Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Waa maxay foomka dabaysha qabow?
Foomka NWS (2001) ee unugyada boqortooyada waa WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, oo leh T ° F iyo V mph. Waxay muujineysaa khasaaraha kulaylka ee maqaarka qaawan sida dabaysha ay ka saarto darajooyinka dhalaalaya ee jirka.
Goorma ayaa dabaysha qabow ku dhaqan?
Waa in la qeexo heerkulka ama hoos u 50 ° F (10 ° C) iyo dabaysha ka sarreeya oo ku saabsan 3 mph (5 km / h). Ka sarreeya kuwa, dabaysha waxay leedahay saameyn yar oo qabow iyo "u muuqda sida" waa isku mid ah heerkulka hawada.
Sidee degdeg ah ayaa frostbite dhici kartaa?
Marka dabaysha qabow hoos u dhac ku dhaca hoos u dhaw -18 ° C (0 ° F) frostbite noqon kartaa khatar, iyo hoos u hoos -28 ° C (-19 ° F) maqaarka la arkay waxaa la qaboojin karaa 30 daqiiqo ama ka yar - ka hor in ka badan dabaysha qabow oo aad u daran.
Ma dabaysha qabow waxyeello u geystaan, ama dadka oo keliya?
Dhinaca kale, dabaysha qabow waxay tijaabisaa sida degdega ah ee jirka kulul uu ku lumin karo kulaylka, sidaas darteedna dadka iyo xayawaanka waxay dareemaan inay ka qabow yihiin, laakiinse ma qaboojin karaan wax sida gaari ama biyo-biyood oo hoos u dhaca heerkulka hawada dhabta ah.
Maxaa dabaysha ka badan ma sii wadaan inay dareemaan si la mid ah oo qabow?
Foomka isticmaalaa dhaqdhaqaaqa dabaysha in awoodda 0.16, taas oo kor u kacdo si tartiib ah markii ugu horeysay oo markaas flattens. Going ka 5 ilaa 15 mph hoos u dareemaan-sida heerkulka badan, laakiin ka socda 40 ilaa 50 mph u beddelo kaliya wax yar.
Ma xisaabinta shaqada labada ° F / mph iyo ° C / km / h?
Haa. Dooro Imperial si aad u gasho ° F iyo mph ama metric for ° C iyo km / h, iyo waxay ku habboon tahay isku midka NWS. The frostbite xaddidaadaha waxaa lagu xukumay on scale metric gudaha si labada nidaamyada unit ku heshiiyaan.
Maxaa heerkulka waa dabaysha qabow joojiyaan waxtar leh?
Korka 50 ° F (10 ° C), ama marka dabaysha hoos ku saabsan 3 mph (5 km / h), dabaysha waxaa jira saameyn yar oo qabow iyo heerkulka dareenka-sida ah waa isku mid ah heerkulka hawada - sidaas darteed xisaabinta ku soo laabtay qoraalka ka badan oo ah tirada hoose ee xaaladahaas.
