稻纵卷叶螟标记蛾迁飞轨迹的数值模拟

NUMERICAL SIMULATION OF THE TRAJECTORY OF MARKED MOTH OF RICE LEAF ROLLER ( CNAPHALOCROCIS MEDINALIS )

选用一维ＴＫＥ模式，以国家气象局的常规气象资料为基础，以Ｅ－ε闭合求其数值解，模拟出边界层内任意迁飞高度上的风温要素值，再将昆虫迁飞行为参数化，据此模拟了稻纵卷叶螟标记蛾的迁飞轨迹。

The trajectory analysis of the marked moth of rice leaf roller, which was released in the late July of 1980, was presented. The one dimension TKE closure scheme (E ε scheme) was adopted to simulate the wind and temperature profiles based on the conventional surface and 850 hPa wind and temperature data of Chinese National Meteorological Bureau, and the migrating behaviour of insects was parameterized as some proper mathematical expressions. Then the flight pathways were estimated by a simple algorithm to output the hourly episodes of the marked moth which consists of the latitude, longitude and flying altitude.
