Weather Arabs - may respond sometimes given news is a super torrent cloud (cloud hacks) in one of the countries and states, usually the associated said that the cloud of destruction material damage due to extreme weather phenomena that accompany these types of clouds, what is the cloud and how it is formed through the report the following.
Super torrent cloud or the so - called cloud hacks (super cell), is one of extreme weather occurring around the world, and consists of this kind of clouds are usually in very special circumstances, they need considerable moisture in the upper layers of the atmosphere and two types of air currents, "cold air And "warm and moist air" and these clouds form in the supratropical regions to increase the chances of meeting these types of winds, which results in the formation of this type of cloud cells.
This cloud begins to form at the meeting of a cold depression with moist air currents coming from the tropics.
This collision results in a process of air escalation, where the lighter warm air rises above the heavier cold air and creates the cooler air in the layers of the atmosphere before descending. the upper atmosphere , which carries with it a large amount of atoms of the water to the top , but the escalation of the air in those types of clouds will be an escalation of the roundabout (ie that the air is about partly because of the temperature difference which gives the cloud its distinctive shape).
The water droplets keep condensing in a short time due to the intensity of the air temperature difference until they freeze and become giant, giving the cloud its dark black color.
It consists pulled low , known as (shelf cloud) because of the cold air that moves down and then begin the cloud mostly due to the rotation and extreme low pressure composition of the center revolve around him and often come down from the center tornado very low pressure carrying winds Asmh b (tornado) may The wind speed reaches about 500 kilometers per hour and the pressure reaches 100 millibars, which is a very low pressure enough to suck the asphalt from the street.
This cloud is also accompanied by a heavy shower of very giant hail, some of which reach 7 centimeters in diameter, the size of oranges, and is also accompanied by heavy rain and deadly lightning, and these clouds cut very large areas according to the longevity of the cold depression and the size of its cold forehead.
As a result of the severe weather phenomena accompanying this type of clouds represented by heavy rain, strong thunderstorms and heavy showers of hail, it leads to the formation of torrents and floods that leave material and possibly human losses, and many other damages so that their damages may Affects crops and livestock.
Perhaps one of the world 's most active in the formation of the cloud hacks Super torrent are Argentina, southern Brazil and Uruguay , and in the Great Plains in the United States of America, and in the tropics, but that does not mean not to form this kind of clouds in the rest of the world, it is a kind of clouds Many times, even in the Arab world, such as Egypt, Saudi Arabia, the Maghreb countries, and most recently in Palestine.
