High-resolution atmospheric modeling reveals the critical uncertainty that wind introduces into predicting meteorite fall locations.

The Freo Doctor—Perth’s cool breeze—rules the hunt for meteorites. Wind displaces space rocks hundreds of meters from the predicted point: a 10-gram fragment can land in an unexpected place, and only precise calculation of air currents can find it. Simulating 1107 atmospheric scenarios has already led to 12 recoveries. Perhaps future meteorite searches will rival the pinpoint accuracy of Mars rover landings. Meanwhile, every recovered meteorite is a message from the era when the Solar System was just being born.

🎯 The name 'Freo Doctor' is borrowed from the cool breeze that brings daily relief to the residents of Perth, Australia. So it is with meteorite hunting: correctly accounting for wind can be a lifeline, while ignoring it is a sure path to fruitless searches.
