The study of the physical state of the atmosphere derived from vertical sounding data plotted on thermodynamic diagrams.
Industry:Weather
The study of the forces exerted on and the flow around bodies, especially aircraft, moving relative to a gas, especially the atmosphere. Aerodynamics is sometimes used as a synonym for the science of flight.
Industry:Weather
The component of force exerted by the air on a liquid or solid object (such as a raindrop or airplane) that is parallel and opposite to the direction of flow relative to the object.

Industry:Weather
A method utilizing grid navigation to simplify flight problems attendant to pressure-pattern flight. A map projection is used in which the great circle course approximates a straight line, and a rectangular grid overlay is superimposed on the map projection and oriented along the central meridian of the projection. Then the great circle course makes equal angles with all north–south lines on the grid. When the net drift-correction angle is applied to correct for wind effect, the entire course may be flown on a single heading with respect to the rectangular grid overlay.

1. Same as descriptive meteorology. 2. (Rare. ) The so-called nonprofessional work of meteorology: observing, map plotting, maintaining records, etc.
Industry:Weather
In general, any self-recording instrument carried aloft by any means to obtain meteorological data.
Industry:Weather
A surface with irregularities sufficiently large that the turbulent boundary layer reaches right down to the surface. Individual roughness elements are higher than the laminar (viscous) sublayer. Virtually all surfaces on the earth, except glassy-smooth water surfaces, are aerodynamically rough. Compare aerodynamically smooth surface.
Industry:Weather
The force exerted by a moving fluid (especially air) on a body immersed in it. The component of the aerodynamic force parallel to the direction of flow is called the drag.
Industry:Weather
An instrument used for the measurement of the forces exerted on the surfaces of instruments exposed to flowing air. It is frequently used in tests made on models in wind tunnels. Compare aerostatic balance.
