In the high-pressure cell, a heated sample (5) is exposed to a reactant gas stream (3) through a proximate nozzle (4). Products and reactants are probed by a capillary (1) for quantitative gas analysis. The distance of the capillary to the sample surface, as well as the nozzle-sample distance, can be varied by individual manipulators (2) and (6Web

High-pressure cells are another type of pressure pattern observed on analyzed weather maps. A high-pressure area is surrounded on all sides by lower pressure. We call it a High for short. It may also be referred to as an anticyclone because the windflaw around a High is anticyclone (clockwise in the Northern …

During the summer the subtropical high pressure cell over the eastern Pacific has migrated to its northern most limit and expanded in size. The subsiding air of the subtropical high is compressed as it descends through the atmosphere, creating a warm layer of air aloft. In addition, adiabatic heating lowers the relative humidity, preventing the ...Web
