Pressure system low pressure, while As depict anticyclonic flow or likely positions of high-pressure areas. An area of confluent streamlines shows the location of shearlines within the tropics and subtropics. Pressure system A low-pressure area, or "low", is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis. Within the field of atmospheric dynamics, areas of wind divergence aloft occur in two areas: Diverging winds aloft ahead of these troughs
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
