哈尔滨机场冷涡雷暴预报方法初探

The Preliminary Study of Cold Vortex Thunderstorms in Harbin Airport

本文通过用数值预报产品对冷涡雷暴分析,得出数值预报的形势场、抬升指数、K指数、垂直速度等,对提前预报冷涡雷暴有很好的指示作用。结合卫星云图、雷达回波图,能更好的监控冷涡雷暴的发展演变,为飞行安全提供有力保障。

By analyzing cold Vortex thunderstorm on numerical weather prediction products, we found that many numerical weather prediction products had good instructions on forecasting cold vortex thunderstorms ahead of, such as the situation in the field of numerical weather prediction, uplifting index, K index, and vertical speed. Combining satellite imagery and radar echoes, we could better monitor cold Vortex thunderstorm evolution, and serve for flight safety.
