air parcel
noun
(physics,
meteorology)
An
imaginary
body
of
air
to
which
may
be
assigned
any
or
all
of
the
basic
dynamic
and
thermodynamic
properties
of
atmospheric
air.
A
parcel
is
large
enough
to
contain
a
very
great
number
of
molecules,
but
small
enough
so
that
the
properties
assigned
to
it
are
approximately
uniform
within
it
and
so
that
its
motions
with
respect
to
the
surrounding
atmosphere
do
not
induce
marked
compensatory
movements.
It
cannot
be
given
precise
numerical
definition,
but
a
cubic
foot
of
air
might
fit
well
into
most
contexts
where
air
parcels
are
discussed,
particularly
those
related
to
static
stability.

(physics, meteorology) An imaginary body of air to which may be assigned any or all of the basic dynamic and thermodynamic properties of atmospheric air. A parcel is large enough to contain a very great number of molecules, but small enough so that the properties assigned to it are approximately uniform within it and so that its motions with respect to the surrounding atmosphere do not induce marked compensatory movements. It cannot be given precise numerical definition, but a cubic foot of air might fit well into most contexts where air parcels are discussed, particularly those related to static stability.
