Malunga nale Calculator
Wind chill is how cold the air actually feels on exposed skin once moving air is factored in, because wind strips away the thin insulating layer of warmed air around the body and speeds up heat loss. This wind chill calculator uses the current U.S. National Weather Service formula (adopted in 2001): in imperial units, WC(°F) = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, with T the air temperature in °F and V the wind speed in mph; the metric version, WC(°C) = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T·V^0.16, uses °C and km/h.
As a worked example, an air temperature of 20 °F with a 15 mph wind feels like about 6 °F — roughly 14 degrees colder than the thermometer reads. Raise the wind and the chill deepens, but with diminishing returns, since the V^0.16 term flattens out at high wind speeds. The calculator shows the feels-like temperature, how much colder that is than the actual air, and a table of wind chills across a range of wind speeds so you can see the trend.
The formula is only defined for cold, breezy conditions — at or below 50 °F (10 °C) and winds above about 3 mph (5 km/h) — so above those the "feels like" simply equals the air temperature. Beyond comfort, wind chill matters because it governs how fast exposed skin can freeze: the tool flags frostbite risk, which becomes serious once the wind chill drops below about −18 °C (0 °F) and can freeze skin in under 30 minutes in extreme cold.
Imibuzo ebuza rhoqo
Yintoni ifomula yomoya obandayo?
Ifomula yeNWS (2001) kwiyunithi ye-imperial yiWC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, nge-T kwi °F ne-V kwi mph. Imodeli ulahleko lobushushu ukusuka kwisikhumba esimnyama njengoko umoya ususa umphezulu opholileyo oqinileyo ojikeleze umzimba.
Xa i-wind chill isebenza?
Ichazwe kubushushu obungaphantsi kwe-50 °F (10 °C) kunye nomoya ophezulu malunga ne-3 mph (5 km/h). Ngapha koko, umoya unefuthe elincinci lokupholisa kwaye "iziva ngathi" ilingana nobushushu bemoya.
Ingaba isifo sokutshisa imilenze sivela ngokukhawuleza kangakanani?
Xa umkhenkce womoya uphantsi kwe-18 °C (0 °F) ukutyhala okubandayo kwenziwa kube ngumngcipheko, kwaye ngaphantsi kwe-28 °C (19 °F) ulusu olutyhafayo lunokutyhala kwimizuzu engama-30 okanye ngaphantsi - kuqala kwimkhenkce yomoya enamandla.
Ingaba ukutshisa umoya kubangela ukuba izinto zitshise, okanye abantu kuphela?
Kuphela izinto eziphilayo, ezishushu kunemoya. Umoya oshushu ulinganisela ukuba iqulethe ntoni iqulethe iqulethe ubushushu, ngoko ke yenza abantu kunye nezilwane zizive zibanda, kodwa ayikwazi ukufudumeza into njengemoto okanye umbhobho wamanzi ngaphantsi kobushushu bemozulu.
Kutheni umoya ongaphezulu ungaqhubeka usenza ukuba kuzive kubanda ngokuhambelana?
Ifomula isebenzisa umlinganiselo womoya ukuya kwi-power 0.16, onyuka ngokuthe tye kuqala kwaye emva koko ujikeleze. Ukusuka kwi-5 ukuya kwi-15 mph ukhupha ubushushu obuziva ngathi buninzi, kodwa usuka kwi-40 ukuya kwi-50 mph utshintsha kuphela ngokuncinci.
Ingaba i-calculator isebenza kwi °F/mph kunye ne °C/km/h?
Ewe. Khetha i-imperial ukungenisa i-°F ne-mph okanye i-metric ye-°C ne-km/h, kwaye isebenzisa i-NWS ehambelanayo. Ii-frostbite ze-equation zivavanywa kwi-metric scale ngaphakathi ukuze zombini iinkqubo zeyunithi zivumelane.
Kwiqondo lobushushu eliphi imvula yomoya iyeka ukuba yinto ebalulekileyo?
Ngapha kwe-50 °F (10 °C), okanye xa umoya ungaphantsi kwe-3 mph (5 km/h), umoya unefuthe elincinci lokupholisa kwaye ubushushu obufana nobuziva bulingana nobushushu bemoya - ngoko i-calculator ibuyisela umbhalo endaweni yenani eliphantsi kule meko.
