| 摘 要： | 探测仪器感应曲线发生变化，造成升速异常、等压面的温度、湿度错误、雷达〖CD*2〗气压高差偏大、时间〖CD*2〗高度线曲变化异常造成的规定高度上的风误差偏大，使部分资料或整份资料失真,影响探测准确性。本文主要从仪器的感应曲线变化后对各气象要素产生的影响进行分析，得出结论：不同的元件变性对气象要素产生的影响不同，气压变化的影响侧重于高差和升速，温度变化则侧重于规定等压面的温度绝对误差和规定等压面高度的偏差。采用绝对误差计算、加密气象要素计算等方法，结合图形、数据对比，可以确定感应曲线变化时间，从而及时、有效的对探测数据做出合适的处理，进一步提高探测数据的精准度。

| Abstract: | The veracity of the sounding data and weather forecasts would be influenced if the sounding instrument was degenerated. The sounding data, such as the height and meteorological elements of the isobaric surface, the ascending velocity of the balloon, and altitude difference profiles, are analyzed. The characteristics of different sounding instrument degeneration and discrimination methods are summarized. Using the method of absolute error calculation and intensive meteorological element calculation, combined with graphics, data comparison, the time to change for induction curves can be determined. Thus the sounding data can be treated timely and effectively, and the quality of the sounding data can be improved. |
