gondola

’gonds-la n. a boat-like car of a dirigible balloon. gore go:z ”. one of the many triangular or lune-shaped pieces of silk or other material which together form the envelop of the gasbag of a balloon. go amer ‘go so-moi 7”. a wébzlike or gauzy fabric or stzuc- ‘ture: as, the *ge amer wings of an insect. go amer-like ‘gosomozjaik adj. like ge amer; webzlike, gauzy: as, *ge amerzlike constzuction. gourd-whistle ‘go:zd,wisot n. a light wind-blown whistle made of tubes fastend to a gourd body or wind-chest, attacht by the Chinese to the tails of flying pigeons. governing-plane ‘gavoznin,preen n. one of the aeroplanes forming part of a dirigible balloon or airshtp and used to govern or control the direction or equilibrium of the craft. gradient ‘gee-di-ont ». a series or system of steps, grades, or degrees; specifically, the rate at which a variable quantity changes; rate of variation; rate of change. adiabatic gradient, the vertical gradient of the temperature of any portion of the atmosfere under adiabatre conditions; the rate of change in the temperature of the air (with change of altitude) caused by change of velume and concomitant transformation of internal energy of the air concernd, but net the result of any transference of heat to or from the surrounding air; the rate at which the temperature of the atmosfere varies (as mesured at different heights above the earth) when the variation of its temperature is due solely to expansion or compre ion of the air resultrng from a decrease or an increase in the external airzpre ure and the accompanying absorption or evolution of mternal heat. barometric gradient, the gradient of barometric pre ure with distance; the rate of change of atmosferzce pre ure along the surface of the earth, usually mesured (en the wetherzmap) along a line perpendicular to the isobars at any point. critical barometric gradient, the barometgre gradient which would be maintaind under stedy wind-conditions; the rate at which atmosferzc pre ure along the surface of the earth would vary under the influence of a stedy wind or stedy system of winds. cyclonal gradient, the barometric gradient directed toward the center of a cyclone; the rate at which the atmosferzc pre ure along the earth’s surface would vary if mesured (on the wether-map) along a line extending from any given point toward the cental point of mrmzmum pre ure in a rotary system of winds. electric gradient, the gradient of the electric potential of the atmosfere; the vertical or the herirzental rate of change in the potential function of the electricity in the air.
