为了说明冬天空气的温度以及风速对人体冷暖感觉的影响,欧美国家的关气预报中普遍采用风冷温度的概念( wind-chill temperature )。风冷温是一个当量的环境温度,当人处于静止空气的风冷温度下时其散热量与人处文际气温、实际风速下的散热量相同。从散热计算的角度可以将人体简化为直径为25cm、高175 cm、表面温度为 30℃...
1.Based on the data of temperature and wind speed for the meteorological observation stations in China,and according to the latest WCT formula,this paper analyzed the wind-chill temperature changes in winter over China during the past 50 years.风寒温度是冬季表征人体热舒适度常用的参数,也是气候变化...
(这里的“cold keen wind”暗示了低温的“temperature”) 出处:《白鲸记》(Moby-Dick) by Herman Melville 句子:"It was a very cold winter; how cold I best know myself, for I was there, and still carry about me the cumulative chill incurred." 翻译:“那是一个非常寒冷的冬天;有多冷我最清楚...
A method for controlling the temperature of an enclosure by opening or lowering curtains based on the difference between inside and outside temperatures and the prevailing wind velocity, direction, and wind chill. In one example, temperature of a cow barn is controlled, in part, by determining ...

Why is wind chill so dangerous? Moore likened the process of how wind affects body temperature to blowing on a bowl of hot soup in order to cool it down: "As wind blows across our bodies, it takes the heat we naturally emit and blows it away," Moore said. "The faster the wind spee...
