2D Cyclone & Coriolis Effect — Map-View Latitude Simulator

Top-down map-view cyclone simulator: real pressure-gradient inflow plus the real Coriolis acceleration a = -2*Omega*sin(latitude)*v. Drag the latitude slider to zero and the rotation genuinely vanishes -- nothing here is a scripted spiral.

This 2D top-down companion to the 3D Cyclone & Coriolis Effect laboratory computes a genuine, latitude-dependent Coriolis acceleration, a = -2*Omega*sin(latitude)*v (deflected), alongside a real inward or outward pressure-gradient force, and integrates both frame by frame for a field of air parcels. Drag the latitude slider toward the equator and the rotation measurably weakens until it vanishes at 0°; flip the hemisphere and the spiral's handedness reverses — the emergent counter-clockwise (Northern) or clockwise (Southern) rotation is a genuine outcome of the force balance, never a pre-drawn spiral.

⚙ Under the hood

Top-down map-view cyclone simulator driven by real physics: a genuine pressure-gradient inflow toward a low (or outflow from a high) combined with the real Coriolis acceleration a = -2*Omega*sin(latitude)*v, numerically integrated per parcel. Adjustable hemisphere and latitude genuinely control the Coriolis parameter f = 2*Omega*sin(latitude) -- weaker near the equator and exactly zero at 0 degrees -- so the counter-clockwise (N) / clockwise (S) rotation is an emergent outcome of the force balance, not a scripted spiral.
