Why are tornadoes so difficult to predict?
We do not know everything about the weather. We do however know how most weather-formations build up. This is also true for the conditions causing tornadoes. The problem involves accurate predictions as in the actual weather forecasts.
We can predict tornadoes by watching the skies. This can be done by satellite's, by radar, from ground, or a combination. This is all adding accuracy to the predictions.
The biggest problems of accurate weather forecasts is the amount of data needed to be calculated in order to provide predictions. We know to a certain extent how to use the data in calculations but this is still an inaccurate science at best. Some even believe that a butterfly flapping its wings at the wrong place at the right time can influence the weather on the opposite side of our globe.
The smallest changes in weather one place can change the outcome another place. We live on a living planet and as of that we simply have to accept certain conditions.
As we make weather models to support the globe as it is today, these models may have to be changed in the future as we change our globe due to deforestation and building dams, cities etc.
The most advanced models of our world today are able to predict weather up to 30 days forward. Not to a great accuracy as for which specific day and time it will start to rain, but within a few days. This sort of predictions is used in Shipping and Oil industry.
As of being able to actually calculate (I would rather use that word than "predict", because it all boils down to calculations). We can not "predict" a certain weather or a certain condition only for a small geographic area. This add uncertainty to predictions. The tornado touching down may be 3-10 miles away from where it was thought to be.
The amount of data needed for exact predictions/calculations are simply not available or possible to collect. To illustrate this further, consider the network of measuring-stations on ground. We can improve this network by placing one station for every 100 Square meters. This could be a kind of "back bone" in a new statistical model. Even so, with such a network, we would not be able to calculate proper predictions.
Reasons: The lower atmosphere tell one story, but is dependent upon higher altitude atmospheric conditions. Let's say we one day manage to measure (I don't know how, just lets say it is possible) the atmospheric conditions for every 100 meter up into the outer edge of our atmosphere.If we had all this statistical information readily available, then all we need to do is to put this into a statistical model, and we would have a really great tool.But even so!We need to be able to calculate accurately, and we can add much more information into this statistical model.We need to know the position of the moon and its distance from earth at all times. We need to know the position of all the other planets in order to calculate gravitational fields. Ultimately, we need to use all this information in combination with data from the sun. Is there going to be a solar flare? will the solar flare be directed so that it will be caught up in gravitational fields and be led towards earth in part or in full.It may sound like science fiction, but everything is calculateable if we have the power to do it and the knowledge as in how to do it.The amount of data needed for accurate calculations is immense. I do however beleive that it can be done.
One method could be to force an issue to the producers of mobile phones and computer equipment. Governments could force measurement-capability into all units, and the units could send data of measurement every time the measurements change. This would be able to provide very localized data for most of the globe where people are. It would still not be enough though.
What is the temperature during a tornado?
The typical temperature during a tornado can vary, depending on the temperature of the air inside the tornado. There have been temperatures recorded as low as 50 degrees and as high as 103 degrees.
If you are religious you might say God makes tornadoes.
However, from a scientific standpoint the answer is nobody. Tornadoes are a natural phenomenon that result from a certain set of weather conditions, not the actions of any person or persons.
Tornadoes do not exactly split. Some tornadoes have more than one vortex within the main circulation. In most cases these vortices are hidden inside the funnel, but if conditions are right they can become visible, resulting in a tornado with multiple funnels. The appearance of these vortices or the visual effect of one coming out from behind another can sometimes make it look like a tornado is splitting.
Does the rainbow touch the ground?
A rainbow is a trick of the light and has no physical properties. The water drops that cause the light to show up as a rainbow can come down and touch the ground, so a rainbow can look like it is touching the ground around waterfalls and similar water features, and is so high up in the air that it appears to touch the horizon. But the rainbow will move as the observer's eyes move, so you can never get to the rainbow, but it may appear to someone else that you have reached the end of the rainbow.
If you were in a plane looking down on a rainbow you would see a complete circle. From below we only see part of it because of the Earth's curve etc. And as described above only you can see the particular rainbow that you are seeing. It looks different to anyone else because of the way the millions of raindrops reflect light individually and so differ even to someone next to you.
Most tornadoes form in thunderstorms. When the cT and cP air masses meet they create instability in the atmosphere. As the cT air mass start to go up the cP air mass (basically the air) within the updraft tilts the circulating air from horizontal to vertical. The area of the rotation can be 2-6 miles wide and can extend through out the storm.
Can tornadoes join and then split in two?
YES. it is possible, however it is very unlikely. Tornadoes are a rare phonemon and if you are lucky to see one join, you are lucky. The possibility is very slim that you will ever see it split back up.
Does a hurricane or tornado cover more ground surface?
A hurricane typically covers a larger ground surface area than a tornado. Hurricanes are large, swirling storms that can span hundreds of miles and affect large portions of coastal regions, while tornadoes are smaller, more localized funnel clouds that typically cover a few miles at most.

Why do tornadoes form mostly in the Great Plains state?
The Great Plains are where cool, dry air meets warm, moist air This triggers the formation of thunderstorms that then interact with wind shear, which is also common in that region, to start rotating. The rotation within these storms can then produce a tornado.
