1. A violent disturbance of the atmosphere, attended by wind, rain, snow, hail, or thunder and lightning; hence, often, a heavy fall of rain, snow, or hail, whether accompanied with wind or not. We hear this fearful tempest sing, yet seek no shelter to avoid the storm. (Shak)
2. A violent agitation of human society; a civil, political, or domestic commotion; sedition, insurrection, or war; violent outbreak; clamor; tumult. I will stir up in England some black storm. (Shak) Her sister Began to scold and raise up such a storm. (Shak)
Storm is often used in the formation of self-explained compounds; as, storm-presaging, stormproof, storm-tossed, and the like. Magnetic storm. See Magnetic. Storm-and-stress period [a translation of G. Sturm und drang periode], a designation given to the literary agitation and revolutionary development in Germany under the lead of Goethe and schiller in the latter part of the 18th century.
Storm, Tempest. Storm is violent agitation, a commotion of the elements by wind, etc, but not necessarily implying the fall of anything from the clouds. Hence, to call a mere fall or rain without wind a storm is a departure from the true sense of the word. A tempest is a sudden and violent storm, such as those common on the coast of Italy, where the term originated, and is usually attended by a heavy rain, with lightning and thunder. Storms beat, and rolls the main; O! beat those storms, and roll the seas, in vain. (pope) What at first was called a gust, the same Hath now a storm's, anon a tempest's name. (Donne)
Origin: AS. Storm; akin to D. Storm, G. Sturm, Icel. Stormr; and perhaps to Gr. Assault, onset, Skr. S to flow, to hasten, or perhaps to L. Sternere to strew, prostrate (cf. Stratum). 166.
