The study of snow and ice on the earth's surface. It includes the study of glaciers, snow, and sea ice.
Industry:Weather
The structure and combination of processes set up by the conductive earth, the conductive ionosphere, and all agents of electrification within the resistive troposphere. The so-called dc global circuit is characterized by the ionosphere potential and the ac global circuit refers to the Schumann resonances within the earth–ionosphere waveguide.
Industry:Weather
The spots of light reflected from a point source by the surface of the sea.
Industry:Weather
The sharp increase in wind speed often associated with the early mature stage of a thunderstorm cell. It occurs with the passage of the discontinuity zone that is the boundary of the cold-air downdraft. The first gust can reach destructive speeds.
Industry:Weather
The speed of an airborne object relative to the earth's surface. It is the magnitude of the vector sum of the object's velocity with respect to the air and the wind velocity, or, expressed in a different manner, the algebraic sum of the aircraft's airspeed and the wind factor.
Industry:Weather
The secondary division of geologic time, delimited by moderate but usually global crustal events, changes in sea level and/or climate, or biotic changes, sometimes in a relatively localized area. Two or more periods are required to make up a geologic era, and each period comprises two or more geologic epochs.
Industry:Weather
The science of the development and care of forests; the management of growing timber. Climatology plays an important part, including the study of the general livability of a forest to unfavorable weather conditions such as heavy snow, frost, glaze, strong winds, and drought (fire weather), and also the analysis of the microclimate of the forest itself and the effect of this on the reproduction, spread, and control of pests.