Another factor on the Great Plain is something called a cap. The cap only lets the strongest storms develop so that they don't have to compete with weaker storms for energy. This allows them to grow even stronger.
The Great Plains see a high frequency of tornadoes because of their ideal climatic setup. In the spring storm systems cause warm, moist air from the Gulf of Mexico to collide with cool air from Canada and dry air from the Rockies, resulting in the formation of strong thunderstorms. About a mile off the ground a layer of stable air holds thunderstorm activity back, allowing instability to build underneath it. As a result when the storm break through the cap the instability will be enormous, leading to explosively powerful thunderstorms. At the same time wind speed and direction varies with altitude, which sets these storms rotating and also strengthens the updraft. This rotation combined with strong thunderstorm updrafts can then produce tornadoes.
How would you describe a tornado?
A tornado is a violently rotating column of air extending from the base of a thunderstorm to the groun,d often made visible by a funnel or cone shaped cloud. Tornadoes are capable of causing very severe damage.
Yes.The last tornado most powerful hit the town of Duduza in 2011, it was a EF3 tornado that kill 1 person and wounded 166 people.
In November 14,2008 a tornado hit the town of Molweni killing 8 people.Maybe this tornado reached the EF4 rank whit brick houses levelled on a path long 10 km.
An F4 tornado in January 18, 1999 killed 25 people and wounded 500 on a path of 120 km. This was the tornado with more victims in South Africa.
Who would win in a war between Russia and the US?
To the moron who wrote "USA has most advanced army and a jet that can go 12,000 miles and hour" your just a typical hypocrite and are a waste to forums like this so shut your facist trap.
First of all America and Russia both have advanced weapons and fighter jets. Russia holds the worlds most nukes and Russia has the worlds largest landmass.
USA has more people than Russia and has a more advanced military than Russia . USA has a higher population that Russia.
At the moment it would be a tie since USA could never take over Russias landmass and Russia could never reach all their army to USA. It would end up in nukes.
What are the differences between hurricane and tornado?
A hurricane is a tropical cyclone with sustained winds of at least 74 mph. Characteristics.
- A hurricane is its own, self-sustaining storm system.
- Hurricanes are enormous, typically spanning several hundred miles in diameter.
- Hurricanes form over warm ocean water and are mostly limited to the tropics.
- Hurricanes produce heavy rain and flooding in addition to powerful winds
A tornado is a violently rotating column of air extending fro the base of a thunderstorm to the ground. Characteristics of tornadoes that are not like those of hurricanes:
- A tornado is dependent on a larger parent thunderstorm
- Tornadoes are small in weather terms, only a handful have been over 2 miles wide.
- Tornadoes typically form over land and can form almost anywhere, but are most common intemperate regions
- Tornadoes a chiefly a wind event.
- Tornadoes are usually made visible by a condensation funnel.
How does a tornado have an impact on land forms?
Tornadoes can impact land forms by causing erosion, altering landscapes, and changing the physical characteristics of the affected area. The strong winds and intense force of a tornado can flatten buildings, uproot trees, and reshape the terrain through the deposition and removal of debris.
How do you categorize the tornado as weather related geologic in nature or caused by humans?
A tornado is categorized as a weather-related event because it is a natural atmospheric phenomenon caused by the interaction of air masses with different temperatures and humidity levels. Tornadoes are not caused by human activities but are a result of the Earth's weather patterns and atmospheric conditions.
Which much of the Great Plains is bare and?
Much of the Great Plains is covered in grasslands with minimal tree cover, making it appear bare in comparison to heavily forested regions. The semi-arid climate of the Great Plains limits tree growth, allowing predominantly grasses to thrive.
What causes most of the damage associated with tornado?
Wind causes most of the damage associated with tornadoes. In rare cases, tornadic winds can reach over 300 mph.
What is a destructive rotating storm in a shape of inverted funnel?
It is a tornado BUT it is funnel shaped NOT an "inverted funnel"
The other rotating destructive wind phenomena is not part of a storm (they usually happen on clear, hot days) and is called a whirlwind.
What The earth scientist most likely study tornadoes and cyclones is an?
Because they are natural phenomena that directly impact the Earth's atmosphere, weather patterns, and climate. Studying tornadoes and cyclones helps scientists understand how they form, develop, and interact with the environment, which can lead to more accurate predictions and better preparation for these extreme events.
Why is the great plains good for coal?
The Great Plains are suitable for coal mining due to the presence of large coal deposits within the region. The flat terrain and geology of the Great Plains make it easier to extract coal using surface mining techniques, such as strip mining. Additionally, the availability of transportation infrastructure, such as railroads, makes it convenient to transport coal to other regions.
What effect does tornadoes have on the geosphere?
Tornadoes have little effect on the geosphere. They can cause erosion and, in rare cases, scouring of the soil and they can uproot trees, which can increase erosion.
What of following causes tornadoes?
Tornadoes are typically caused by the collision of warm, moist air with cold, dry air, resulting in a rotating column of air extending from a thunderstorm to the ground. Other factors like wind patterns and geography can also influence the formation of tornadoes.
