ISOTHERAL
I*soth"er*al, a.
Defn: Having the nature of an isothere; indicating the distribution of temperature by means of an isothere; as, an isotheral chart or line.
ISOTHERE
I"so*there, n. Etym: [Iso- + Gr. (Phys. Geog.)
Defn: A line connecting points on the earth's surface having the same mean summer temperature.
ISOTHERM
I"so*therm, n. Etym: [Iso- + Gr. (Phys. Geog.)
Defn: A line connecting or marking points on the earth's surface having the same temperature. This may be the temperature for a given time of observation, or the mean temperature for a year or other period. Also, a similar line based on the distribution of temperature in the ocean.
ISOTHERMAL I`so*ther"mal, a. Etym: [Cf. F. isotherme.] (a) Relating to equality of temperature. (b) (Phys. Geog.) Having reference to the geographical distribution of temperature, as exhibited by means of isotherms; as, an isothermal line; an isothermal chart. Isothermal line. (a) An isotherm. (b) A line drawn on a diagram of energy such that its ordinates represent the pressures of a substance corresponding to various volumes, while the absolute temperature is maintained at a constant value. — Isothermal zones, spaces on opposite sides of the equator having the same mean temperature, and bounded by corresponding isothermal lines.
ISOTHERMOBATH
I`so*ther"mo*bath, n. Etym: [Iso- + Gr. (Phys. Geog)
Defn: A line drawn through points of equal temperature in a vertical section of the ocean.
