Low-pressure area mesocyclones, but more often develop from environments of high instability and low vertical wind shear. In deserts, lack of ground and plant moisture that would normally provide evaporative cooling can lead to intense, rapid solar heating of the lower layers of air. The hot air is less dense than surrounding cooler air. This, combined with the rising of the hot air, results in a low-pressure area called a thermal low. Monsoon circulations are caused by thermal lows which form over large areas of land and their strength is driven by how land heats more quickly than the surrounding nearby ocean.
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
