The EA method for constructing a reference weather year was compared with the SHASE and some modified EA methods. The weather data used for the comparison were 15 years daily data at 797 stations in Japan, calculated from Expanded AMeDAS (EA) Weather Data. The following results were obtained. 1) 60% of the typical months selected by the EA method weg the same as those by the SHASE method. 2) Among the five weather parameters, e.g., temperature, humidity ratio, solar irradiation, precipitation and wind speed, except for temperature, monthly mean values and daily cumulative distribution functions (CDFs) of the typical months selected by the EA method were closer to those of the 15 years than those selected by the SHASE method. 3) As for temperature, monthly mean and daily CDFs of the typical months selected by the EA-DWT method were the closest to those of the 15 years.
