buoyancy - 1. That property of an object that enables it to float on the surface of a liquid, or ascend through and remain freely suspended in a compressible fluid such as the atmosphere.
Buoyancy - the tendency of a body to float or to rise when submerged in a fluid; the power of a fluid to exert an upward force on a body placed in it ...
Buoyancy
In meteorology the upward force exerted upon a parcel of air by virtue of the density difference between itself and the surrounding air.

BUOYANCY - Lift produced when either an object displaces fluid (gas or liquid) or when a parcel is less dense than its surrounding environment. This rule is VERY important in developing convection.
where wB is the buoyancy velocity, Ssfc skin is the value of S at the solid surface of the earth, Smid-ML is the value of S near the middle of the convective mixed layer, and bS is an empirical parameter of order 10−3.
Lid(Also called cap.) A region of negative buoyancy below an existing level of free convection (LFC) where energy must be supplied to the parcel to maintain its ascent.
Severe supercell development is most likely in an environment possessing great buoyancy (CAPE) and large vertical wind shear. A Bulk Richardson Number of between 15 and 35 favor supercell development.
Severe multicell thunderstorms occur in environments possessing moderate vertical wind shear and moderate to large positive buoyancy (CAPE).
Bulk Richardson Number (BRN): It is the ratio of the buoyancy (CAPE) of a lifted parcel to the vertical wind shear of the environment in which the parcel is lifted.
Rossby waves are generated by atmospheric forcing from winds and buoyancy effects from solar heating and are the principal means by which localised climatic effects drive the global response of the ocean.
Convective clouds and heavy rains are fueled by increased buoyancy of the lower atmosphere resulting from heating by the warmer waters below.
Gravity wave (gravitational wave) A wave disturbance in which buoyancy (or reduced gravity) acts as restoring force on parcels displaced from hydrostatic equilibrium.
INSTABILITY (INSTBY)- Air that if lifted adequately will rise on its own due to positive buoyancy.
INTERPOLATION- Drawing an isopleth between known numerical values.
INVERSION (INV)- A temperature increase with height.
Convection Cell - Circulation that results from the uneven heating of a fluid; the warmer parts of the fluid expand and rise because of their buoyancy and the cooler parts sink.
They may slowly vary in size, since they are an area of negative buoyancy convection, and is associated with severe turbulence in the lower sections of the cloud. Related terms: mammatocumulus and Dave's Dictionary ...
Although they do not cause severe weather, they often accompany storms. They may slowly vary in size, since they are an area of negative buoyancy convection, and is associated with severe turbulence in the lower sections of the cloud.
There is also the gravitational force -ρg, but this is usually balanced by buoyancy; when it is not, it must also be included. If the path of the air is curved, it is also subject to the centrifugal force v2/r.
