在Python中计算风寒系数（WCF）或风寒指数（WCI）

W ind-chill 或W indchill 是由于空气流动，身体在暴露的皮肤上感觉到的空气温度的感知下降。风寒的作用是增加热量损失的速度，并使任何较热的物体更快地降低到环境温度。
以下是加拿大、英国和美国在 2001 年采用的标准公式来计算和分析风寒指数：

T_wc(WCI) = 13.12 + 0.6215T_a – 11.37v^+0.16 + 0.3965T_av^+0.16
where

T_wc = Wind Chill Index (Based on Celsius temperature scale)
T_a = Air Temperature (in degree Celsius)
v = Wind Speed (in miles per hour)

编程需要懂一点英语

例子：

Input: 
Air Temperature = 28
Wind Speed = 80
Output: 30
Calculation done using the above formula:
WCI = 13.12 + 0.6215 * (28) - 
      11.37 * (80)**0.16 + 
      0.3965 * 28 * 80**0.16

Input: 
Air Temperature = 42
Wind Speed = 150
Output: 51
Calculation done using the above formula:
WCI = 13.12 + 0.6215 * (42) - 
      11.37 * (150)**0.16 + 
      0.3965 * 42 * 150**0.16

# Python program to calculate WCI
import math
  
# funtion to calculate WCI
def WC(temp, wi_sp):
      
    # Calculating Wind Chill Index (Twc)
    wci = 13.12+0.6215*temp- 11.37*math.pow(wi_sp, 0.16) + \
          0.3965*temp*math.pow(wi_sp, 0.16)
    return wci
      
# Taking the Air Temperature (Ta) 
temp = 42
  
# Taking the Wind Speed (v) 
wi_sp = 150
  
print("The Wind Chill Index is", int(round(WC(temp, wi_sp))))

输出：

The Wind Chill Index is 51
