降水性鬃积雨云
积雨云是一种浓密的云，垂直厚度相当巨大，呈山脉或巨塔状。至少其上层的一部分通常平滑、纤维或条纹状，而且几乎始终呈扁平状。在这张放大的照片中，由于上层部分的多数云芽正从秃积雨云变为鬃云种，因而它们在1和2逐渐呈纤维状且模糊还清。上层部分总体仍为凸起圆顶中的一个，但尚未发展成砧云（砧状）。鬃状云通常伴有阵雨式降水（降水性附加特征），见右下15-20公里之外。在最高的塔顶附近是一小块积雨云性高积云。图中还有花椰菜状的浓积云云芽、一些中展积云，可能还有碎积云，由于拍摄角度的缘故，显得离相机更近。

鬃积雨云和积雨云性密卷云
在低压槽上和前方的不稳定空气中形成一条积云和鬃积雨云。主细胞被确定为鬃积雨云，因为它的一些上部具有明显纤维结构的积云状部分（云顶部分已开始冻结）。这个细胞的两侧是浓积云细胞（位于1、2、和3处），它们在其生命周期的不同阶段显示出一系列垂直范围。
还有一些由于积云状云线的部分扩展而形成的层积云、高积云和卷云。即使它们是在在母云达到积雨云阶段之前形成的，层积云和高积云也被确定为积雨性云。

有过冲云顶的砧状鬃积雨云
1和2处的两个稳定层暂时停止了该积雨云细胞的垂直发展。由于在第二个稳定层的扩散有明显的纤维结构的圆形部分，云已经从秃积雨云转变为砧状鬃积雨云。
明显的过冲云顶似乎由水滴组成，因为上部清晰地限定并且没有明显的纤维或条纹纹理。
在第一个稳定层下扩散的云被识别为积雨云性高积云。浓积云和中云云线在积雨云细胞前面。

砧状鬃积雨云和秃积雨云
图为积云向积雨云的发展过程。右侧是中展积云典型的小凸起和云芽，而后是浓积云清晰的轮廓、更大的垂直厚度以及上部隆起的花椰菜状。在图的中间，云的上部正变得模糊和扁平，云块发白，轮廓不清，这就是典型的秃积雨云。在左侧，云呈纤维状，已发展成为鬃积雨云。在左侧边缘正好可看到云砧（砧状云），但其大部分被灰色云遮挡。在头顶之上，由于云砧扩散，一层浓密的积雨云性密卷云已形成。

Cumulonimbus capillatus praecipitatio
Cumulonimbus capillatus over the semi-arid region of Wyoming is seen in this photograph. A tapering column of precipitation is evident. The tapering is due to the evaporation of the precipitation as it falls through the dry environment so that very little reaches the ground. The precipitation probably consists of snow pellets above the apparent melting level.
The symmetrical shape of the anvil and vertical shaft of precipitation indicate that winds were light throughout the lower and middle troposphere.
The area was under the influence of a warm, high-pressure area in the middle troposphere.

Isolated Cumulonimbus capillatus with Cumulus congestus and mediocris
The isolated tall, narrow Cumulonimbus capillatus in the centre of the picture is located just seawards of a long, narrow island about ten kilometres off the south coast of Florida. The cloud has a primary up-draught region the top of which is near 1, but the updraught is composed of several surges seen at 2, 3 and 4. The cloud is leaning slightly to the south (away from the camera) due to a weak northerly shear in the lower and middle troposphere. Strong north-easterly winds in the upper troposphere have led to the spreading downwind of the glaciated upper section of the cloud to form an elongated anvil. Virga can be seen falling from the anvil at 6. This is undoubtedly ice because of the high altitude. Adjacent to the main cloud, the lifting of a moist, stable layer has produced a patch of Altocumulus stratiformis cumulonimbogenitus at 7. All other Cumulus in the picture range from mediocris to the largest congestus at 8. An upper-tropospheric cold low located 400 kilometres to the south-east was responsible for a north-easterly airflow at upper levels. The lower tropospheric flow was weak from the east-south-east since the subtropical high-pressure ridge was orientated E-W well to the north of the area.

Cumulonimbus capillatus incus
A complex of Cumulonimbus capillatus clouds with anvils is visible at 1 and 3 in different growth stages. The mature updraught at 1 has cumuliform updraughts restricted to the upper portion and streaks of precipitation falling at 2. The updraught at 3 is considerably younger, and is developing into an anvil left behind by a now-dissipated Cumulonimbus. The sharply-defined updraught bases at 4 and 5 contrast with the indistinct cloud base associated with the mature storm at 1. Patches of Cirrus, as for example at 6, are approaching the Cumulonimbus complex from the west, having been generated by thunderstorms over the mountains to the west. Numerous patches of suppressed Altocumulus are scattered in the clear air behind the system. Distant Cumulus shows some limited vertical growth. The situation was typical of High Plains convection, since the axis of an upper-air ridge of high pressure moved eastwards, and unstably stratified air returned. A weak cold front had passed through Colorado two days earlier.
