This type of motion causes a smoke plume from a continuous point source to meander ....

OBS

... accidental situation. ... The mode of release depends on the chemical and how it is stored and on the nature of the rupture... on the containing vessel. ... A gas leak from a tank would act as a "point" source of vapour emissions, whereas as a liquid leak spreading on a land or water surface and evaporating would act as an "area" source. Both of these types of sources would be of a "semi-continuous" nature, whereas a catastrophic failure ... would result in an "instantaneous" cloud (or "puff") source. ... [in] the latter case, ... a large amount of material is released in a short time.
