The eastward current that forms the northern part of the North Pacific subtropical gyre. It originates from the Kuroshio Extension east of the Emperor Seamounts (170°W) and maintains the Arctic Polar Front with the Aleutian or Pacific Subarctic Current, with which it experiences much mixing as it proceeds eastward. A broad band of flow some 2000 km wide, it feeds its water into the California Current on approaching the North American coast.

The relatively weak general area of high pressure that, as shown on mean charts of sea level pressure, covers most of North America during winter. This pressure system is not nearly as well-defined as the analogous Siberian high.

A northerly foehn wind blowing down the Italian side of the Alps. The northern slopes are normally cooler than the southern slopes, and the dynamic warming is often insufficient to overcome the difference of temperature. Hence a warm dry northerly wind of foehnlike character occurs less frequently than the south foehn.

1. The winter north wind in Spain. 2. A strong cold northeasterly wind in Mexico and on the shores of the Gulf of Mexico. It results from an outbreak of cold air from the north; actually, the Mexican extension of a norther. See chocolatero. 3. A norther in Central America. See papagayo.

A seawater preparation, the chlorinity of which lies between 19. 30 and 19. 50 grams per kilogram (or per mille) and has been determined to within ±0. 001 per mille. Normal water is used as a convenient comparison standard for chlorinity measurements of seawater samples by titration. It is prepared by the Hydrographical Laboratories, Copenhagen, Denmark.

The components of the stress tensor that are normal to the faces of the fluid element.

A solution of the tangent linear model of a set of differential equations. Usually a wave type structure is assumed of the form ''e<sup>ik(x − t)</sup>'' and solutions with imaginary ''k'' are considered.
