That component of variability that is a function of the day of the year but is independent of the year.
Industry:Weather
In early ocean wave forecasting methods, the fraction by which the estimated energy of waves leaving the generation area is multiplied to obtain the forecast wave energy at a distant point, after reduction due to angular spreading.
Industry:Weather
An integral requirement for a system that is characterized by conservation of angular momentum. A description of the angular-momentum balance of a physical system includes 1) a description of the partition of absolute angular momentum within the system, and 2) a description of the mechanism by which absolute angular momentum is transferred from one portion of the system to another and also between the system and its surroundings. See also angular momentum, local angular momentum.
Industry:Weather
Correction to be made to an observed velocity when the direction of the current is not at right angles to the discharge section line.
Industry:Weather
In many meteorological contexts, the number of waves of a given wavelength required to encircle the earth at the latitude of the disturbance. If L is the wavelength, r the earth's radius, and φ the geographical latitude, the angular wavenumber k is given by k = 2πrcos φ/L.
Industry:Weather
The angular velocity of the earth (in the absolute coordinate system) is directed along the earth's axis toward the pole star and is equal in magnitude to 7. 2921 × 10−5 rad s−1.
Industry:Weather
The rate of rotation of a particle about the axis of rotation, with magnitude equal to the time rate of angular displacement of any point of the body. Angular velocity is a vector oriented in accordance with a right-hand rotation (i.e., when the fingers of the right hand are curved in the sense of rotation, the thumb points in the direction of the angular velocity vector).
Industry:Weather
Spreading of waves in space due to differences in direction of wave propagation.
