puhangud

Puhangud is an Estonian term used to describe short, sudden releases or bursts of energy, gas, wind, or other material. As a plural noun, it is commonly applied in various scientific and descriptive contexts to refer to discrete instances of abrupt expulsion or rapid spikes in activity. The word is related to the root puh- associated with blowing or sudden release, and it often appears in technical glossaries and field notes.

In meteorology and climatology, puhangud may denote brief gusts of wind that occur over a narrow time window, often linked to convective activity, boundary interactions, or passing weather fronts. In geoscience disciplines such as volcanology or seismology, the term can describe explosive bursts of gas, ash, or energy that appear as rapid, transient events in observational data. In physics and engineering, puhangud can refer to transient spikes or pulses in signals, energy discharge, or mechanical systems.

The usage of puhangud is domain-specific, and its precise meaning depends on the context and accompanying qualifiers. There is no single universal definition; instead, the term functions as a descriptive label for high-intensity, short-duration events. In dictionaries and disclaimers, it is often presented as a general concept rather than a fixed technical term.
