There are somewhat different sets of conditions for each of them.
Thunderstorms require an unstable atmosphere. This instability occurs when, if you lift a parcel of air from near the ground, it will become warmer than its surroundings and continue to rise. This generally occurs when the air near the ground is warm and moist. Greater instability generally means stronger thunderstorms. You also need some sort of lifting mechanism to start the air rising. This lifting mechanism can come in the form of a frontal system (cold front, warm front, or dry line), a land or sea breeze, a mountain blocking the wind, a low pressure area, and even the gust front of another thunderstorm. Regardless of the trigger, as the air rises, it cools. Moisture in the air condenses, forming clouds and rain and releasing heat, keeping the air warmer than its surroundings. This causes the air to rise even higher, forming a towering cumulonimbus cloud. Collisions of water droplets and ice crystals in the cloud generate lighting, which in turn produces thunder.
So, in summary, thunderstorms need:
- Warm, Moist air
- An unstable atmosphere
- A lifting mechanism
The formation of hurricanes and tornadoes both stem from thunderstorms, but follow different roots.
Hurricanes usually start off as tropical disturbances. These are disorganized low-pressure areas that produce showers and thunderstorms. When one of these disturbances moves over warm ocean water, the plentiful warm, moist air fuels the storms, causing them to strengthen. The strengthening updrafts or upward-moving air currents of the thunderstorms lowers the pressure in the disturbance, causing it to pull in more warm, moist air, further strengthening the system. As this happens, the Coriolis effect, a consequence of Earth's spin, causes the system to begin rotating. If wind shear is not too strong, this will cause the system to organize, allowing it to draw in air more effeciently. From here, the system will continue to organize until it becomes a hurricane.
So, in short, hurricanes need
- An initial area of low pressure and storms (disturbance)
- Warm ocean water
- Plentiful warm, moist air
- Coriolis force
- Little to no wind shear
Tornadoes typically form from a kind of powerful, rotating thunderstorm called a supercell, though they can also form from rotation in squall lines and sometimes other thunderstorm varieties. These storms typically occur near fronts in the middle latitudes, where large temperature contrasts and strong upper level winds can lead to very intense thunderstorms. At this point, strong wind shear, or differences in wind speed and direction with altitude, sets the storms rotating and alters the circulation, making them more efficient. In a supercell, and area of rotation and low pressure, called a mesocyclone, develops in the updraft. If conditions are right, a downdraft can wrap around the mesocyclone, tightening and intensifying it and bringing the rotation to the ground, forming a tornado.
So, in short, tornadoes need.
- Strong upper-level winds
- Strong wind shear
- Strong, rotating thunderstorms
- A downdraft in the right place within the thunderstorm
What else can I help you with?
Can a tornado form without a thunderstorm?
No, tornadoes typically form within severe thunderstorms that have strong updrafts and rotating air. The intense vertical motion within a thunderstorm is necessary for creating the conditions that can lead to tornado formation.
Which continent never had tornado?
Over time most places on earth experience tornadoes. However for a long time Antarctica has ntmoved from the south pole and being there, it may be that there has not been enough localized heat to form a tornado. However it would be difficult to prove this.
What elements need a tornado to be created?
For a tornado to form, you need three main ingredients: warm, moist air close to the ground; cooler, drier air above it; and strong wind shear (a change in wind speed or direction with altitude). These conditions create a rotating updraft that can develop into a tornado under the right circumstances.
Do tornadoes form from thunderstorms?
Yes, tornadoes typically form from severe thunderstorms known as supercells. These supercells have rotating updrafts that can create the necessary conditions for a tornado to develop. The interaction of different air masses within a thunderstorm can lead to the formation of a rotating column of air, which may eventually touch down as a tornado.
Where is a tornado likely to form?
Tornadoes most frequently happen in Tornado Alley, a strip of land that goes up the United States Midwest. However, tornadoes can happen almost anywhere. Flat land, like in Tornado Alley, does not interfere with the winds, so the tornado is not dissipated.
What are the basic ingredients needed for a tornado to form?
The basic ingredients needed for tornadoes are:Instability, which is needed for thunderstorms to form.A lifting mechanism to trigger storm development, usually in the form of a cold front.Wind shear, which sets the thunderstorm rotating.One the storm develops and has a well-defined rotation you need a downdraft to turn the rotation into a tornado.
Can a tornado form without a thunderstorm?
No, tornadoes typically form within severe thunderstorms that have strong updrafts and rotating air. The intense vertical motion within a thunderstorm is necessary for creating the conditions that can lead to tornado formation.
A tornado warning means that a tornado is likely to form?
Partially. A tornado warning means that a tornado is likely to form or already has formed.
Which continent never had tornado?
Over time most places on earth experience tornadoes. However for a long time Antarctica has ntmoved from the south pole and being there, it may be that there has not been enough localized heat to form a tornado. However it would be difficult to prove this.
Can a tornado form in England?
well i think a tornado can form anywhere
Is it true that a tornado warning means that a tornado might form?
No. A tornado warning means that a tornado is likely to form or has already been spotted.
What is a fire tornado?
a tornado in the form of fire
What is an electric tornado and how do they form?
There is no such thing as an electric tornado.
What is a wild fire tornado?
a tornado in the form of fire
Why tornadoes form in tornado alley?
They form in Tornado Alley for a couple of reasons. One of them is because of the weather. It is humid there. But, tornadoes can also form outside of Tornado Alley. They can form anymore!
Is a tornado watch better than a tornado warning?
Yes. A tornado watch simply means that general conditions are favorable for tornadoes to form. A tornado warning means that a tornado has been detected or may form at any moment.
Can a thunderstorm cause a tornado?
Yes, a severe thunderstorm can create the conditions necessary for a tornado to form. Thunderstorms with strong updrafts and rotation can produce tornadoes when other factors align, such as atmospheric instability and wind shear.
