In the United States, a strong downslope wind on the eastern (Nevada) side of the Sierra Nevada in northern California. This term has been applied to two different types of wind: 1) a foehn or chinook wind during the cold season; and 2) an afternoon wind down the east-facing canyons and valleys during the warm season. The latter may result from afternoon convective mixing or may be related to California sea-breeze effects. See mountain–valley wind systems.
Industry:Weather
In the interpretation of the records of sunshine, the difference between the time of sunrise and the time at which a record of sunshine first began to be made by the sunshine recorder; and conversely at sunset. This correction is added only when the horizon is clear during the period.
Industry:Weather
In the Northern Hemisphere, a wind that rotates in a clockwise direction with increasing height; the opposite of backing wind.

In synoptic meteorology, the vertical depth, measured in geometric or geopotential units, of a layer in the atmosphere bounded by surfaces of two different values of the same physical quantity, usually constant-pressure surfaces. See thickness chart.
Industry:Weather
In synoptic meteorology, the inclination to the vertical of a significant feature of the circulation (or pressure) pattern or of the field of temperature or moisture. For example, troughs in the westerlies usually display a westward tilt with altitude in the lower and middle troposphere.

In simple terms, the vertical distance between a wave crest and the preceding or following wave trough. However, in a random sea, a variety of interpretations are possible. A commonly used definition is the so-called zero-upcrossing wave height, which is the range of elevations (difference between highest crest and lowest trough) between two successive upcrossings of the mean water level. See wave frequency, wave length, wave period.
