Once a hurricane moves over land, it loses its moisture supply so the air contains less moisture. Air must rise further before it reaches a temperature where it can no longer hold the level of water...

Air in a Northern Hemisphere hurricane circulates counterclockwise at tremendous speeds. As it spins, air also moves inwards, rises upwards and then moves outwards. The rising moist air condenses,...

Water issuing from an ordinary faucet tells a complex tale of its journey through a pipe. At high velocities, the faucet’s gushing stream is turbulent: chaotic, disorderly -- like the crash of ocean...

(Left: Flow in a pipe. At high velocities, the flow is turbulent, and at intermediate velocities, transitional. The transitional flow is a mix of eddying flows and laminar flows. The eddying flows...
