isobar (ī`səbär') or isobaric line (ī'səbăr`ĭk), line drawn on a weather map through points of equal atmospheric pressure. Isobars are used to define cyclones (low-pressure regions) and anticyclones (high-pressure regions). Weather maps are designed to depict the horizontal pressure distribution across an area of land, but atmospheric pressure also varies vertically, i.e., with altitude. To eliminate any consideration of the vertical variations of pressure, the barometer readings at all stations are reduced to their corresponding sea-level pressures before the isobars are drawn. |

Their straightforward design, a bi-level matrix of Isobar superthermal conductors, redistributes the energy generated by standard cartridge heaters with unparalleled evenness, according to the literature. The geostrophic wind blows parallel to isobars or height contours, with lower pressure/heights to the left (right) of the flow in the northern (southern) hemisphere, via the Buys-Ballot law. Isobar heat pipes and isoplatens for optimizing thermoset and rubber molding. |
