Airienteering with 13MIKE

You encounter clear air turbulence, a microburst, and a lost Arizona dust devil in one fell swoop! You drop like a rock and manage to plunk down on top of a twin hi-rise complex!

“For those of you non-desert dwellers, who miss out on the beauty and sights of horny toads, lizards, antelope loose on the prairie, roadrunners, cactus, virga precipitation - let me educate you about dust devils! When a layer of air near the ground becomes overheated, it can rise and become a whirling column of air. Deserts see these mostly because the sun heats the air near the dry ground to a high temperature. It's easily seen and felt at my house in Prescott because it can carry sand and dust 1,000 feet or more above the earth!”
