Meteorology
orbit number
Weather; Meteorology
A particular circular path beginning at the satellite's ascending node. The orbit number from launch to the first ascending node is designated as zero.
orbital elements
Weather; Meteorology
A collection of quantities that, together, describe the size, shape, and orientation of an orbit. The classical orbital elements include the semimajor axis, eccentricity, inclination, argument of ...
orbital motion
Weather; Meteorology
In hydrodynamics, the motion of a fluid particle induced by the passage of a progressive gravity wave. When the wave height is small and the fluid depth is great, the orbit is a circle the radius of ...
orbital velocity
Weather; Meteorology
As an ocean wave propagates, the water itself moves in an approximately circular motion (in deep water), with the amplitude of the motion decaying with depth below the sea surface. The velocity ...
ordinary cell
Weather; Meteorology
The most basic component of a convective storm, consisting of a single main updraft that is usually quickly replaced by a downdraft once precipitation begins. Ordinary cells are especially observed ...
ordinary ray
Weather; Meteorology
When a plane wave is incident on a uniaxial medium (an anisotropic medium with two equivalent orthogonal directions), two transmitted waves result: the ordinary ray (or wave), the phase velocity of ...
ordinate
Weather; Meteorology
The vertical coordinate in a two-dimensional system of rectangular Cartesian coordinates; usually denoted by ''y''. Also, the vertical axis of any graph. See abscissa.
