Cloudform

This article which was a sketchy summary of my investigations, contains also the laws of the motions of the lower cloudforms, such as cumulus, cumulo-stratus, conus.

These observations comprise four regular observations daily on the barometer, thermometer, hygrometer, and other instruments, giving the pressure,. temperature, humidity, cloudiness, cloudform, direction, and force of the wind, and the rainfall.

The next five plates depict our commonest and, in its infinite variety, most beautiful cloudform, the cumulus.

The flyer or gliding pilot knows well the rising air current under cumulus bursts; their flat bottoms show the exact cold-air level at which condensation into cloudform took place.

Halos are caused by light shining through ice cloudform, usually marking the advance of a warm front — with rain.

Over five miles up, all cloudform is cirrus in type, being composed of ice.
