The sinking air can create areas of high pressure at the Earth’s surface. When high pressure is in control, the air sinks. Sinking air compresses the atmosphere and inhibits clouds to form.

This paper presents a method for estimating the air data parameters for a small fixed-wing, unmanned aerial vehicle (UAV) using an arrangement of low-cost Micro-electromechinal systems (MEMS)-based ...
