cumulonimbus cloud

Combined the fractal dimension with the 2 order statistical features of Gray Gradient Co occurence Matrix ( GGCM) of 4 kinds of basic clouds pictures ( Cirrus, Cumulus, Cumulonimbus and Layer Cloud), the clouds are classified and recognized.

将4种基本云类（卷云、积雨云、积云和层云）的分数维和灰度梯度共生矩阵（GGCM）的二次统计特征结合起来，对云类进行分类与识别。

The decay of a single cell cumulonimbus cloud is rapid and seldom exists for more than half an hour.

积雨云云消逝飞快，它的存在几乎不会超过半小时。

Secondly, the research data, which use the cloud classification productions of National Satellite Meteorological Center as types' labels, are divided into Land, Mixed cloud, Altostratus or Nimbostratus, Cirrostratus, Cirrus Spissatus, Cumulonimbus and Stratocumulus or Altocumulus.

第二，每个数据的类别标签参考国家卫星气象中心的云分类产品结果，将实验数据划分为地表、混合像元、高层云或雨层云、卷层云、密卷云、积雨云以及层积云或高积云7类。

A cumulonimbus cloud rises high into the sky and usually produces storms.

积雨云上升到空中，通常会带来暴风雨。
