1000 - 500 mb thickness
Lifting Index United States.
THICKNESS The thickness of a layer in the atmosphere is proportional to the mean temperature of that whole layer. The layer most often used in meteorology is between 1000 and 500 millibars.
Thickness
Thickness usually refers to the depth of the 1000-500 hPa layer in the atmosphere. However charts are also produced for thicknesses of other layers in the atmosphere as well.
Thickness
The vertical distance between two levels of constant atmospheric pressure, usually between 1000 hPa and 500 hPa.
thickness - In synoptic meteorology, the vertical depth, measured in geometric or geopotential units, of a layer in the atmosphere bounded by surfaces of two different values of the same physical quantity, usually constant-pressure surfaces.
THICKNESS: The difference in height between two atmospheric pressure levels.
THICKNESS: The height difference between two atmospheric pressure levels and is related to the average temperature in the column.
THUNDER: The sound caused by a lightning stroke as it heats the air and causes it to rapidly expand.
THICKNESS LINE- A line of constant geopotential thickness. Thickness increases by either increasing the temperature or increasing water vapor content of the air.
Thickness: what is it?
A. 'Thickness' is a measure of how warm or cold a layer of the atmosphere is, usually a layer in the lowest 5 km of the troposphere; high values mean warm air, and low values mean cold air.
THICKNESS - The difference, usually in meters, between two pressure intervals. For example, if the 850 MB is 1500 M above the ground and the 700 MB is 3000 M, the 850-700 thickness will be 1500 M.
The thickness or opaqueness of water caused by the suspension of matter. The turbidity of rivers and lakes increases after a rainfall.
Turbulence
Irregular motion of the atmosphere, as indicated by gusts and lulls in the wind.
Ozone Column Thickness or Total Column Ozone: The total amount of ozone present in a column of the Earth's atmosphere from the surface to the top of the atmosphere. It includes both surface level ozone and ozone found in the ozone layer.

optical thickness (optical depth) In calculating the transfer of radiant energy, the mass of an absorbing or emitting material lying in a vertical column of unit cross-sectional area and extending between two specified levels.
Crest Width (Top thickness): The thickness or width of a dam at the level of the crest (top) of the dam. The term "thickness" is used for gravity and arch dams and "width" for other types of dams.
Thermal WindIt is a theoretical wind that blows parallel to the thickness lines, for the layer considered, analogous to how the geostrophic wind blows parallel to the height contours.
The great density and thickness (usually many thousands of feet) of this cloud prevent observation of the sun; this, plus the absence of small droplets in its lower portion, gives nimbostratus the appearance of dim and uniform lighting from within.
X-rays penetrate various thicknesses of all solids, and they act on photographic plates in the same manner as light. Secondary x-rays are produced whenever x-rays are absorbed by a substance.
A glacier of considerable thickness and more than 50,000 sq km in area. It forms a continuous cover of ice and snow over a land surface. An ice sheet is not confined by the underlying topography but spreads outward in all directions.
The "omega equation" used in numerical weather models is composed of two terms, the "differential vorticity advection" term and the "thickness advection" term.
Spaceborne radars are used for Earth observations, bouncing radar waves off land and ocean surfaces to study sea-surface conditions, ice thickness, and land surface features.
This contraction leads to a decrease in the distance, or "thickness", between constant pressure surfaces within the cooled air.
The portion of the electromagnetic spectrum that has a very short wave length. It has a wavelength longer than gamma rays, yet shorter than visible light. X-rays can penetrate various thicknesses of all solids, and when absorbed by a gas, ...
Cloud Height- the altitude of the cloud base above the local terrain or the difference in height between the cloud top and the cloud base; (sometimes called "thickness" or "depth" of the cloud) ...
Globule or piece of ice, with a diameter varying between 5 and 50 mm or even more, the fall of which constitutes hail. Hailstones consist almost entirely of transparent ice, or of a series of layers of transparent ice with a thickness of at least 1 ...

Talik or tabetisol layers may vary from a few inches to several feet in thickness and support a number of micro- organisms which are tolerant to cold temperatures. These soils are usually found at fairly high latitudes.
If these bodies dominate, then a turbulent boundary layer is formed, of a thickness we shall denote by ε, and the surface is classed as aerodynamically rough.
ozoneOzone measurements are given in Dobson units and are integers with 3 significant figures. A Dobson Unit represents the physical thickness of the ozone layer if it were brought to the earth's surface.
