Falling raindrops create ripple rings on puddles, dynamic clouds drift overhead and an optional rainbow appears. Four weather modes: light rain, storm, drizzle and sunny rain.
Particle system for raindrops with gravity. Ripple rings expand on impact using wave interference. Cloud layer uses Perlin noise for natural movement.
Switch between four weather modes. Watch ripple patterns form on puddle surfaces. The rainbow appears when sun angle and rain coexist.
Real raindrops are not teardrop-shaped — small ones are spherical, and large ones (>2mm) become flattened hamburger-buns due to air resistance. Very large drops break apart.
