Beaufort Windscale Chart

$0.00

Description

Beaufort wind speed chart, with comparative AS4055 wind speeds and speed conversion tables from m/s to km/h. Most weather reports, and news reports give wind speeds in km/h whilst the wind loading code uses m/s. Most annual storm damage occurs at 90 to 110 km/h how does that relate to the AS1170.2 regional wind speed of 45m/s? Whilst dust and paper will be picked up at around 20km/h, how does this relate to an industrial building being closed, or to site works continuing?
