Calculated estimates of the electrization processes of the solid dielectric particles under consideration and the accumulation of a volume electric charge with them in the atmospheric cumulonimbus cloud
can be performed for the case of normal atmospheric conditions (air pressure is 1,013 x [10.
Forty years later, this basic mechanism is still the paradigm for how cumulonimbus clouds
affect the heat and moisture balances of the surrounding troposphere (though, of course, in high-resolution simulations, the mechanisms are resolved rather than parameterized; see, for example, Plant 2010 and Arakawa and Jung 2011).
, or thunderheads, extend well up into the atmosphere, as high as 5 to 10 miles.
The twister was likely to be a funnel cloud - condensed water droplets extending from the base of a cumulus or cumulonimbus cloud
For example, the larger size of many newer homes, especially those with few large trees around them, makes them easy targets for a fiery bolt from a cumulonimbus cloud
William Rankin was passing over a monstrous cumulonimbus cloud
when, at nine miles up, the engine of his F-8 fighter jet quit with a grating, rasping jolt.
A cumulonimbus cloud
occupying a volume of 1,000 cubic miles often weighs more than 1 million (1.
This was the question posed the last time I dared to venture there, nursing a wiffy pint of cumulonimbus cloud
quality, destined to be left unfinished amid the wash of ``gorrennie'' beggars, ``wannennie'' salesmen of quality odd socks, flamethrower lighters and prosthetic limbs and the general meffing and blinding being bandied across the bar.
As it continues to pile up, it may form a cumulonimbus cloud
or thunderhead, with a telltale anvil shape.
This storm came from highlevel cumulonimbus cloud
that developed over the Holme Moss peaks and tracked NE across the town, with 10mm of rain falling in just 30 minutes.
To detect the details of a cumulonimbus cloud
, we need ultra-short wavelength K-band radar, but these are extremely susceptible to attenuation and would pick up all clouds, creating a mess of distracting information on the radar.
They are connected to a towering cumuliform cloud or a cumulonimbus cloud
As a towering cumulonimbus cloud
approached from the north-east, I quickly headed to the highest point of the sea-cliffs, which commands superb views across Emard Bay and the mountains of Assynt.
We volunteers have no doubt that this is the work of the weather machine, and the cumulonimbus cloud
that hangs low over the park, darkening, but the tornados do not appear to be attached to the cloud, or to anything in particular, the tops of the funnels simply dissipating into warm air.
A tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud
or, in rare cases, the base of a cumulus cloud.
