Tornado the successive disasters are killing thousands

 

Some latitude and longitude latitudes between latitudes 15 – 45 north and south of the equator are experiencing some of the most powerful and devastating hurricanes on their way, known as tornado

 

The source of the word tornado in Spanish means “revolves”, including the word ” Tornado ” means “thunder” and “thunderstorm”, and is called twister, and the words of some quarters by the name tornado

 

A tornado begins as a dark, funnel-like cloud that extends down a cloud of cumulonimbus. Tornado often generates giant thunderstorms called supercells, strong and steady storms. It consists of a warm, moist air rushing from the ground high to meet the colder, colder air. The moisture in it condenses to form a thundercloud, which in turn extends to a height of more than 50,000 feet. Variable winds feed at different levels of the atmosphere to give the tornado its characteristic repressive shape. The tornado rotates at a speed of up to 300 mph, with a diameter of several feet and one mile. Its trajectory can range from less than a mile to several hundred miles. The tornado moves and usually moves towards the northeast and in the direction of prevailing winds, – 60 miles/hour. How to be tornado can be summarized as follows

 

Tornado the successive disasters are killing thousands

Warm air rises to the top where the cold air is formed by the storm cloud

 

If the rising air collides with winds from two different directions – from the southeast at the ground level, and from the west at the upper level – the air will rotate like a tornado

 

Because of the speed of movement of the wind at the top, the air will pull up vertically and turn tornado quickly

 

The worm-induced funnel reaches the ground to become a tornado

 

the pressure in the center of the tornado is about 60-80% lower than usual, and the wind on its edges is very strong, doing something like a huge vacuum cleaner that sweeps everything

 

The conditions that lead to tornado occur mostly in the center and south of the United States, where warm, humid air comes from the Gulf of Mexico, colliding with dry cold air coming from the Rockies in the west and from Canada. The tornado zone extends between the Appalachian Mountains to the east and the Rocky Mountains to the west, And Nebraska to the north of the Gulf of Mexico to the south, as can occur in all US states, and other parts of the world, including the coast of the Gulf of Guinea in West Africa where the African tornado is called thunderstorms, rain and violent sudden and occur most of the day and cause heavy losses

 

Meteorologists can predict the possibility of bad weather before they occur about 12 – 48 hours, using information from aerial meteorological balloons, satellites and special radar called Doppler radar, and computers analyze information to identify and predict the occurrence of tornado strength, place and time

 

Although tornado can occur at any time of the year, it is common during the spring and early summer, the peak of which occurs in May and June in terms of frequency, and April appears to be the most prominent and most deadly cause

Scientists estimate the speed of tornado by estimating the damage and damage resulting from it, using the Fujita-Pearson scale developed by the Japanese American weather scientist Dr. Fujita in 1971 to determine the strength of the tornado of the losses and damage that it leaves, and did not receive wide acceptance at the time when it was first published, and two years after the publication of Fujita and Dr. Pearson research in which other factors added to the scale they named together, as follows

 

 

F0 – tornado Gale: The speed of the wind is 64 – 116 km / h, the damage is simple, damage chimneys, break tree branches, root out plants, and destroy billboards and signs

 

 

F1 – tornado Medium moderate: wind speed 117 – 180 km / h, medium damage, uprooting trees, an upper layer of roofs, windows were broken and cars out of roads

 

 

F2 – Tornado significant: The wind speed is 181-253 km / h, the damage is great, the roofs of houses are demolished, the houses are destroyed, the trees are crushed or uprooted, and the small things are pushed with tremendous force

 

 

F3 – tornado Severe: Wind speed 254 – 332 km / h, severe damage, moving and fluctuating ceilings and some walls of buildings with good construction, and most of the forest trees, and lift heavy cars and received away

 

 

F4 – tornado Destructive: wind speed 333 – 419 km / h, the damage is very severe, buildings with good construction are grounded, poorly constructed buildings flying for limited distances, cars flying, and large objects pushing with tremendous force

 

 

F5 – tornado Incredible / Incredible: The wind speed is 420 – 512 km / h, the damage is unbelievably huge, displaces the strong structures of the houses, snakes the foundations and travels over great distances and ripples. , Incredible phenomena occur

 

 

The difference between a tornado and harkens

The Harikin is a name called hurricane tornado in the West Indies, the Gulf of Mexico and the Florida American coasts. The Hareken starts with the trenches and ranges from 160 to 650 miles. The wind speed is around 120-200 km / h. , With a diameter of 8 – 24 km, and the land is subject to comprehensive destruction, and the sea is facing very high. The Harkins are therefore larger in size, with long distances. Tornado is smaller in size and reaches short distances and, fortunately, can be predicted

Water droplets clog through their height to form raindrops. The buoyancy capacity of air packs varies partly due to water and ice. When these beams reach the stratosphere, they lose their momentum and fall to an altitude of about eight miles. Evaporated water droplets evaporate out of the rising wind in the medium-altitude dry air on the northeastern side of the super cellular, cooling the air and landing it on the surface. Over time, the rain and the falling current are pulling in the direction of the rising tide. Because humidity in the cold air is higher than in warm air, it becomes cloudy at lower altitudes if forced to rise. Thus a low cloud forms when the rising current absorbs part of this air

