利用时空分辨率较高的中尺度气象数值模式模拟得到的边界层内的风温场，在国内首次推算了褐飞虱秋季在我国东部回迁的三维轨迹。结果表明三维轨迹揭示了褐飞虱秋季回迁方向是由东北向西南，迁飞时褐飞虱距地面高度是随时间波动变化的，三维轨迹能更好地描述褐飞虱迁飞的实际情况。
The three-dimensional trajectory of the brown planthopper in the eastern part of China was calculated for the first time in China using the wind temperature field in the boundary layer simulated by the mesoscale meteorological numerical model with high temporal and spatial resolution. The results showed that the three-dimensional trajectory revealed that the brown planthopper migrated in autumn from northeast to southwest. The height of the brown planthopper from the ground during the migration varied with time. The three-dimensional trajectory could better describe the actual situation of the migration of the brown planthopper.
