Low-pressure area most active tropical cyclone basin on Earth. Wind is initially accelerated from areas of high pressure to areas of low pressure. This is due to density (or temperature and moisture) differences between two air masses. Since stronger high-pressure systems contain cooler or drier air, the air mass is denser and flows towards areas that are warm or moist, which are in the vicinity of low-pressure areas in advance 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. Thus, stronger areas of low pressure are
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
