A tornado is defined as a strong rotating air column with vertical axis, which must have contact to the ground. In most cases a tornado is visible as a funnel cloud.
Magmatic gases hold the main responsibility for magma production at great depths in the Earth's mantle. Furthermore, they are the predominant driving forces of volcanic eruptions.
