A column of air is potentially unstable when the equivalent potential temperature is decreasing even if there is an increase of potential temperature. But potential instability as such is not …

2024年3月29日 · The state of an unsaturated layer or column of air in the atmosphere with a wet-bulb potential temperature (or equivalent potential temperature) that decreases with elevation.

2000年12月1日 · 4. Potential instability. As discussed in the previous section, the inability of the lapse-rate definition of conditional instability to ascertain unambiguously parcel stability led to …

Convective (also called potential) instability occurs when dry mid-level air advects over warm and moist air in the lower troposphere. Convective instability is released when dynamic lifting from …

2018年5月14日 · potential instability (convective instability) Atmospheric condition in which otherwise stable air would become unstable if forced to rise, e.g. over high ground, thereby …

In meteorology, instability can be described by various indices such as the Bulk Richardson Number, lifted index, K-index, convective available potential energy (CAPE), the Showalter, …

• When EPV < 0, potential symmetric instability (PSI) is present. • However, EPV also is < 0 when there is convective instability; thus, you must see if the lines of 2 e (on a cross-section) are …

The most immediate cause of potential instability is North Korea, which now poses not just a conventional military threat to South Korea, but also a nuclear threat to all of Asia, as well as …

Instability is also called as malfunctioning of the flow in microchannels. Instability in microchannel may cause several problems such as vibration, problems of system control, thermal fatigue …

Atmospheric condition in which otherwise stable air would become unstable if forced to rise, e.g. over high ground, thereby reaching its saturation point. Large cumulus with much precipitation …
