How do they measure wind chill factor?

It doesn't feel like the temperature is any lower,
it feels like temperature is what temperature is and the wind is blowing..
It's even worse when in the news they seamlessly mix or jump back and forth between the real temperature and wind chill.jim hardy said:I hate that "Wind Chill" hype.

DrClaude said:And even worse than the wind chill is the humidity factor.
I think of wind chill as how quickly heat is removed from an object, the object can be ether a person or a bowl of water.zuz said:Please correct me if I'm wrong, but I thought wind chill is a measurement of how cold it feels. A bowl of water does not feel anything

Your example was poorly selected for your point: there is no frostbite risk in an 8F windchill if it is 35F outside. Even when it is below freezing, wind chill is not well tied to frostbite risk. Worse, while for a given person the risk of both goes up with lower wind chill, for a person with more body fat the frostbite risk is increased while the hypothermia risk is lowered.DaveC426913 said:Frankly, I think y'all are missing the point.
Wind chill factor and humidex are not comfort issues; they are health and safety indexes.
If a thermometer reads 35 degrees Fahrenheit outside and the wind is blowing at 25 miles per hour (mph), the windchill factor causes it to feel like it is 8 degrees F. In other words, your 98-degree body loses heat as though it is 8 degrees outside.
The WCF tells you how to dress and how to behave so as not to suffer from hypothermia, frostbite, etc.

I pulled those numbers from Google. Pretty sure I didn't suggest they were an example of frostbite risk in particular. I think you know that exposure and hypothermia can occur in a wide range of temps.russ_watters said:Your example was poorly selected for your point: there is no frostbite risk in an 8F windchill if it is 35F outside.

It's easy to pick apart an imperfect system so long as you don't have to offer a better one.russ_watters said:Worse, while for a given person the risk of both goes up with lower wind chill, for a person with more body fat the frostbite risk is increased while the hypothermia risk is lowered.
More broadly, since windchill is calculated for exposed skin, walking into the wind, it can be defeated by ducking and is not valid for adjusting for heat loss through quality insulated clothing, for which wind is largely irrelevant.
I don't see that as the core topic, more of an add-on.russ_watters said:And none of these issues of the science have anything to do with the additional issue of news hype.
Not sure how that's relevant.zuz said:Again, correct me if I'm wrong, but I thought if you put a thermometer in front of a fan on a cold day it would read the actual temp.

Humans aren't thermometers. Notably, we produce our own heat, and we lose heat via evaporation.

I don't mind knowing the windchill, butjim hardy said:I know reporting the weather is usually mundane - and what's wrong with calm ?
We need more calm-speak when a hurricane is approaching. Instead they feed hysteria
Seems a tad condescending.hmmm27 said:perhaps pandering to the ignorant keeps frostbite cases down.

Wind chill is the perceived decrease in air temperature felt by the body due to the flow of air. It is a measure of how cold it feels outside when the wind is blowing.
Wind chill is calculated using a mathematical formula that takes into account the air temperature and wind speed. The formula is based on the rate of heat loss from the human body to its surroundings.
No, wind chill is not an actual temperature. It is a calculated value that represents how the temperature feels to the human body. It is not a direct measurement of the air temperature.
Wind chill is measured using an instrument called an anemometer, which measures wind speed, and a thermometer, which measures air temperature. These values are then plugged into the wind chill formula to calculate the perceived temperature.
Yes, wind chill can be dangerous as it can cause the body to lose heat more quickly, leading to hypothermia or frostbite. It is important to dress appropriately and limit exposure to extreme wind chill conditions to prevent these risks.
