摘要
With the development of tourism, the security of tourist sites is becoming greatly important for travelers. However, unstable weather conditions can often generate latent hazardous whirlwinds. Dust devils are such minor whirlwinds which can of course put tourists in considerable danger. This paper presents an effective dust-devil monitoring system and, as an example, reports on its application at the Summer Palace in Beijing, China. The proposed method uses three mini weather radars to form non-collinear observations. Through comparison with the conventional volume velocity processing (VVP) wind retrieval algorithm, we are able to demonstrate the superiority and advantages of the proposed approach, thus showing promise for use in other tourist sites and for protecting the lives and property of tourists.
