Well, you know, we have these gizmos in the sky, we call them satellites, and they carry cameras, so everybody can get pictures looking straight down. And then every airport in the world has whirlygigs that tell everybody how fast the wind is blowing. And every country has an army of people who measure all sorts of weather facts, stuff you never even heard of, and it is all available as public knowledge just so everybody can be sure that an airplane can or can not land at this or that airfield.
Water from the ocean’s surface continually evaporates and rises with the warm air to form clouds. When conditions are right, several updrafts of warm air may combine, producing a chimney effect. As the chimney continues to grow, it will start spinning due to the rotation of the earth. Air pressure at the chimney’s bottom drops rapidly, drawing in still more air and moisture from outside the rotating column. It is similar to when water is sucked in at the bottom of a sipping straw. The warm, humid air may rise to a height of thirty to thirty-five thousand feet, where it encounters a blanket of cold air. Then it spreads out; the moisture condenses and begins falling as rain, whirling faster and faster with the winds as the storm develops
