2008年7月18日和19日，在中国大陆首次利用无人机探测手段对台风“海鸥”（0807号）进行了探测，根据19日台风减弱为热带风暴过程中的飞行探测资料，初步分析结果如下：飞行高度500 m，飞行时间近3小时，距离台风中心最近距离约为100 km，获取了探测期间的全部气象要素数据（温度、相对湿度、气压和风速），数据获取率达到90%以上。探测期间内的气压平均值为949.1±9.7 hPa，温度平均值为24.2±1.3℃，探测期间内，无人机基本处于降水云系中，故相对湿度较高，平均值为（88.4±6.1）%。通过对探测数据的初步分析，说明这种小型无人机具有探测台风边界层气象要素的能力。

Observation of typhoon “Kalmaegi”（NO.0807） by using unmanned aerial vehicle (UAV) was carried out on 18 and 19 July, 2008 for the first time in China mainland. According to the UAV-observing data during the weakening process of typhoon to tropical storm on 19 July, 2008, some preliminary analysis was presented in this paper. The preliminary results show that: (1)the UAV′s cruising altitude was about 500 m and the nearest distance to the typhoon centre was about 100 km. All the meteorological elements data (temperature, relative humidity, pressure, wind direction, and wind speed) were obtained during observation period and the data acquisition rate exceeded 90%. (2)The average value of pressure was 949.1±9.7 hPa, and temperature was 24.2±1.3℃. (3)During the observation period, UAV was almost within the precipitation cloud, and the average of relative humidity was about (88.4±6.1)%. The preliminary analysis suggests that this model UAV has the capability to observe the typhoon boundary layer.
