The current determined by dividing the displacement of a fluid particle by the time traveled.
Industry:Weather
The correlation between the properties of a flow following a single parcel of fluid through its space and time variations. Compare Eulerian correlation; see correlation coefficient.
Industry:Weather
The branch of dynamics that describes the properties of pure motion without regard to force, momentum, or energy. Translation, advection, vorticity, and deformation are examples of kinematic variables.
Industry:Weather
The branch of hydrology devoted to the study of the movement and occurrence of water in karst.
Industry:Weather
The component, perpendicular to the relative wind and in the plane of symmetry, of the total force of air on an aircraft or airfoil. It must be specified whether this applies to a complete aircraft or the parts thereof. In the case of a lighter-than-air craft, this is often called dynamic lift.
Industry:Weather
The change in a variable during a specified interval of time at a fixed point in the coordinate system in use. See local derivative.
Industry:Weather
The behavior of a fluid with a Reynolds number typically greater than 104 to 106, which usually occurs within the atmosphere. The main property of such flows is a constant friction stress within the surface layer that depends only on relative roughness but not on the Reynolds number itself. Thus, molecular viscosity and qualities occurring in flow descriptions that are dependent on the Reynolds number may be totally ignored.
Industry:Weather
The ancient Greek name for the southwest wind, which is the sea breeze in Athens. On the Tower of the Winds it is represented by a bare-legged young man carrying a piece of a trireme. This may indicate either that the wind favored home-coming ships or that, when stormy, it caused wrecks. Today the name is applied to any hot wind, usually the sirocco.
Industry:Weather
The angular distance along the meridian from the point in question to the equator. Latitude is normally described as so many degrees north or south of the equator. Compare longitude.
