A region experiencing a fairly uniform climate according to specific criteria.
Industry:Weather
A received radar signal that has a polarization identical to that of the transmitted signal.
Industry:Weather
A region a few kilometers wide on either side of the shoreline where local thermal circulations such as the sea breeze and land breeze occur.
Industry:Weather
A reactive radical species with chemical formula ClO. Chlorine monoxide is an important inorganic chlorine compound in the stratosphere. This species is produced in the reaction of Cl atoms with ozone. Its conversion back to Cl without reforming O3 (e.g., via reaction with O atoms) results in chlorine-catalyzed ozone loss in the stratosphere.
Industry:Weather
A range of values of a variable; an interval used in dividing the scale of the variable for the purpose of tabulating the frequency distribution of a sample.
Industry:Weather
A radio direction finder for sferics using twin antennas and receivers applied to the CRT deflection circuits in such a way as to yield the source's direction.
Industry:Weather
A radiosonde with a carrier wave switched on and off in such a manner that the interval of time between the transmission of signals is a function of the magnitude of the meteorological elements being measured.
Industry:Weather
A radar optimized to detect clouds. This is usually a short wavelength radar often called millimeter radar, since its wavelength is usually near 8 mm (Ka band) or 3 mm (W band). Such shorter wavelengths give radars an advantage in cloud detection because of the radar scattering cross section for small particles varying as the inverse radar wavelength to the fourth power. Because attenuation caused by atmospheric liquid and from water vapor is serious at these short wavelengths, such radars are usually operated at ranges closer than about 20 km. They can be either of the scanning type or fixed in the vertical. Their good spatial resolution allows them to depict finescale cloud features and, when used in combination with other active (e.g., lidar) and passive (microwave and IR radiometers) sensors, can, under some conditions, be used to quantitatively map cloud ice and liquid water contents, particle sizes, and concentrations.
