A set of tables and associated information for correcting reversing thermometers and computing dynamic height anomalies, compiled by E. C. Lafond (1951).
Industry:Weather
A south or southeast monsoon wind, favorable for the sailing of junks. The wind is known in Thailand, China, and Japan.
Industry:Weather
A simplified atmospheric chemical model, most commonly used for urban airshed models. In a lumped mechanism, organic compounds of similar chemical formula are grouped or “lumped” together and treated as a single representative species. For example, all aldehydes (acetaldehyde, propionaldehyde, etc. ) might be treated as a single molecule of formula RCHO, which undergoes chemical reactions representative of the aldehydes.
Industry:Weather
A series of U. S. Satellites designed for remote sensing and mapping of land areas. These satellites are launched into sun-synchronous orbits that return to image the same swath, two degrees wide, every 16 days. The primary imaging instrument on the first generation of Landsat satellites was a multispectral scanner, a four-channel radiometer with a ground resolution of 80 meters. Landsat-4 and -5 added a second imaging instrument, a thematic mapper, a seven- channel instrument with a ground resolution of 30 meters, used to study vegetation, geology, and other surface features. Landsat-1 (originally called ERTS) was launched in 1972, with Landsat-2 and -3 following in 1975 and 1978. Landsat-4 and -5 were launched in 1982 and 1984.
Industry:Weather
A section diagram plotted in the longitudinal dimension of a stream. It is usually used to plot energy grade lines.
Industry:Weather
A relatively low value of the zonal index that, in mid latitudes, indicates a relatively weak westerly component of wind flow (usually implying stronger north–south motion), and the characteristic weather attending such motion. A circulation pattern of this type is commonly called a low-index situation.
Industry:Weather
A relationship between the radius of a cloud droplet grown on a hygroscopic nucleus of a given dry mass, which decreases the vapor pressure with respect to a flat surface, and the radius of curvature of the drop, which increases the vapor pressure with respect to a flat surface and the equilibrium relative humidity.
Industry:Weather
A rating curve that has higher values of discharge for a certain stage when the river is rising than it does when the river is falling. Occasionally, the stage discharge curve describes a loop with each rise and fall of the river.
Industry:Weather
A radar echo from lightning. Lightning echoes are explained by the scattering of radar waves by the high concentration of free electrons created in the narrow channel of a lightning discharge. Because the electrons recombine quickly, lightning echoes have short durations, typically 1 s or less.
