Abstract
The standard weather data in Osaka (new version), Nara, Kanazawa, and Wajima for ten years from 1980 to 1989 are developed. These data consist of several outdoor weather effects: air temperature, absolute humidity, direct radiation, diffuse radiation, cloud cover, wind direction, and wind velocity. Using the standard weather data, yearly variation of daily average, average daily variation for each month and histograms of daily average are calcurated. The above statistical properties are compared between the six data: these are the four data above, the old data in Osaka (1960-1969) and the data in Toyama. The comparison between the new data in Osaka and the old one shows that grobal radiation of the new one is more than that of the old one, it is remarkable in summer, the difference of the monthly summation between the two is about 130 [MJ/m^2 month] in July. In addition, the maximum grobal radiation of the old data is less than 24 [MJ/m^2・day] and that of the new one and the data in Nara is 30 [MJ/m^2・day]. Temperature of the data in Nara is about 2[℃] lower than that in Osaka all year round, and that in Kanazawa is 1-3[℃] higher than that in Wajima or Toyama.
