Thunderstorms always mean rain or snow, showers (SH), and cumuliform
For example, the phrase "pendant from a cumuliform
cloud" from the AMS may be a technically accurate and important part of the definition, but for purposes of hazard planning this detail may not be important.
Tower--A clearly defined cumuliform
part of the storm that contains the updraft.
Consider the precipitation types which are associated with an unstable air mass: showers and thunderstorms, which by definition fall from cumuliform
Just like in the case of Virginia and Florida, the warm sector is dominated mostly by tropical air, lots of cumuliform
clouds, warm temperatures, and low densities.
And behind the front, if fresh cold air is crossing over warm terrain, it will produce lots of shallow cumuliform
clouds, though there is enough large-scale subsidence where they tend to flatten out rather than grow into deep showers.
With a cold advection scenario, lift is stronger and cumuliform
clouds are more likely to occur, with small areas of deep, intense icing.
This type of weather is not particularly dangerous, and with the air mass being unstable the result is cumuliform
clouds, intense showery precipitation, and good visibility outside the rain or snow showers.
Some of the remaining 20 percent of these icing reports are due to convective icing in vertically-developed cumuliform
Even with a satellite weather receiver, staying clear of turbulent and potentially icy cumuliform
clouds is a stretch when you can't see them (except when they're lit up by all that lightning).
The LCL approximates the bases of cumuliform
clouds and is drawn on the Skew-T as a black, horizontal bar.
The rising air can produce cumuliform
clouds, which can grow into cumulonimbus clouds under the right conditions.
