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 .
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. Their area of cold cloud tops exceeds 100,000 square kilometres (39,000 sq mi) with temperature less than or equal to −32 °C (−26 °F); and an area of cloud top of 50,000 square ...
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 ...
The time a tornado is on the ground can range from an instant to several hours, although the typical time is around 5 to 10 minutes. ... It is possibly the most dangerous of "convective storm ...
Storm chasing – Traveling with the intent to observe tornadoes and other severe weather. Storm interaction; Storm merger; Storm relative environmental helicity (SREH) or storm relative helicity (SRH) Storm shelter; Storm spotting – The observation of severe weather by individuals trained in weather and reporting. Spotters can be stationary ...
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 .
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.
While there is no question that storm spotting has saved many lives and aided weather agencies greatly, there is concern that storm spotting may actually put individuals in danger. It is a common practice for many spotters to leave their vehicles or places of shelter to better observe, but this also places spotters in a situation where they can ...
