They are the the most violet wind source in the world. They need warm, moist air to form, like thunderstorms. Some of the tornadoes are formed by the dry lines that separate the warm and cold air masses. Another way that a tornado form is that there is warm rising air, and cool sinking air meeting it. These 2 air masses have to be moving at different speeds. That is how you get the spinning funnel cloud, that may be a tornado later. The clouds you will see are cumulonimbus and cumulonimbus. But a funnel cloud is only tornado if it touches the ground. That funnel cloud is made out of rotating air and water droplets. The sky may develop a greenish hue when a tornado is about to strike. Tornadoes may be a funnel, or slender and rope like. some can be smoky and churning. Usually a tornado starts off as a white or gray cloud but if it stays around for a while, the dirt and debris it sucks up eventually turns it into black one. Usually, a tornado’s color matches the color of the ground.
