You should be able to add any wind speed sensor you are using. I don't have anything to monitor windspeed so you can see I set it to a value of 10 just for testing. Having said all this, I understand the appeal of wanting to solve the original problem, and I'd like to have the ability to do exponents in here's a quick and dirty hack of a wind chill calculator. The wind will determine how QUICKLY the bird feeder cools off, but won't affect the final temperature it ends up at. It's useful for figuring out how warmly you should dress to avoid frostbite, but it doesn't have any effect on inanimate objects, and would not work for birds either, as they have different metabolisms. Remember that the formula you're looking at is specifically designed for figuring out how much heat a human body will lose under certain conditions. Where T = degrees Fahrenheit and V = wind velocity in miles per hour.Īnd here's a simpler approximation that will produce results within a degree or two of the more complex formula. Here's the formula for silly American units: The accuracy of your instruments for measuring wind and temperature will probably be +/- 5% or more, so an approximation that's within a degree or two will be good enough. The best way to avoid the hazards of wind chill is to check the weather forecast before going outside and to be prepared by dressing warmly. Exposed skin at very cold wind chills can freeze in only minutes. As you do so, keep in mind the biggest wind protection item that can be a lifesaver, and the best part is that you don’t have to wear it a windshield.You don't really need to reproduce the exact formula to achieve your goal.Ī simplified approximation will get you close enough for practical purposes. The wind chill index is not actually a real temperature but, rather, represent the feeling of cold on your skin and is expressed in temperature-like units. Therefore, it’s important to seal these leaks with versatile items such as a balaclava or scarf, drawstrings, and Velcro. The most crucial part of windproofing is seamlessness otherwise, the money you shell out on pricey windproof gear is all in vain if you have weak points from which the heat is escaping.Īt motorcycling speeds, the small gap between your collar and helmet or jacket cuffs and gloves quickly become gaping holes in your cold defenses. It involves sealing in the heat to prevent it from being lost in the rushing air. We also recommend heated gear such as a heated seat and grips, given that you have a great power source (your bike) readily available. Excellent bottom layers are a snug-fitting wool or poly fleece coupled with insulating layers. It’s a lifesaver in motorcycling and other cold-weather activities. Let’s explore a few foolproof ways of fighting off the wind chill on a motorcycle. How to Combat Wind Chill While Riding a Motorcycle
