云迹 meaning in English
cloud track
cloud trail
Examples
- The result shows that the cloud motion winds have well quality and higher density , and the wind structure of weather system can be seen clearly from them
结果表明，反演出的云迹风质量好，密度很高，清晰地反映出天气系统的风场结构。 - An important step in deriving winds from geostationary meteorological satellite data is selecting the clouds which move slowly and go with the wind , which is called tracers
摘要云迹风反演中的一项很重要的工作是选取随风移动、变化缓慢的云，即示踪云。 - Then cloud motion winds are derived from these tracers and after a circumfluence analysis on the cloud motion winds , the cloud motion winds are compared with the rawinsonde winds
对用该方法选取的示踪云进行云迹风反演，然后对反演出的云迹风进行环流分析，并与探空风进行比较。 - In this paper we studied the textural features extraction , remote sensing images classification and bp neural network techniques and their applications in the meteorological problems such as recognition of the cloud cluster feature , cloud - drift wind retrieval and heavy rain process analysis etc . to the question of the low precise recognition of satellite images by using spectral features , the proposed approach assumes to perform a multiple analysis based on an advisable decision - making model by first developing a mixed pixel model which was based on the textural features of images , and then improving the recognition intelligence
本文对模式识别领域中的图像纹理特征提取、遥感图像分类、 bp神经网络与纹理特征组合分类等方法，以及它们在云团属性识别、云迹风反演和暴雨过程分析等气象问题中的应用作了研究。针对过去利用图像光谱亮度特征进行识别分析气象卫星图像准确度不高的问题，本文提出了发展混合像元的分解模型，以图像的纹理特征为基础，提高图像识别的智能水平，以实现在分析决策模型的支持下，快速准确的复合分析的解决方案。
