Study on the dynamics of city fires concerns the safety of human lives and properties. In this paper, the distribution of city fires is investigated, as well as the relation between fire frequency and weather. The frequency-size distribution and frequency-interval distribution of city fires are found to satisfy power-law relation, suggesting that there is connection between large and small fires and large fire frequency can be predicted with that of small fire. The correlation between fire frequency and weather parameters such as temperature and humidity is also studied. It is shown that fire frequency changes with these weather parameters, indicating that city fire frequency can be forecasted with weather parameters. The results are expected to reveal the global, complex characteristics of city fires, that is, the dynamics of city fire system. The study is also an approach to compose city fire danger rating method, just like the existent forest fire danger rating method, authors=null, authorsList=null, authorCompany=null,
