Pertaining to a body moving in a fluid, especially air. Sometimes the term aerodynamic is applied to a dynamically stable body (e.g., aircraft or automobile) with a low drag coefficient.

As originally formulated, a statement of the conservation of energy (per unit mass) for an inviscid fluid in steady motion.
The specific energy is composed of the kinetic energy (1/2)''v''<sup>2</sup>, where ''v'' is the speed of the fluid; the potential energy ''gz'', where ''g'' is the acceleration of gravity and ''z'' the height above an arbitrary reference level; and the work done by the pressure forces ∫ α''dp'', where ''p'' is the pressure, α the specific volume, and the integration is always with respect to values of ''p'' and α on the same parcel. Thus, the relationship

The derivative of the Coriolis parameter with respect to latitude.
The beta-plane approximation, useful for the study of equatorial and midlatitude flow, assumes that the Coriolis parameter varies linearly with latitude. Explicitly, the Coriolis parameter is given approximately by

The model, introduced by C. G. Rossby, of the spherical earth as a plane with a rate of rotation ''f'' (corresponding to the Coriolis parameter) that varies linearly with the north–south direction ''y'':

One of the three commonly detectable points of zero polarization of skylight, neutral points, lying along the vertical circle through the sun; the other two are the Arago point and Brewster point. <br>The Babinet point typically lies only 15° to 20° above the sun, and hence is difficult to observe because of solar glare. The existence of this neutral point was discovered by Babinet in 1840.
