Industry:Weather
A line of equal or constant temperature. A distinction is made, infrequently, between a line representing equal temperature in space, choroisotherm, and one representing constant temperature in time, chronoisotherm. See thermoisopleth.
Industry:Weather
A line or surface showing the depths in oceans or lakes at which points have the same temperature. Isobathytherms are usually drawn to show cross sections of the water mass.

A line on a map along which an equal percentage of the total annual precipitation falls in a given season or month; literally means “equal parts. ”
Industry:Weather
A line of equal or constant pressure; an isopleth of pressure. In meteorology, it most often refers to a line drawn through all points of equal atmospheric pressure along a given reference surface, such as a constant-height surface (notably mean sea level on surface charts), an isentropic surface, the vertical plane of a synoptic cross section, etc. The pattern of isobars has always been a main feature of surface-chart analysis. Isobars are usually drawn at intervals of one millibar or more, depending on the scale needed to identify or illustrate a specific meteorological pattern.
