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.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani chinyezi cha upepo formula?
The NWS formula (2001) in imperial units is WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, with T in °F and V in mph. It models heat loss from bare skin as wind strips away the thin warm layer around the body.
Kodi nthawi iti yomwe chilala cha mpweya chimagwira ntchito?
Zimafotokozedwa kuti ndi kutentha kwa 50 °F (10 °C) kapena pansi pake ndi kuwala kwa 3 mph (5 km / h).Pambuyo pa izi, kuwala kuli ndi zotsatira zotentha kwambiri ndipo "kuwoneka ngati" kumafanana ndi kutentha kwa mpweya.
Kodi ndi nthawi iti yomwe imatha kuchitika?
Pamene kutentha kwa mpweya kumagwa pansi pa −18 °C (0 °F) kupweteka kwa mpweya kumayamba kukhala vuto, ndipo pansi pa −28 °C (−19 °F) khungu limatha kupweteka m'maola 30 kapena pang'ono - nthawi yaitali kwambiri pa kutentha kwa mpweya.
Kodi chinyezi cha mpweya chimakhudza zinthu, kapena anthu okha?
Chilala cha mpweya chimawerengera momwe thupi lotentha limathamangitsa kutentha, motero kumachititsa kuti anthu ndi zanimalo azisangalala ndi kutentha, koma sichingathe kuwala zinthu monga galimoto kapena valavu ya madzi pansi pa kutentha kwa mpweya.
N’chifukwa chiyani mpweya wochuluka umachititsa kuti mpweya ukhale wotentha kwambiri?
Formula amagwiritsa ntchito kuwala kwa mpweya ku mphamvu 0.16, yomwe imakwera mosalekeza panthawi yoyamba ndipo kenako imathamanga. Kuchokera 5 mpaka 15 mph kumathamanga kutentha kwa mpweya, koma kuchoka ku 40 mpaka 50 mph kumasintha pang'ono.
Kodi calculator ntchito m'ma ° F / mph ndi ° C / km / h?
Yes. Choonitsani Imperial kuti mupite ku °F ndi mph kapena metrical kwa °C ndi km / h, ndipo imagwiritsa ntchito NWS yogwirizana ndi equation. The frostbite mlingo ndi kuonedwa pa metric scale mwamsanga kuti onse awiri unit systems agree.
Kodi kutentha kwa mphepo kumatha kulephera kukhudzana ndi kutentha kwa madzi?
Pambuyo 50 ° F (10 ° C), kapena pamene upepo ndi pansi pa pafupifupi 3 mph (5 km / h), upepo ali ndi zotsatira zotentha pang'ono ndi kuzindikira-mwachitsanzo kutentha ndi chimodzimodzi ndi kutentha kwa mpweya — kotero calculator amabwerera mfundo kuposa ochepa ziweto m'madera amenewa.
