Moist air contains large amounts of water vapor. Water vapor carries large amounts of energy. This energy is what powers a thunderstorm that might produce a tornado
The visible funnel of a tornado is the result of moist air being pulled into the vortex. The low pressure in the tornado causes a temperature drop, which in turn causes the moisture to condense. Temperature continues to drop as the air rises in the tornado, causing more moisture to condense at higher altitudes..
No single air mass "causes" tornadoes. This is Tornadoes form within thunderstorms. Thunderstorms form best when there is plentiful warm, moist air. So, a arm, moist air mass is usually present. Significant tornado activity, however, usually results from the thunderstorms that form near the boundaries between air masses. Usually where a warm, moist air mass meets a cooler or drier air mass.
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.
The warm moist air usually originates from a tropical body of water. The body of water depends on the tornado forming region. For the United States it is usually the Gulf of Mexico.
The fuel of a tornado is the warm, moist air that powers its parent thunderstorm.
A tornado's funnel cloud forms when warm, moist air rises rapidly and creates a rotating column of air. This spinning motion causes the air to condense into a funnel shape, which is visible as the iconic tornado funnel cloud.
A tornado forms when warm, moist air meets cold, dry air, creating unstable atmospheric conditions. This can lead to the formation of a rotating column of air, which extends from a thunderstorm cloud to the ground. The spinning motion causes the tornado to touch down and move across the landscape with destructive force.
A tornado forms when warm, moist air meets cool, dry air, creating instability in the atmosphere. This causes the air to rotate and form a spinning column of air. If the conditions are right, the spinning column can grow into a tornado, with strong winds and a funnel-shaped cloud.

Generally the air is moist as tornadoes require thunderstorms to form.
A tornado is poweered by the thunderstorm that porduces it. This storm is fueled by warm, moist air.

The Gulf of Mexico supplies most of the warm, moist air.

Air rushes into a tornado due to the low pressure at the center of the vortex, which creates a pressure gradient that pulls surrounding air inward. As the warm, moist air converges towards the tornado, it begins to spin due to the Earth's rotation and the updraft created by the storm, eventually forming the tornado.
Tornadoes are caused by the collision of warm, moist air with cold, dry air in the atmosphere, creating instability and strong updrafts. As the winds change direction and speed with height, it creates a rotating column of air. If this column of air tightens and intensifies, a tornado can form.
