Water Supply and Meteorological Conditons in Shijiazhuang City

The relationship between water supply in Shijiazhuang city and meteorological conditions were analyzed by using the successive regression.The result shows that the water supply in the city has a positive correlation with the temperature in all seasons,with precipitation,wind and humidity in summer,a negative correlation with precipitation,wind and humidity in winter,spring and fall,and an obvious correlation with some synthetic meteorological indexes such as:sultry index,and with special weather,for example,the foehn.A regression equations reflect the character that water supply is largest in summer (temperature is highest,humility is also highest) and least in winter (temperature is lowest).
