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
Low pressure molding Millions of circuit boards are successfully over-molded without causing any harm in the process. A low injection pressure does not stress a fragile solder joint. Low Pressure Molding process was initially invented in Europe in the 1970s by adhesives companies like Henkel AG & Co. KGaA in Germany and Bostik in France to seal connectors and create strain reliefs for wires. The first commercial use of the Low Pressure Molding process was in the automotive industry. The driving force was to replace toxic and cumbersome potting processes, faster cycle times, lighter parts and environmentally safe components and for some applications