Unlike most thunderstorms, which have several ascending and descending currents that overlap each other, the super cellular cells contain one or two cells, each of which has two currents, one of which is a downward current and the other is a broad upward current and dizziness. The high regulation of a super cellular cell allows for a long time to remain in a highly stable and highly efficient state, leading to the formation of a repressive cyclone. A rising current, with a radius of one mile to three miles, may start with winds of up to 50 mph or more, forming an average hurricane. The storm then evolved at a low altitude, and possibly also a repressive cyclone usually to the south-west side of the upward current near the nearby downward stream, while the average tornado may be either fully developed or gradually fading

 

Eventually, the average tornado fades in a rain cover, when its rising current near the surface of the earth passes very cold air flowing from the heart of the falling current. In superconducting cells, a new medium hurricane might have formed a few miles to the south-east of that fading, along with a front of the active wind, the boundary between the hot and cold air masses. A new tornado may then form quickly

Hurricane tornado is considered one of the most devastating storms. The area passes through looks like a violent earthquake. The tornado, the destructive speed of the wind, and the intensity of the atmospheric pressure are due to its large size. Most tornadoes are no more than two kilometers wide, while the atmospheric pressure drops to 800 or 600 mill bars and winds up to 500 km / h. In fact, the intensity of the atmospheric pressure gradient or the speed of the wind that accompanies the tornado has not yet been measured, since the monitoring equipment it is undergoing destroys it completely. But it has been estimated from the analysis of the effects it leaves on buildings and facilities and from some mathematical and abstract models. Most of the world where tornado occurs in the central and southeastern part of the United States, and rarely occurs north of latitude 45 north. It is very rare in other parts of the world except for Australia. It is similar to thunderstorms in that the preferred time of occurrence is between 2 pm and 9 pm, and more than 67% of tornado hurricanes that hit the US occurred at 2 pm and 8 pm. The tornado routes are usually random and chaotic, but it does not go very long, and most of its trails in the United States are only 20 kilometers long. It runs at a speed of 50-75km

Tornado is formed in the warm sector especially at the front of the cold front and runs parallel to that front and determines the location of the jet stream and its motion. And the best conditions are favorable to be when cool polar air crawls over humid tropical air coming from the Gulf of Mexico. The tornado tends to be in the sea and then to land. Many training modules designed to represent and analyze tornado, such as the Turner model, are still unable to fully explain the origins of the cyclone.

Typhoon tornado

Tornado-tornado is a violent windstorm characterized by swirling conical clouds, dense suppression and a cloud of rotten dust known as the tornado

The source of the word in Spanish means “revolves”, including the word means “Thunder” and “Thunderstorm”, and is called colloquial twister, and expressed by some quarters as a typhoon

 

Where they occur

In the mid-latitudes and latitudes between latitudes 15-45 north and south of the equator, such a tornado is known to occur

When the water temperature in the tropical seas rises to a temperature of 30-27 ° C, it warms the air layer adjacent to it. By heating it lowness the air pressure. It expands and rises to the top. A low-pressure zone is attracted to the wind from the surrounding high-pressure areas And it evaporates from each direction leading to the evaporation of water and the rise of this light steam up in the middle of the cold air and wind load and fill it any slow drive, and compose it and raise it up in a continuous process of continuous lead to increase the lift up, Of the water vapor that begins to condense and cool it The fact that it is cold water drops, and each of the granules of cold and ice crystals, and once the process of decomposition stops, the rain begins to precipitate

This precipitation may be accompanied by thunderstorms, thunderstorms, floods and cold and snow, and with more water vapor, a greater amount of heat is released, increasing the pressure of the air, encouraging more rain. Over the tropical seas, and by increasing their size are increasingly confined between cold areas of high pressure, which increases the chances of the formation of clouds and their formation and composition and thus increase the shipping of water vapor and the possibility of falling rain, That is, the infestations) and influenced by the rotation of the earth around its axis To the east in front of the sun, thunderstorms and telegraphs begin to rotate in the opposite direction of the clock in the northern hemisphere, and with the clock in the southern hemisphere, a high-speed windstorm known as tropical cyclones or tornado Tropical cyclone or Tropical Cyclone, and take the storm’s speed to 120 kilometers per hour, turning it into a real heart with a hot heart of hot air called the eye of the hurricane ranging from The wind speed is between zero and forty kilometers per hour And it revolves around the eye tornado swirls of thunderstorms associated with the destructive and formation of heavy clouds filled with water vapor and (clouds) and the formation of both cold and snow, precipitation Dumped and the occurrence of lightning and thunder

 

It is clear that heating the sea and ocean water plays a key role in the formation of both tornados. The climatic cycles of El-Nino, which warms the waters of the Pacific Ocean, and La Nina, which cool it, are also factors that play an important role in the process of becoming a tornado
