What is "isotherms"

Usage examples of "isotherms".

In these the isotherms for every second degree are drawn in broken lines.

We see from the sections how nearly the isotherms and isohalins follow each other.

We see further in both sections, and especially in the southern one, that the isotherms and isohalins often have an undulating course, since the conditions at one station may be different from those at the neighbouring stations.

These undulating curves of the isotherms and isohalins are familiar to us in the Norwegian Sea, where they have been shown in most sections taken in recent years.

This state of things is clearly apparent in the sections, where the isotherms and isohalins run vertically for some way below the surface.
