Those ingredients include warm moisture near the surface and relatively cold, dry air above. But supercells require winds that increase in strength and change direction with height, generating horizontal tubes of rotating air parallel to the earth’s surface.
Warm air below a horizontal vortex rises “like a hot-air balloon,” says Brooks, and bends it into an arch. One of the two vertical vortices forming the arch then peters out. Shearing winds tilt the top of the surviving vortex, causing cool rain to fall away from the warm surface air fueling the newly born mesocyclone, letting the supercell purr like a finely tuned engine. (See an animation of how tornadoes form.)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
