How do air parcels respond to a horizontal air pressure gradient? A horizontal pressure gradient refers to air pressure changes along a surface of constant altitude. The horizontal wind is governed by interactions of the pressure gradient force, centripetal force, Coriolis Effect, friction, and gravity. The pressure gradient force initiates air motion and arises in part from spatial variations in air temperature and, to a lesser extent, water vapor concentration.
Carbon fiber was invented in 1958 by Roger Bacon. It used Rayon  fibers which where heated until carbonized to create a highly  durable and strong material.
Acetate Fabric and Viscose Fabric Information. Acetate was one of the first man-made fibers, developed by Doctors Camille and Henri Dreyfus, two Swiss brother based in Basel, Switzerland. Initially focusing on cellulose acetate for use in motion picture film, the brothers developed a workable fiber in 1913.
