What ingredients are necessary to form a tornado?

Answer 1

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

Answer 2

Thunderstorms can only develop when certain conditions pertain.

-Unstable atmospheric conditions (The environmental lapse rate (ELR) is greater than the SALR(saturated adiabatic lapse rate) through a depth of 10,000 feet and extending several thousands feet above the freezing level.

-Moisture (There is sufficient water vapour to form and maintain cloud and to provide early saturation so that instability occurs rapidly)

-Trigger action (There is a trigger or a lifting action)

Answer 3

Three things needed for a tornado to form are instability to provide the energy for thunderstorms, some sort of lifting mechanism to trigger those storms, and wind shear to set those storms rotating.

Answer 4

The two ingredients necessary to create a tornado are air instability and wind shear. Instability refers to the presence of hot air near the Earth's surface and cool air aloft, and wind shear refers to the weather phenomenon that exists when wind speed increases with height and direction changes with height. The instabi;lity powers thunderstorms while the wind shear gives these storms that rotation they need to produce tornadoes.

Answer 5

Usually a collision of warm moist air with cooler and/or drier air is neeeded to create thunderstorms. A third condition called wind shear is needed for them to produce tornadoes.

Answer 6

Three things needed to produce a tornado are an unstable atmosphere, wind shear, and twisting int the atmosphere.

Answer 7

they need warm water of at least 80º Fahrenheit,high humidity with moist air, light winds, and very warm surface temperatures.

Answer 8

Warm Air

Cold Air
