With all the wind – do you know how cold it is for your skin when you go outside?

You probably already know about the effect of wind to enhance how cold you feel. DMI’s chill factor index helps you asses just how cold it is on your skin.

As the winter weather takes more and more hold, you may be wondering just how cold it is for your skin and what to wear when you go outside.

To help you out, the Danish Meteorological Institute has a modern kuldeindeks, chill factor index, to help citizens dress more appropriately for the weather conditions when they need to spend more time outdoors.

The kuldeindeks is based on research by American and Canadian researchers who have updated the wind chill factor used previously by making simulations on people in wind tunnels and through computer based models.

The article continues below.

The index shows what temperature the air feels like at a certain temperature and wind speed.

If it is very windy and you do not move around a lot it can quickly become very cold.

DMI uses the classic Danish example of being at an outdoor football match. The temperature is 5 degrees Celsius and the wind blows at 12 m/s.

Using the index, here you put these two values into the DMI calculator, and the air temperature value will show -1.

So even if the temperature says plus five, it will feel like -1, and you may need long underwear, gloves and a hat!

The wind chill factor index works at up to + 10 degrees Celsius and with wind speeds from 1,3 m/s.

The article continues below.

Find it on DMI’s website  and calculate what the coming days of frosty weather will make the temperature feel like on your skin. Look for Beregn Kuldeindeks on their site here.
