A diagram in which one coordinate is time and the other is distance (usually height, in which case it is a vertical time section). Compare cross section, profile, time–height section.
Industry:Weather
The condition in which the thermal environment of a homeothermic animal is such that its heat production (metabolism) is not increased either by cold stress or heat stress. The temperature range in which this minimum occurs is called the zone of thermal neutrality. For humans, this zone is 29°–31°C (84°–88°F).

Industry:Weather
The quantity of heat required to complete some stage, or the whole, of a plant's growth. It was first investigated by Réaumur about 1735, using the sum of the mean daily temperatures. It may also be measured by the sum of air temperatures above some standard such as 42°F (see degree-day). In modern agricultural climatology this concept has been largely abandoned in favor of complex influence factors such as evapotranspiration. It has also been established that soil temperatures at or somewhat below 10 cm are more important for plant growth than air temperature.
Industry:Weather
An iceberg that has broken off from an ice shelf. Newly formed tabular icebergs have nearly vertical sides and flat tops. In the Antarctic, they may be tens of kilometers wide, up to 160 km (100 miles) long, and as much as 300 m (1000 ft) thick, with about 30 m (100 ft) exposed above the sea surface. In the Arctic, large icebergs of this type are called ice islands, but they are considerably smaller than the largest of the antarctic variety.
Industry:Weather
A Russian term applied to permanently unfrozen ground in regions of permafrost. This usually applies to a layer that lies above the permafrost but below the active layer, that is, when the permafrost table is deeper than the depth reached by winter freezing from the surface. Talik is also found within and beneath permafrost; when it occurs beneath the permafrost it is equivalent to subgelisol.
Industry:Weather
A type of electrical thermometer consisting of two thermocouples that are series connected with a potentiometer and a constant-temperature bath. One couple, called the reference junction, is placed in a constant-temperature bath, while the other is used as the measuring junction. The measuring junction can be made physically very small in order to have practically a negligible thermal time constant. See bottle thermometer.
