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 .
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 ...
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 ...
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 ...
If the overshooting top is continuous, it's an indication of enhanced probability that the storm is a supercell, i.e. a rotating storm. [5] During a strong tornado, the overshooting top may roll or fold over as new activity climbs up the back while the front of the overshooting top collapses into the storm. During a long-track tornado, the ...
The National Weather Service offers storm spotting training session to the public throughout Central Indiana. Indiana tornado season is approaching. Here's how to help spot severe weather
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 ...
