A second gust of wind or air that follows an initial blow, or a secondary effect that comes after an initial impact or event.
Compound of 'after' and 'blow' (Old English blawan, 'to blow or breathe'). The term appears in nautical and meteorological contexts, describing the phenomenon of wind patterns that follow a primary wind event.
Afterblows are why storms are sometimes more dangerous in their wake than at their peak—a final gust after the initial blow catches people unprepared and can cause additional damage or capsizing. Weather forecasters have learned to warn about these secondary gusts.
