Why is a tornado visible?
There are two components that make a tornado visible. The first is the condensation funnel or funnel cloud, which forms from moisture condensing inside the tornado. The other component is the debris cloud. This consists of dust and debris lifted into the air by the tornado's winds.
How was the Edmonton tornado first recgonised?
their was a man that was driving out side of edmonton. he saw the funnel cloud start to form and heard weather warnings on the radio so he phoned in to warn them that their was a tornado on its way to edmonton.
What happen to make tornadoes visible?
There are two main factors. First, moisture in the air condenses as a result of decompression inside a tornado, producing the visible funnel cloud. Second, a tornado's winds lift dirt and debris into the air, forming a debris cloud or dust whirl
Where do tornadoes get their color?
There are two main facotrs. First of all, there are often two visible components to a tornado: the condensation funnel and the dust cloud. The condensation funnel is made of water droplets just like an ordinary cloud. Like other clouds, the apparent color depends on the lighting conditions. It it is front lit it will appear light gray or white. If it is back lit it will likely appear dark gray or black. A tornado may also pick up significant amounts of soil, creating a dust whirl matching the soil color. This may be limited to the lower portion of the tornado, or may envelope the entire funnel. Tornadoes can take on other colors if they are hit by sunlight coming in at an angle.
How can a scientist predict when a tornado is going to happen?
In the first stage of tornado prediction scientists look for general weather conditions. The conditions include wind shear and systems that can form strong thunderstorms such as a cold front, dry line, or low pressure system.If such general conditions are in place a tornado watchis issued.The second stage scientists look for conditions that may soon produce a tornado, or if a tornado is forming. These include using Doppler radar to look for strong rotation in thunderstorms or possibly even the signature of an actual tornado. Storm spotter are also sent out to report strong rotation, funnel clouds, and tornadoes. If strong enough rotation is detected or if an actual tornado or funnel cloud is spotted or detected a tornado warning is issued.
What caused hailstone to fall after the first tornado?
it is that it is tornado alley it make a strong storm with ice and then ice comes then tornado
What comes first in a dictionary tornado or tornado alley?
Tornado would come first. If any term's beginning letters are the same as the whole spelling of another term, the shorter term will come first.
Why do tornadoes often look black or grey?
The visible funnel of a tornado is composed of water droplets like an ordinary cloud, and so usually is the same color as the clouds that it extends from. Not all tornadoes are gray, however. Depending on lighting some may appear white or black. Tornadoes can also be colored by soil that they lift and become gray, black, brown, tan, or even red.
Explain very briefly how a dark cloud becomes a tornado?
First, the storm itself has to be rotating. A downdraft from another part of the rotating air and tightens and intensifies it into a tornado.
Which is the first thing that happens when a tornado forms?
When a tornado forms, violent rotating winds reach ground level, often kicking up a cloud of dust in the process.
What happens during stage 1 of a tornado when it is called a supercell?
First of all, the tornado is not called a supercell in the initial phases. The supercell is the larger thunderstorm that produces the tornado; it is not the tornado itself. In a supercell there is a rotating area of low pressure, primarily within the updraft portion of the storm, called a mesocyclone. At the most intense portion of the mesocyclone there is a rotating, low-hanging cloud called a wall cloud. Conditions within the thunderstorm cause a portion of the mesocyclone to tighten and intensify, and the circulation of the tornado begins to develop and descend toward the ground from the wall cloud.
How does the anatomy of a cumulonimbus cloud help allow the formation of a tornado?
It's not so much the anatomy of the cloud itself, but that of the wind currents in and around it. First, the updraft of the storm must rotate, this rotation often producess a lowering of the cloud base called a wall cloud. Second, a downdraft must descend from the back of the storm, often producing a hole in the clouds. This downdraft allows the rotating updraft to produce a tornado.
