ISENTROPIC LIFT Lifting of air that is traveling along an upward-sloping isentropic surface. Isentropic lift often is referred to erroneously as overrunning, but more accurately describes the physical process by which the lifting occurs.
ISENTROPIC LIFT / DESCENT- Lifting or sinking of air along constant potential temperature (theta) surfaces. WAA (especially over shallow frontal boundaries) leads to lift while CAA leads to descent. ISOBAR- A line of constant surface pressure.
Isentropic lift often is referred to erroneously as overrunning, but more accurately describes the physical process by which the lifting occurs.
ISENTROPIC LIFT - Lifting of unsaturated air as it moves over a boundary such as a front or dryline or even an upslope such as high terrain.
during periods of isentropic lift, when an unstable layer of air is present aloft.
Identify thermal advection patterns, vertical wind shear, depths of frontal surfaces, and the development of isentropic lift situations. The usefulness of this radar product is sometimes limited by lack of scatters at times.
a layer in which the lowest portion is based above the earth's surface. Elevated convection often occurs when air near the ground is relatively cool and stable, e.g., during periods of isentropic lift, when an unstable layer of air is present aloft.
10 minute intervals depending on the Volume Coverage Pattern). It is used to: 1) Identify jets (low/mid/high level); and 2) Identify thermal advection patterns, vertical wind shear, depths of frontal surfaces, and the development of isentropic lift ...
