What is a plume in environmental science?

A plume is a column/space in air, water, or soil of one fluid moving through another that contains pollutants release from a source. A plume usually moves away from its source and widens. A plume’s shape is like that of a long feather.

What is plume in atmosphere?

A plume is a column of liquid, gas, or dust, moving through another. In general we use the term plume to describe things like smoke coming out of a chimney or steam from a smokestack at a power plant. A plume could also be rain cloud, a snow cloud, and even your breath!

What is pollution plume?

Air pollution emission plume – flow of pollutant in the form of vapor or smoke released into the air. Plumes are of considerable importance in the atmospheric dispersion modelling of air pollution.

What is plume study?

It is important to understand the effect and of chemical vapours being emitted from laboratory fume cupboard stacks. Laboratory emissions can end up in air-conditioning air intakes, neighbouring buildings and expose workers on the roof.

What is a plume in an aquifer?

Groundwater plume means groundwater that has been polluted by a release and in which one or more substances from such release is present at a concentration above the laboratory reporting limit.

What is a plume and types?

(1) Looping Plume: Plume is formed when the environmental lapse rate becomes more than the Dry Adiabatic Lapse Rate i.e. occurs in a super adiabatic environment. In an unstable Atmosphere, rapid air moments take place vertically both upward and downward And the plume becomes Looping Plume.

What are plumes What are the types of the plumes?

Types of Plume

  • Coning Plume. Formed when horizontal wind velocity exceeds 32 km/h and cloud blocks solar radiation during the day and terrestrial radiation during the night.
  • Fanning Plume.
  • Looping Plume.
  • Neutral Plume.
  • Lofting Plume.
  • Fumigating Plume.
  • Trapping Plume.

What is plume groundwater?

What is a plume in engineering?

A thermal plume is one which is generated by gas rising above heat source. The gas rises because thermal expansion makes warm gas less dense than the surrounding cooler gas.

Which type of plume occur during winter night?

This is known as a lofting plume.
