What are the conditions under which a tornado is likely to occur?

Tornadoes are likely to occur when a storm system drives a cool air mass and a dry air mass into a very warm, moist one, producing thunderstorms. A layer of stable air called a cap holds back storm development at first allowing instability to build, then the strongest storms break the cap and grow at explosive rates. They then encounter wind shear, where the wind speed increases and wind direction rotates counterclockwise (or clockwise in the southern hemisphere) with height. This sets the storms rotating. The rotation in these severe storms, called supercells, can then go on to produce tornadoes

What causes a tornado to turn vertical?
The tornado itself is vertical when it first forms. The rotation that forms it starts out as what is called horizontal vorticity. This vorticity can get caught in the updraft of a thunderstorm, tilting it into a vertical position. The new vertical rotation joins with the updraft to become a mesocyclone. Under the right conditions the mesocyclone can tighten and intensify to produce a tornado.
How are tornadoes predicted?
Forecasters use massive computer programs. Tornadoes form under certain conditions, and if forecasters see those certain conditions, they study the area more. However, these models cannot predict where a tornado will form, only regions where there is the potential for tornadoes. On the scale of individual storms scientists use Doppler radar to detect rotation within a storm. Depending on the signature this can either indicate the mesocyclone that produces a tornado, or the tornado itself.
What weather patterns are nessary for a tornado to occur?
Tornadoes require wind shear and thunderstorms (which can form under a number of circumstances) to occur. Typically the strong thunderstorms needed for tornadoes to occur form along a dry line or cold front. Tornadoes very often form where a cold front and dry line intersect.
What is issued when a tornado funnel clouds has actually been sighted or is indicated by radar?
Under these circumstances a tornado warning would be issued.
Why isn't it raining or storming during a tornado warning?
There are three possibilities. First is the tornadic thunderstorm may not have reached you yet, as tornado warnings are sometimes elongated along the storm's projected path. Second, you may be under a low precipitation supercell, which is a potentially tornadic storm that produces little or no rain. Third, you may be under the updraft part of the thunderstorm, which is often rain free and sometimes relatively calm. This is also the part of the storm where a tornado is most likely to form.
What happens after a tornado strikes in snow?
It would be highly unusual for a tornado to strike an area where there is snow on the ground. Tornadoes generally occur during periods of warm weather. If such an event were to occur it would be little different from a tornado striking under ordinary circumstances. The tornado would likely lift some snow into the air, but that would be of little to no consequence compared with the damage tornadoes usually inflict.
Under what conditions will rusting not occur?
Rust will not occur where it is dry and humid
How can you tell when a sandstorm will occur?
Dust storms are most likely to occur on hot summer days under certain atmospheric conditions, so meteorologists can frequently predict the possibility of these storms.
Under what conditions would no breeze occur?
bob
How do acids an bases affect a cells environment?
Many chemical reactions can only occur under acidic conditions and others can only occur under basic conditions.
What type of air pressure creates a tornado?
Tornadoes form under conditions of low pressure
How did Ada get put under tornado watch but then got put under tornado warning on March 26 2017?
A tornado watch means that general weather conditions are right for tornadoes to form in a region. On March 26, 2017 such conditions began to develop across much of Oklahoma and a portion of northern Texas. A tornado warning means that a tornado has been detected or a storm may produce one soon. A tornado warning was issued for Ada when a rotating thunderstorm capable of producing a tornado developed in the area. A possible tornado was later spotted with this storm.
Will there ever be a rainbow twister?
If by that you mean a tornado with a rainbow near it then yes, sometimes rain falls very near a tornado, which can form a rainbow under the right conditions
Fermentation reactions generally occur under conditions of?
Low Oxygen Concentration
What is a tornado and what makes it occur?
A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground, often made visible by a funnel or cone shaped cloud. A tornado occurs when rolling air called wind shear is turned vertical by a thunderstorm. This creates a supercell, a storm with a strong, rotating updraft called a mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, forcing the rotating into a tighter, more intense vortex: a tornado.
Was there any tornadoes in England?
Tornadoes can occur anywhere in the world, except Antarctica. The UK has seen its share of tornadoes, although most have been under the F1 damage level. Tornadoes are less likely in England, but are still possible. The largest tornado in England was probably the London Tornado of 1091. The death toll was unknown.
Under what conditions is yaws likely to occur?
Yaws tends to strike children, particularly between the ages of two and five. It is common in areas where poverty and overcrowding interfere with good hygiene practices.
