oalesce like liquid ones. Clearly then drops of that size were suspended in the air or else they could not have Miehet Nike Roshe Full Anti-Fur been so large when frozen.
Some think that the cause and origin of hail is this. The cloud is thrust Belstaff 2014 Nowy Kurtki up into the upper atmosphere, which is colder because the reflection of the sun’s rays from the earth ceases there, and upon its arrival there the water freezes. They think that this explains why hailstorms are commoner in summer and in warm countries; the heat is greater and it thrusts the clouds further up from the earth. But the fact is that hail does not occur at all at a great height: yet it ought to do so, on their theory, just as we see that snow falls most on high mountains. Again clouds have often been observed moving with a great noise close to the earth, terrifying those who heard and saw them as portents of some catastrophe. Sometimes, too, when such clouds have been seen, without any noise, there follows a violent hailstorm, and Classic Short Dylyn 1001202 the stones are of incredible size, and angular in shape. This shows that they have not been falling for long and Alex Burrows Jersey that they were frozen near to the earth, and not as that theory would have it. Moreover, where the hailstones are large, the cause of their freezing must be present in the highest degree: for hail Calle Jarnkrok Jersey is ice as every one can see. Now those hailstones are large which are angular in shape. And this shows that they froze close to the earth, for those that fall far are worn away by the length of their fall and become round and smaller in size.
It clearly follows that the congelation does not take place because the cloud is thrust up into the cold upper region.
Now CG Naiset Kensington Parka we see that warm and cold react upon one another by recoil. Hence in warm weather the lower parts of the earth are cold and in a frost they are warm. The same thing, we must suppose, happens in the air, so that in the warmer seasons the cold is concentrated by the surrounding heat and causes the cloud Johan Franzen Jersey to go over into water suddenly. (For this reason rain-drops are much Andreas Martinsen Jersey larger on warm days than in winter, and showers more violent. A shower is said to be more violent in proportion as the water comes down in a body, and this happens when the condensation takes place quickly,-though this is just the opposite of what Anaxagoras says. He says that this happens when the cloud has risen into the cold air; whereas we say that it happens when the cloud has descended into the warm air, and that the more the Nazem Kadri Jersey further the cloud has descended). But when the cold has been concentrated within still more by the outer heat, it freezes the water it has formed and there is hail. We get hail Nike Air Zoom Strong Damskie when the process of freezing is quicker than the descent of the water. For if the water falls in Nike Kyrie 3 a certain time and the cold is sufficient to freeze it in less, there is no difficulty about its having frozen in the air, provided that the freezing takes place in a shorter time than its CG Miehet Calgary Parka fall. The nearer to the earth, and the more suddenly, this process takes place, the more violent is the rain that results and the larger the raindrops and links:
