Wind
speed; given in tenths of a meter per second. From the descriptive terms
of wind force given in the observations, a first division into “Beaufort”
classes resulted in the m/s given here. Most of the values are the
midpoints of each Beaufort class, cf. WMO-1100. In those cases that more
information was available, other values may have been used. Bft 0: 0-0.2
m/s Bft 4: 5.5-7.9 m/s |
