[Objective] The aim was to analyze the suitability of climatic factors for broad bean in Kunming. [Method] The suitability model of broad bean growth and development was established, involving temperature, rainfal , and sunshine, with consideration of bioecology characters of broad beans, in order to make further analysis of suitability of meteorological factors. [Result] Under average climate condition, temperature and sunshine suitability kept higher in the whole growth stage, but rainfal suitability was lower. Hence, lower temperature and insufficient rainfal are limiting factors of broad bean yield. Based on analysis of meteorological factors in 2013, it suggested that temperature and sunshine suitability kept higher in 2013, but rainfal suitability only reached over 0.6 in seedling stage, with rest below. [Conclusion] In the whole growth stage of broad bean in 2013, comprehensive meteorological factors kept middle or higher level and the suitability model reflects suitability of meteorological factors to crops in an objective way, which provides references for improving meteorological services.
