Any graphical means of displaying the distribution of meteorological data over a given (usually extensive) area of the earth's surface.
Industry:Weather
Any current driven directly by the wind stress or indirectly by the pressure gradients set up by the divergence or curl of the wind stress. See Also surface current.
Industry:Weather
Annual tabulations of daily predictions of the times and heights of high water and low water at various places. Such tables are constructed from astronomical data and from the results of harmonic analyses of previous observations at the desired point. They are compiled and issued by national hydrographic authorities, for example, the U. S. Coast and Geodetic Survey. The heights in tide tables are usually measured from chart datum rather than mean sea level.
Industry:Weather
Any cloud composed entirely of liquid water drops; to be distinguished from an ice- crystal cloud and from a mixed cloud. Above the 0°C level some clouds may be entirely liquid within the limitations of measurement (1 crystal per 10 liters) even at low temperatures (−30°C as some lenticular clouds); on the other hand, some clouds not far below 0°C may contain considerably higher ice concentrations.
Industry:Weather
An optical instrument, similar to a surveyors's transit telescope, used to visually track a radiosonde balloon and determine its azimuth and elevation angles while in flight.

An octagonal marble building in Athens erected not later than 35 BC and still standing. The sides face the points of the Athenian compass and carry a frieze of male personifications of the winds from those directions: Boreas (N), Kaikias (NE), Apheliotes (E), Euros (SE), Notos (S), Lips (SW), Zephyros (W), and Skiron (NW). These figures are reproduced on the tower of the Radcliffe Observatory, Oxford, United Kingdom, and in the Library of the Blue Hill Observatory near Boston, Massachusetts. The Tower was not a meteorological observatory, though it originally carried a wind vane on the roof, but was built to measure time, the walls bearing sundials, with a water clock inside for use during cloudy weather.
