Scale height - Wikipedia
In atmospheric, earth, and planetary sciences, a scale height, usually denoted by the capital letter H, is a distance (vertical or radial) over which a physical quantity decreases by a factor of e (the base of natural logarithms, approximately 2.718).
atmosphere of a planet is by its 'scale height'. This quantity represents the vertical distance above the surface at which the density or pressure if the atmosphere decreases by exactly 1/e or (2.718)-1 times (equal to 0.368). The scale height, usually represented by the variable H, depends on the strength of
Scale Height - Definition of Scale Height - NAAP
Scale height is a general way to describe how a value fades away and it is commonly used to describe the atmosphere of a planet. It is the vertical distance over which the density and pressure fall by a factor of 1/e.
scale height - Glossary of Meteorology
The height within which some parameter, such as pressure or density, decreases by a factor 1/e in an isothermal atmosphere. The term is most often used in an ionospheric context, but is equally applicable to the neutral atmosphere .
SCALE HEIGHT - Space Academy
The scale height is related to the temperature (T) and mean molecular mass (m) of the atmosphere by the formula H = kT/mg where k is Boltzmann's constant and g is the gravitational acceleration of the body.
Chapter 1: Atmospheric Basics – Atmospheric Processes and …
“Scale height” is denoted by H and represents an e-folding distance for the drop off of density in the atmosphere. Typically the value of H is around 8000 m. This means that density at 8 km is approximately 1/e (e=2.71828) of the value at the surface.
The Earth's Atmosphere - Case Western Reserve University
Scale height defines the distance over which the pressure drops by 1/e = 0.37 Scale height smaller for heavier atoms/molecules. Example: What is the scale height of the Earth's atmosphere?
The scale height, atmospheric surface density (in terms of Earth’s atmospheric surface density), and maximum elevation for Venus, Earth, and Mars are given in the table below. Use scale height to calculate
8.7: Scale Height in an Isothermal Atmosphere
where \( H=\frac{R T}{\mu g}\) is the scale height. It is large if the temperature is high, the gas light and the planet’s gravity feeble. It is the height at which the density is reduced to a fraction 1/e, or 36.8%. of its ground value.
scale height - Vaporia
Scale height is a measure of the decrease of something that falls off exponentially by height, specifically, the height over which it falls by a factor of e (~ 2.718). Examples can include:
