High-pressure area are alternatively referred to as anticyclones. On English-language weather maps, high-pressure centers are identified by the letter H in English, within the isobar with the highest pressure value. On constant pressure upper level charts, it is located within the highest height line contour. Highs are frequently associated with light winds at the surface and subsidence through the lower portion of the troposphere. In general, subsidence will dry out an air mass by adiabatic, or compressional, heating. Thus, high pressure typically brings clear skies. During the day, since no clouds are present to reflect sunlight, there is more incoming shortwave solar
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
