Based on the equalization conception of basic public weather services, considering relevant research results, we selected the statistical data of 2013, summarizing 10 indicators, and divided into three categories with factor analysis. Then we build a multilevel evaluation index system of equalization of basic public weather services. According to AHP to construct the hierarchical graph, we quantitatively calculated the relative weights of the factors of the rule layer and the index layer by consulting the experts to obtain judgment matrix. Through the application of grey relational comprehensive evaluation model, we conducted an empirical analysis of the national 31 provincial equalization of basic public weather services in 2013. The results show that the overall level of the equalization of basic public weather services in China is low, and the unbalanced provincial development, ladder features from East, Central, and West China are found. Provinces can be divided into three levels: high, medium, and low. Besides, there is positive correlation between the level of the equalization and the provincial economic strength, financial revenue scale, and comprehensive development capacity.
