The Beast from the East – WindChill

BBC Weather ‘A spell of heavy snow and blizzard conditions is expected. The snow will be accompanied by very strong easterly winds leading to severe drifting. Some places could also see significant ice build up due to freezing rain from later on Thursday evening, most likely in the south of the area. Long delays and cancellations of public transport seem highly likely. Some roads are likely to become blocked by deep snow, stranding vehicles and passengers. Long interruptions to power supplies and other utilities are very likely to occur, along with damage to trees and other structures due to heavy snow or ice.’

Sub-Zero temperatures and high winds so the Chilling effects of wind needs close monitoring.

Wind Chill becomes a hazard when heat is drawn away from the skin faster than the body can replace it. This may lead to frostbite or worse.

The chilling effect of the wind, a combination of wind speed and temperature, can be represented by the lower temperature that would be required to produce the same chilling sensation for a person walking in calm conditions. Wind Chill indicates to the user how their environment really feels and is an important indicator in assessing the comfort of personnel spending periods outdoors.

Take a look at the Wind Chill Table

All Kestrel Weather Meters (except the Kestrel 1000) are thermo-anemometers and allow Wind Chill to be calculated and displayed.

The Kestrel 2000 is a small, electronic rotating vane type anemometer (wind meter) with a built-in temperature sensor. In order to quickly determine a steady temperature reading, the precision thermistor temperature sensor is mounted externally.
