Kuhusu kifaa hiki cha kupigia hesabu
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.
Maswali yaliyoulizwa mara nyingi
Upepo ni nini?
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.
Upepo huwa baridi wakati gani?
It is defined for temperatures at or below 50 °F (10 °C) and winds above about 3 mph (5 km/h). Above those, wind has little cooling effect and the "feels like" equals the air temperature.
Subaboiti yaweza kutokea kasi kadiri gani?
When the wind chill drops below roughly −18 °C (0 °F) frostbite becomes a risk, and below about −28 °C (−19 °F) exposed skin can freeze in 30 minutes or less — sooner in more extreme wind chills.
Je, baridi ya upepo huathiri vitu, au watu pekee?
Upepo huondoa joto haraka kadiri mwili unavyopoteza joto, kwa hiyo hufanya watu na wanyama wahisi baridi zaidi, lakini hauwezi kupoa kama gari au bomba la maji chini ya halijoto halisi ya hewa.
Kwa nini upepo mwingi hauzidi kufanya upepo uwe baridi zaidi?
The formula uses wind speed to the power 0.16, which rises steeply at first and then flattens. Going from 5 to 15 mph drops the feels-like temperature a lot, but going from 40 to 50 mph changes it only slightly.
Je, kifaa cha kupigia hesabu kinafanya kazi katika mkondo wa joto na nyuzi za Selsiasi/km/h?
Naam, chagua beberu kuingia katika kiwango cha kuganda kwa nyuzi za Selsiasi na kilometa/h, na hutumika katika mlingano wa NWS.
Hali ya baridi kali inazuia mambo?
Zaidi ya digrii 50 °F (10 °C), au wakati upepo upo chini ya kilometa 3 hivi (5/h), upepo haupoa na halijoto inayofanana na joto la hewa ← kwa hiyo mashine hiyo hurudi noti badala ya nambari ya chini katika hali hizo.
API bustanini hutumia kifaa hiki cha hesabu kutoka kwenye mfumo wa sheria
Ipigie simu kifaa hiki cha kupigia hesabu kama Junse É not doot toder. Chochote unachoacha kinatumia kiwango kilekile cha mwisho ambacho ukurasa huu haujakamilika; parameta isiyojulikana ni 400, si sufuri kimya kamwe. Soma habari kamili za API docs →
