Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection (DMC). DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus , the latter producing thunderstorms associated with lightning and thunder .
Convective inhibition (CIN or CINH) [1] is a numerical measure in meteorology that indicates the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection. CIN is the amount of energy required to overcome the negatively buoyant energy the environment exerts on an air parcel.
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall , wind , hail , lightning , and possibly tornadoes .
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
A mesovortex is a small-scale rotational feature found in a convective storm, such as a quasi-linear convective system (QLCS, i.e. squall line), a supercell, or the eyewall of a tropical cyclone. [1] [2] Mesovortices range in diameter from tens of miles to a mile or less [3] and can be immensely intense.
The latent heat release from condensation is the determinant between significant convection and almost no convection at all. The fact that air is generally cooler during winter months, and therefore cannot hold as much water vapor and associated latent heat, is why significant convection (thunderstorms) are infrequent in cooler areas during ...
Mesoscale convective systems are thunderstorm regions which may be round or linear in shape, on the order of 100 kilometres (62 mi) or more across in one direction but smaller than extratropical cyclones, [2] and include systems such as tropical cyclones, squall lines, and mesoscale convective complexes (MCCs), among others. MCS is a more ...
Anvil shaped thundercloud in the mature stage over Swifts Creek, Victoria, Australia. There are two primary forms of atmospheric instability. [2] Under convective instability, thermal mixing through convection in the form of rising warm air leads to the development of clouds and possibly precipitation or convective storms.
