5-7.9 m/s
5: 8.0-10.7 m/s
6: 10.8-13.8 m/s
7: 13.9-17.1 m/s
8 17.2-20.7 m/s
9: 20.8-24.4 m/s

10: 24.5-28.4 m/s
11: 28.5-32.6 m/s
12: >32.6 m/s
mps Wind speed, expressed in meters per second. Generally the midpoints of the Beaufort-classes were used. There where more information was available other values may have been used.
