Why does it take a long time for a temperature inversion to end?
temperature inversion, condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude. When temperature inversion occurs, cold air underlies warmer air at higher altitudes.
Temperature inversion, a reversal of the normal behaviour of temperature in the troposphere (the region of the atmosphere nearest the Earth's surface), in which a layer of cool air at the surface is overlain by a layer of warmer air. (Under normal conditions air temperature usually decreases with height.)
- Tax inversion, or corporate inversion, is the practice of relocating a corporation's legal domicile to a lower-tax country, while retaining its material operations (including management, functional headquarters and majority shareholders) in its higher-tax country of origin.
- What is an atmospheric inversion and how does it trap air pollution? An atmospheric inversion, also known as a temperature inversion, is a situation in which stable, cold air rests near the ground, with warm layers above. This situation reverses the normal conditions.
- Radiation inversions are the most common type of inversion. In some places, they occur almost nightly. Radiation inversions generally happen in places where it cools off a lot at night. During the night, the ground cools off, radiating the heat to the sky. Hence, an inversion.
Surface temperature inversions occur when air temperature increases with height from the ground surface, which is the opposite of what normally happens (i.e. the temperature profile is 'inverted'). This results in a layer of cool, still air being trapped below warmer air.
- Subject–verb inversion in English is a type of inversion where the subject and verb (or chain of verbs, verb catena) switch their canonical order of appearance, so that the subject follows the verb(s), e.g. A lamp stood beside the bed → Beside the bed stood a lamp.
- Because molecules or atoms of a solid are bound elastically to one another, the excess pressure results in a wave propagating through the solid. The acoustic impedance (Z) of a material is defined as the product of its density (p) and acoustic velocity (V).
- Acoustic impedance (Z) is a physical property of tissue. It describes how much resistance an ultrasound beam encounters as it passes through a tissue. Acoustic impedance depends on: the density of the tissue (d, in kg/m3) the speed of the sound wave (c, in m/s)
