By using the information of high impact weather events and dialing num bers of weather service phone (named 12121)，the distribution of estimated meteo rological attention degrees of general public was calculated. Further more, the social benefit values of public weather service through willingness to pay (WTP ) are also estimated. Taking Xi’an city as an example, it chooses occurring d ays of ten high impact weather events closely related to general public from 200 4 to 2007，which are granted as potential meteorological risk resources, i.e. hi gh temperature,heat wave，sultry weather,scattered precipitation, moderate sho wer,heavy rain,thunderstorm,snow, fog or haze and consecutively rainy day. Accor ding to demography information and average local phone charge, the total WTP values were calculated respectively. The results show that there were approximat ely 1174.854 ten thousand Yuan/year on temperature weather events, about 4973.39 4 ten thousand Yuan/year on precipitation events, roughly 311.269 ten thousand Y uan/year on thunderstorm and probably 471.637 ten thousand Yuan/year on fog or h aze weather. The result is helpful for quantitative judgments about societal inf luence of publicmeteorological services.
