Suppose that:
Place A has Temperature $33^o C$, Humidity $57\%$, Wind $14\;km/hr$, and Precipitation $20\%$
Place B has Temperature $37^o C$, Humidity $11\%$, Wind $14\;km/hr$, and Precipitation $0\%$
Which place would feel better?
美国国家海洋和大气局计算视温的公式为:
<代码> AT = -2.7 + 1.04*T + 2.0*e -0.65*v 代码>
其中AT和T(空气温度)为℃,e为蒸汽压,单位为kPa, v为10m风速,单位为m/sec。
大多数气象组织在其天气报告中包括计算的视温。
但最终,不同的人确实喜欢不同气候的感觉,所以它变得有些主观。我不确定大部分人是否同意,但我确实更喜欢潮湿炎热天气的感觉,而不是同样温度的干燥炎热天气。我还认识一些人,只要气温降至华氏80度(26.7摄氏度)以下,他们就会发抖。所以当你说“感觉好些了”时,任何估计的有效性都是有争议的。< / p >
Also note, it'd seem hard to incorporate the probability of precipitation into a comfort metric in a meaningful way. It either rains or it doesn't; a 20% POP day feels the exact same as a 0% POP day, all other conditions being equal, if the rain doesn't occur. Now obviously getting soaked may not be the cup of tea for everyone... but there are some!
