## 概述

Interactive visualization of Coriolis force demonstrating Earth's rotation effects on moving objects, projectile deflection, Foucault pendulum precession, and atmospheric circulation patterns. Features the fundamental equations: Coriolis force F_cor = -2mΩ × v showing cross product of angular velocity and velocity vectors, horizontal acceleration a_cor = 2Ωv sin(λ) with latitude dependence, Foucault pendulum period T = 24h/sin(λ) for precession rate, Earth's angular velocity Ω = 7.292 × 10⁻⁵ rad/s. Real-time visualization includes: (1) Earth view canvas showing rotating sphere with latitude/longitude grid lines, current latitude marker with animated position, rotation axis indicator, hemisphere labels (N/S), real-time rotation angle display showing Earth's spin; (2) Projectile trajectory view with dual reference frame comparison: inertial path (straight blue dashed line) vs rotating frame path (red curved line showing Coriolis deflection), velocity vector arrows (orange) showing initial direction, Coriolis force vectors (purple dashed) perpendicular to velocity, dynamic projectile position with trail visualization, deflection magnitude display updated in real-time; (3) Foucault pendulum demonstration showing pendulum bob oscillation, precessing swing plane tracing rosette pattern on floor (demonstrating Earth's rotation beneath), support point and string visualization, reference circle showing original swing direction, directional markers (N/E/S/W), accumulated precession angle display, theoretical vs actual precession comparison; (4) Atmospheric circulation panel showing cyclone (low pressure L) with inward spiraling flow (counterclockwise in Northern Hemisphere) and anticyclone (high pressure H) with outward spiraling flow (clockwise in Northern Hemisphere), particle animations demonstrating flow directions, hemisphere-dependent rotation direction (reversed in Southern Hemisphere), realistic spiral arm patterns with speed variations. Interactive parameters: latitude λ (-90° to +90°) with hemisphere auto-detection, Earth rotation speed multiplier (0.1-10x for visualization), projectile velocity v (10-500 m/s), launch direction (0-360°), flight time (1-100 s), animation speed control (0.1-5x). Quick presets: Mid-Latitude (45°, moderate deflection), Polar Region (80°, maximum Coriolis effect), Equatorial (0°, zero deflection), Long-Range Artillery (high velocity, extended flight time). Display options: toggle Earth grid overlay, velocity vectors, Coriolis force vectors, inertial reference frame path visualization. Educational content covers Coriolis force physics (rotating reference frame origin, angular momentum conservation, latitude dependence: sin(λ)=0 at equator, sin(λ)=±1 at poles, velocity dependence: faster objects deflect more), Foucault pendulum mechanics (plane precession demonstrating Earth's rotation, period formula T = 24h/sin(λ), 24h at poles, 33.9h at 45°, infinite at equator), atmospheric and oceanographic effects (cyclones/anticyclones rotation directions, trade winds deflection, ocean current gyres, jet stream patterns), practical applications (long-range artillery correction, aviation navigation calculations, meteorological weather prediction models, space launch site selection - equatorial launches get velocity boost), common misconceptions (toilet flush direction dominated by basin shape not Coriolis, sniper shots only affected at extreme ranges >1km, deflection varies with conditions not constant), and historical context (Gaspard-Gustave de Coriolis 1835 mathematical derivation, Léon Foucault 1851 pendulum demonstration, first practical use in artillery ballistics, fundamental to modern meteorology and oceanography). Multi-language support (zh, en, de, fr, es, pt, ru).
