Heat Indexని ఎలా లెక్కించాలి

Heat Index అంటే ఏమిటి?

The heat index (apparent temperature or "feels like") combines air temperature and relative humidity to indicate how hot it actually feels to the human body. High humidity prevents sweat from evaporating, reducing the body's cooling ability.

సూత్రం

Heat index ≈ −42.379 + 2.04901523T + 10.14333127RH − 0.22475541T×RH + ... (complex formula)

HI: Heat Index (°F)
T: Air Temperature (°F)
RH: Relative Humidity (%)

1Uses the Rothfusz regression equation (NWS standard)
2Valid for temperatures ≥ 80°F (27°C) and humidity ≥ 40%
3Calculated from 9-term polynomial regression
4Danger levels: Caution >90°F, Extreme >103°F, Danger >125°F

పరిష్కరించిన ఉదాహరణలు

ఇన్పుట్

95°F, 60% humidity

ఫలితం

Heat index ≈ 108°F — Danger zone

ఇన్పుట్

95°F, 20% humidity

ఫలితం

Heat index ≈ 87°F — Caution zone (desert-like)

తరచుగా అడిగే ప్రశ్నలు

Is heat index the same as "feels like" temperature?

Heat index and "feels like" are similar concepts, but heat index specifically accounts for humidity's effect on the body's cooling through sweating.

At what heat index is it dangerous?

Heat index above 103°F creates risk for heat exhaustion. Above 125°F, heat stroke risk increases dramatically even for healthy people.

Why does humidity matter in hot weather?

Humidity prevents sweat from evaporating, which is your body's primary cooling mechanism. High humidity traps body heat and raises core temperature faster.
