High-pressure area of their associated cold fronts. The stronger the pressure difference, or pressure gradient, between a high-pressure system and a low-pressure system, the stronger the wind. The coriolis force caused by the Earth's rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the wind moves outward and is deflected left from the center of high pressure). Friction with land slows down the wind flowing out of high-pressure systems and causes wind to
Back pressure device halts the sending of data packets until the buffers have been emptied and are once more capable of storing information. It also refers to an algorithm for routing data according to congestion gradients (see backpressure routing). Back pressure Back pressure (or backpressure) is a nonstandard term used to describe pressure opposed to the desired flow of fluid in a system. The term is misleading because pressure is a scalar quantity having a magnitude but with no direction associated with it. The obstructions or tight bends in a confined space such as an exhaust pipe oppose desired flow and reduce
