Assess comfort level from dew point and temperature based on humidity thresholds.
输入温度和相对湿度,计算露点温度、水汽压、体感温度及舒适度等级。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Dew point | Td: cool to saturation at constant p | WMO No.8 |
| Comfort zones | <10 dry; 16–21 muggy; >21 oppressive | CMA comfort grades |
| Condensation risk | Condensation if surface < Td | EN ISO 13788 |
| Perceived link | Links to muggy perception | Steadman 1979 |
| Magnus inversion | Td = 243.5·ln(e/6.112)/(17.67−ln(e/6.112)) | Bolton 1980 |
| Accuracy | <0.4 °C error 0–50 °C | Lawrence 2005 |
输入气温与相对湿度,利用 Magnus-Tetens 公式计算露点温度和水汽压,结合温度湿度指数(THI)判定人体舒适度等级,并在高温高湿时计算酷热指数评估中暑风险。
