There is no given humidity level, but it is usually pretty humid, as tornadoes depend on thunderstorms, which are powered by warm, moist air.
Yes. There is moisture in a tornado. The air a tornado pulls in has been moistened by rain. This moisture condenses to form the visible funnel cloud.
A tornado is made up of violently rotating air. It often contains moisture that has condensed as well as dust and sometimes debris that the tornado has picked up.
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..
A tornado pulls in air that has become moist due mostly to rainfall. The rapid pressure drop inside the tornado cools the air, causing the moisture to condense and form a funnel shaped cloud.
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.
Wind direction is the direction which the wind blows. If the wind direction is coming from an arid region, such as a desert, the air will be dry and moisture content will be low. If the wind direction is coming from an ocean, lake, or tropical area, the air will have a higher moisture content.
You cannot see the air itself, but you can see things that are in the air. The funnel itself is condensation. It consists of tiny droplets of water just like an ordinary cloud. Air entering tornado undergoes a rapid pressure drop which in turn causes a temperature drop. Since the air flowing into a tornado is usually moist, this causes the moisture to condense. Tornadoes can also lift significant amounts of soil and occasionally larger debris into the air, forming a debris cloud which can sometimes engulf the funnel.
Tornadoes do not contain moisture themselves, but they form due to the presence of moist air in the atmosphere. The moisture in the air plays a role in the formation and intensity of tornadoes by providing the necessary energy and instability for severe weather to develop.
The funnel of a tornado is condensation, similar to an ordinary cloud. The pressure inside a tornado is quite low. Air that enters a tornado is decompressed and cools as a result. In most cases that air is also rather moist, and the moisture condenses as a result of the cooling. Tornadoes are also made visible by the dust and debris that they pick up.
The funnel of a tornado is formed by moisture in the air that is cooled and condensed by the tornado's low pressure. Temperatures at higher altitudes are generally cooler, making it easier for the moisture to condense, which makes for a funnel that is wider at the top.
Weight is not something that is measure in a tornado. Even then, the size of a tornado, and therefore the amount of air it contains, varies widely.
How a tornado ends is not fully understood. It is thought, however, that cold air coming out of a thunderstorm (called outflow) undercuts the mesocyclone, the rotating updraft that drives the tornado. This chokes off the supply of warm air that feeds the updraft.
