Ku saabsan Kalkaaliyahan
The heat index, or apparent temperature, is how hot it really feels when humidity is combined with the air temperature, and this heat index calculator computes it from those two inputs. The body cools itself by evaporating sweat, but humid air is already close to saturated so sweat evaporates slowly, the cooling falters, and it feels hotter than the thermometer says. The tool uses the U.S. National Weather Service Rothfusz regression, a multi-term fit of temperature and relative humidity, together with its standard low- and high-humidity corrections.
As a worked example, 90 °F air at 60% relative humidity carries a heat index of about 100 °F — ten degrees hotter than the reading — and pushing the humidity to 80% drives it past 110 °F. The calculator returns the feels-like temperature, how much hotter that is than the air, and a humidity table so you can see how quickly the danger rises as the air grows muggier at a fixed temperature.
The regression is most accurate around 80 °F (27 °C) and above with meaningful humidity; below about 80 °F it reports no heat stress because humidity has little effect on comfort in cool air. It also grades the reading into the NWS danger bands — caution, extreme caution, danger and extreme danger — so a heat index above 103 °F signals a real risk of heat cramps or exhaustion, and above 125 °F a high risk of heat stroke, which is vital for planning outdoor work, sport and travel in hot weather.
Su'aalaha badanaa la isweydiiyo
Waa maxay heerkulka heerkulka?
Heerkulka heerkulka, ama heerkulka muuqata, waa sida kulul ee ay dareemayaan marka dabacsanaanta la xiriira la isku daraa heerkulka hawada. dabacsanaanta sare hoos u dhigaa dabacsanaanta, sidaas darteed jirka ku shubta kulul oo aan si fudud u akhrin oo dareemaa ka kulul ka badan thermometer akhriyo.
Waa maxay foomka ay tani isticmaali?
The NWS Rothfusz soo noqnoqoshada: HI = −42.379 + 2.04901523T + 10.14333127R − 0.22475541TR − … (oo leh T in ° F iyo R in %), iyo hagaajinta si aad u hooseeya ama aad u sare ah daxalka. Waa ugu saxsan ee ku saabsan 80 ° F iyo ka kulul.
Maxaa ka dhigan heerarka khatarta?
Sicir-bararka: 80-90 ° F waa digniin, 90-103 ° F digniin aad u weyn, 103-124 ° F khatar (qallalan ama qallalan oo u badan) iyo 125 ° F ama ka sarreeya khatarta aad u weyn oo khatar sare ah oo ku saabsan xanuunka kulaylka.
Maxaa keena in qoyaanka qabow ka sii xun yahay?
In hawada qoyan, hadda ku dhow dabacsanaanta, dabacsanaanta ayaa hoos u dhacda, sidaas darteed jirka ayaa si xun u kulul oo 90 ° F oo isku mid ah ayaa dareemaya in ka badan 80% dabacsanaanta ka badan 30%.
Maxaa ka dhigaya xisaabinta in ay yiraahdaan "ma jiro isbeddelka heerkulka" maalin kulul?
Heerkulka index waa kaliya loo qeexay xaaladaha kulul - in ka badan 80 ° F (27 ° C) iyo kor. Ka hooseeya in, dabacsanaanta si fudud u beddeli sida hawada u dareemaan, sidaas darteed qalabka warbixinnada heerkulka hawada caadiga ah ka badan mid muuqata.
Sidee waa heerkulka index kala duwan oo ka dabaysha qabow?
Waxay yihiin hagaajinta ka soo horjeeda: heerkulka index qiyaasta ku daray qabow muuqata ka biyaha ku qabow, halka dabaysha qabow ka dhigi qabow muuqata ka dabaysha ku qabow. heerkulka index u baahan yahay heerkulka iyo biyaha ku qabow; dabaysha qabow u baahan yahay heerkulka iyo dhaqdhaqaaqa dabaysha.
Ma heerkulka index u maleynayaa hooska ama qorraxda?
Waxaa lagu xisaabiyaa hooska. iftiinka qorraxda tooska ah ayaa la kordhin karaa sida badan sida 15 ° F heerkulka la dareemay, sidaas darteed qiimaha dhabta ah ee dareemaya-sida ah ee dibadda qorraxda oo dhan waa ka sarreeyaa tirada xisaabinta this soo laabtay.
API — isticmaal xisaabinta ka code
Wici xisaabinta sida free JSON endpoint - key ma loo baahan yahay. Dib u soo dir qiimaha goobta hoos ku qoran sida parameters su'aal ama JSON. Wax kasta oo aad ka maqan tahay isticmaalaa default la mid ah ee boggani waa hore loo buuxiyey la; parameter aan la aqoon waa 400, marnaba ma aha zero maqan. Akhri dhammaan API xuquuqda →
