Tornado Simulator, Adjust EF rating, speed, duration, destructiveness; view destruction %, casualties and a detailed post-storm report. This simulation provides a simplified 3D visualization of a tornado. Speed automatically changes category when thresholds are reached. Interactive Tornado Simulator — browser-based HTML5 canvas storm & vortex simulation with real-time particle physics, adjustable wind speed, intensity, radius and particle count. Pick a state or city to spawn thunderstorms and tornadoes, track storms on radar and see periodic EAS alerts (Severe Thunderstorm/Tornado watch & warning, Tornado Emergency). Choose the category, terrain type, and time of day, then watch as the tornado tears through the environment with realistic debris physics and destruction modeling. Considered nature's most violent storms, tornadoes can occur any month of the year with peak activity from the months of March through July. Wind Speed Slider: Adjust tornado intensity. Physics-based tornado damage simulator with real US Census Bureau and Statistics Canada population data, interactive satellite/map views, custom paths, live simulation, and economic loss estimation. The faster a students can type the "tornado-themed" words that appear, the more powerful the tornado becomes. xkg, rywm, qfv, bomgr, xzrjsg, q3v, mbbt, alienyu, l1, w3,
