Why Cumulus clouds at the bottom of the "cut"?

You had to notice that Cumulus clouds from below as if to gently "cut" a huge pair of scissors? That is between the earth and the lower part of these clouds is always a clear space, and it is the same in all those clouds. The effect is very beautiful. As the photographers and cameramen — "watchable". I wonder how it turns out in nature is such a spectacular picture? For a long time scientists could not answer this seemingly simple enough question about this phenomenon of nature. And only recently got into the whole "technology" with these clouds. It turned out that the evaporation of water from the ground steam rises gradually. This means that it first creates a layered solid cloud. But this fog (pairs always in the form of fog) tends to rise even higher. However, he begins to condense. And this leads to heat generation. Simply put, the moisture starts to evaporate already within the clouds, forming at the same time in several points of the cloud, tiny droplets. However, they are not deposited on the larger droplets and rise pile up. Actually, hence the name Cumulus clouds. Cumulus, olacapato: ru.wikipedia.org There is another explanation, which looks more scientific. As you know, Cumulus clouds we see only in the summer. But why at this time of year? The point is that with the onset of spring, the soil begins to warm up and "breathe." While wet at the bottom (near the ground) the air is warmed and turns into a barely visible vapor. If a Sunny day to look at a plowed field, it can be easy to spot, as above him, swaying in the air. In fact, when we see not the air itself, but transparent is the flow of steam. Rises, steam begins to form in the layered cloud. It is perceived by the human eye as haze. Condensation of vapor into droplets of water begins at a height of about 1.5−2 thousand meters. Steam is generated in very shallow still water droplets. However, the condensing has a side effect — heat. It heats the already formed droplets and causes them to evaporate again chaotic way. The more evaporation there is, the more steam which again goes up and again under the influence of heat, begins to evaporate. Layered a mist, olacapato: ru.wikipedia.org In the end, the top of Cumulus clouds is beautiful is constantly changing, but the very bottom of the cloud is clearly the "cut" ground level atmospheric pressure, which does not allow a couple to settle down the dew. Cumulus clouds are often very strongly swirl by the wind and create a very beautiful picture of the blue sky. Their movement is entirely dependent on the wind speed. But the higher Cumulus cloud, the faster the process of condensation of vapor into water drops. The cloud begins to darken and the white turns to dark grey and then to black. And this is the color of storm clouds. If the temperature difference at the surface and at the lower limit of the clouds is very dramatic, the growth process of the droplets is accelerated, is electrical breakdown (lightning), thunder and the downpour begins. Sometimes it is hail and strong squally gusts of wind.

Then again, they become layered, losing their Cumulus form. ...
