摘要
探讨了天气雷达色标配置规律,提出了两种改进的基本产品色标,利用实例对色标的改进效果进行对比分析。结果表明:改进后的色标可以使强度图的回波过渡性增强、回波中心更突出、阵风锋辨识度增强;速度图能更好显示出大风速区、急流、风切变和速度模糊、零速度线;谱宽图的过渡性增强,能更好反映出湍流强弱。两种改进的色标能有效满足视觉需求,并突出雷达图像中的关键信息。
In this paper,the configuration rules of weather radar product color codes are discussed,two kinds of improved color codes are presented and specific cases were used to inspect the effects. Some conclusions could be presented: the improved color codes can make the reflectivity echo's transition more obvious,may highlight echo center and enhance the gust front echo's visibility. The velocity echo can reflect the large wind region,jet stream,wind shear,velocity ambiguity and zero-speed line more effectively. The spectral width echo's transition can be more clearly,can reveal the intensity of turbulence more effectively. Two kinds of improved color codes can emphasize the key information as well as satisfy visual needs effectively.
