vampares Posted April 30, 2014 Posted April 30, 2014 (edited) The people have been urning for a pointed topic.A tornado is basically a circular wind. As wind spins around it is thrown outwards creating a vacuum. The vacuum pulls it inwards. It spins really fast. This is a suspected tornado.This is results of a tornado.This is a non-casualty of a tornado. This radar is not full size so the purple high points are hard to see. There is one in Michigan and one or two in North Carolina. The activity in North Carolina is where the discussion starts. This is a water vapor satellite image. Notice the bursting action in North Carolina. This is a signature characteristic of a locally generated tornado. The is further WV bursting at the Mississippi river delta. Tornadoes are classified as convective systems. Convective systems occur when gaseous water condenses into liquid form. To evaporate water, energy must be added. For example a pot of boiling water. When water condenses, the heat that evaporated the water is released to something from the water. It could be another cold drop of water or the air. Ideal gas law PV=nRT Increasing the temperature increases the volume because this is an open air system sort of. The air expanse but the mass remains the same. The lower density rises and this is due to pressure really. Because we are on the rise more water condenses which releases more heat energy. This situation could actually be reproduced with substances other than water. That is not to say meteorology is a sterile science. But the calculations yield very accurate data. The difficult faced is that this ordinarily occurs far above the ground. While internally a cloud may contain a vortex the vortex is not driven on the ground. Ground driven convection is actually rather cumbersome. It will struggle to yield any rain at all. Higher altitude convection can draw from the air below it. As air convects upward it leaves a vacancy. If the vacancy is filled by higher pressure air below it that air will condense water just as the air previous had at about the same pressure and altitude. And it will also move upwards and leave a vacancy. Edited April 30, 2014 by vampares

vampares Posted April 30, 2014 Author Posted April 30, 2014 (edited) We need more The KEY to tornado genesis is low pressure. Tornadoes move from low pressure to higher pressure. But not just low pressure. The low pressure has to be driven by something. It has to be maintained. The previous graphic also display the maintenance of low pressure which is about 1000 and over top of Iowa. High pressure air moves in the low pressure area. When it at low pressure it condenses water and convection begins. ! Moderator Note Does this have a point, or should I close it? Do you have nothing better to do with the time on earth God gave you?
