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.
The first commercial syntheti c fiber was produced by Hilaire de Bernigaud, Count of Chardonnay (1839-1924) after 29 years of research, was patented in 1884, and manufactured by him in 1889. This cellulose-based fabric known as Chardonnay silk was pretty but very flammable, it was removed from the market.
