hamâmuni-ye âse-yi, âse-hamâmuni
Same as → axial symmetry.
Angular distance from the north point eastward to the intersection of the horizon with the vertical circle passing through the object. Azimuth is 0° for an object due north, 90° due east, 180° due south, and 270° due west. Altitude and azimuth constitute the the horizontal coordinate system.
From O.Fr. azimut, from Ar. as-sumut "the directions, ways," pl. of as-samt "the direction, way."
Sugân, from su "direction" + -gân direction suffix.
parhun-e sugân, dâyere-ye ~
Fr.: cercle d'azimut
Or, or pertaining to an → azimuth.
Fr.: angle azimutal
In → spherical coordinates, an angle measured from the x-axis in the xy-plane.
Azimuthal, adj. from azimuth; → angle.
azimuthal magnetic field
meydân-e meqnâtisi-ye sugâni
Fr.: champ magnétiquue azimutal
In the → solar dynamo model, a magnetic field that points from east to west or vice-versa.
Fr.: projection azimutale
A map projection on which the → azimuths of all points are shown correctly with respect to the center. A plane tangent to one of the Earth's poles is the basis for polar azimuthal projection.
azimuthal quantum number
adad-e kuântomi-ye sugâni
Fr.: nombre quantique azimutal
In quantum mechanics, a quantum number that distinguishes the different shapes of the orbitals.
Azimuthal, adj. from → azimuth; → quantum number.
