Tornadoes usually weaken if cold or dry air starts feeding into the updraft of the thunderstorm that drives the tornado. This causes the updraft, and thus the tornado, to lose power.
When a tornado begins to dissipate it usually shrinks. Usually this means a tornado is weakening , though some tornado intensify at this point. As the tornado continues to get smaller the funnel may becomes bent and elongated, giving it a rope like appearance. In fact, this process is called "roping out" As this happens the tornado will continues to shrink and weaken until it completely dissipates.
When a tornado hits the ground, it can cause significant destruction by uprooting trees, damaging buildings, and tossing debris into the air. The swirling winds can reach extreme speeds, creating a wide path of devastation in its wake.
In some cases one tornado will dissipate completely, and then a completely new tornado will form afterward from the same thunderstorm. This is called a tornado family.
The five stages of a tornado are 1. the whirl stage--when the cumulonimbus clouds begins being hit by winds blowing in different altitudes, and start rotating horizontally. this causes a funnel of air to form, otherwise known as a vortex, both whirling around and up. 2. the organizing stage--once the funnel touches the ground, it forms a solid base, and the upward, whirling motion sucks up debris into the funnel. this causes the tornado to darken. 3. the mature stage--this is the most destructive stage, where things are destroyed, as it is the most powerful. 4. the shrinking stage--when the tornado is dissipating, and weakens to the point where it is no longer visible, and slowly begins to die down. 5. the decaying stage--the tornado is completely gone.
What causes tornadoes to dissipate is not fully understood, but it is believed that cold thunderstorm outflow undercuts the parent circulation (mesocyclone) that drives the tornado, cutting of the warm air that drives the thunderstorm, causing it to weaken to the point that it can no longer sustain a tornado.
it stays on the ground until it weakens
The three steps of a tornado are formation, maturity, and dissipation. During the formation stage, a rotating column of air develops. In the maturity stage, the tornado reaches its maximum intensity, causing the most damage. Finally, during the dissipation stage, the tornado weakens and eventually ceases to exist.
A tornado can lose its strength when it moves over cooler water or land, or if it encounters strong winds that disrupt its circulation. Additionally, if the thunderstorm that spawned the tornado weakens or dissipates, the tornado will also lose strength.
The three stages of a tornado are the formation stage, the mature stage, and the decay stage. During the formation stage, a rotating updraft called a mesocyclone develops. In the mature stage, the tornado reaches its peak intensity and causes the most damage. Finally, in the decay stage, the tornado weakens and eventually dissipates.
After a tornado weakens and dissipates, the debris it picked up can fall back to the ground or be carried away by the wind. Items may be dropped back relatively close to where they were originally picked up or scattered over a wider area depending on the strength of the tornado.

A tornado may start dying due to a decrease in the warm, moist air feeding into the storm, or if it becomes wrapped in rain-cooled air that stifles its rotation. Additionally, if the parent thunderstorm that spawned the tornado weakens or moves away, the tornado may dissipate.

Tornadoes often go through a series of stages as they develop, strengthen, and dissipate, often with distinct appearances.The dust whirl stage: The ground-level circulation of the tornado is developingThe organizing stage: The tornado is on the ground and increasing in size and intensity.The mature stage: The tornado is at its largest and generally strongest point.The shrinking stage: The tornado begins to narrow and lose energy. Due to dynamic effects, some tornadoes intensify at this point.The rope-out stage: The tornado becomes very narrow and the funnel may bend and wind as the tornado weakens and eventually dissipates.
Tornadoes typically weaken when they lose their source of warm, moist air that fuels their intensity. This can happen when a tornado moves into a cooler or drier environment, or when the storm system that spawned the tornado weakens. Tornadoes can also weaken as they interact with friction from the earth's surface or from encountering other weather phenomena.
