Science / Chemistry / Isobar: 1. A contour line that corresponds to values measured at identical pressures. For example, curves on a plot of gas volumes measured at different temperatures in an open container are isobars. 2. Nuclides that have the same isotopic mass but different atomic number.


Technology / Home Audio / Isobarik: Sometimes spelled Isobaric, this is an enclosure design in which two or more Drivers are coupled together by a sealed air mass to operate as a single driver. With proper sealing and design, very impre MORE


Science / Chemistry / Isobaric: Having constant pressure. MORE

Gradient Wind

Science / Weather / Gradient Wind: A steady horizontal air motion along curved parallel isobars or contours in an unchanging pressure or contour field, assuming there is no friction and no divergence or convergence. MORE

Closed Low

Science / Weather / Closed Low: A region of low pressure distinguished by a center of counterclockwise circulation (in the Northern Hemisphere), and is surrounded by one or more isobars or height contours. Closed lows aloft (i.e., a MORE

Friction Layer

Science / Weather / Friction Layer: The thin layer of atmosphere adjacent to the earth's surface. Surface friction is effective in slowing down wind up to approximately 1,500 to 3,000 feet above the ground. Above this level, air tends t MORE

Tropical Depression

Science / Weather / Tropical Depression: A tropical cyclone in which the maximum sustained surface winds are 38 miles per hour (33 knots) or less. Characteristically having one or more closed isobars, it may form slowly from a tropical distu MORE
