An east wind on Lake Lugano (Italy and Switzerland), blowing from the Gulf of Porlezza.
Industry:Weather
An east wind that has crossed the Andes; the Andean foehn of the South American west coast. This term is sometimes used for a land breeze in areas where the Andes descend sharply into the Pacific Ocean. The corresponding sea breeze is the virazon. See fog wind.
Industry:Weather
An eastward flowing narrow current in the center of a subtropical gyre where the general water movement is weakly westward. The three subtropical countercurrents found in the North Pacific at 20°–26°N between Hawaii and Asia extend to depths of at least 800 m and have speeds of 0. 15 m s<sup>−1</sup>. Other subtropical countercurrents have been reported north of the Hawaiian Ridge and in the Coral Sea.
Industry:Weather
An emagram (temperature and logarithm of pressure as coordinates) with the isotherms rotated 45° clockwise to produce greater separation of isotherms and dry adiabats. See thermodynamic diagram.
Industry:Weather
An elongated area with relatively low pressure values when reduced to sea level.
Industry:Weather
An elevation band along mountain slopes where precipitation decreases with increasing elevation. In the lowest 1–2 km above the base of a mountain, precipitation typically increases with height until the zone of maximum precipitation is reached, above which precipitation decreases with height. This zone of decrease is the precipitation inversion.
Industry:Weather
An electronic instrument used for the production of electromagnetic or acoustic signals with certain desired characteristics. It is useful in testing and calibration.
Industry:Weather
An electronic device for the measurement of the average received power from a target illuminated by a pulsed transmission.
Industry:Weather
An electromagnetic transient launched by a lightning discharge of large amplitude within the earth–ionosphere cavity. Originally named by Toshio Ogawa (1967), the “Q” connotes “quiet” and characterizes a transient in which the fundamental 8-Hz mode of the Schumann resonances is the dominant contributor. In general, a mix of Schumann modes makes up a Q burst.
Industry:Weather
An efficient computational algorithm for digital radar data processing that provides estimates of the mean Doppler velocity and the Doppler spread. Based on the properties of the autocorrelation function of the radar signal in successive pulses, this procedure is usually much faster than the fast Fourier transform algorithm, but it does not yield the complete Doppler spectrum.
