Now, a rain drop remain buoyant until it reaches a certain size, and cloud
with updrafts can have larger raindrops kept buoyant and rain rain may increase it's size falling.
Since lightning increases nonlinearly
with updraft strength, the net result is about a 5 % increase in lightning flash rate.
Not exact matches
Due to the heating of the surface in connection
with sufficient humidity, a warm
updraft is released in the atmosphere.
For nearly a century, scientists had assumed Jupiter's weather worked like Earth's,
with light zones forming around
updrafts just as white clouds condense around rising currents here.
Activity within the eyewall is closely connected to the hurricane's overall intensity,
with the vertical
updraft fed by an inward - spiraling, ocean - hugging wind whose average speed is the highest across the whole storm.
The sudden increase in lightning is one sign a normal storm is rapidly evolving into a supercell,
with a large rotating
updraft — or mesocyclone — at its heart.
«Then, if the flash rate suddenly jumps to at least twice the standard deviation of that running average, there is a high probability the
updraft in that cell has strengthened, a supercell is forming and severe weather is more likely
with that storm.»
Scientists know that storms
with a rotating
updraft on their southwestern sides — which are particularly common in the spring on the U.S. southern plains — are associated
with the biggest, most severe tornadoes and also produce a lot of large hail.
A low - altitude flow of warm, moist air from an ocean area combined
with a flow of cold, dry polar air high up creates maximum instability, which means that parcels of air heated near the surface rise rapidly, creating powerful
updrafts.
One promising alternative is to represent clouds using models
with grids that capture the cloud
updrafts and downdrafts based on principles of conservation of momentum and energy.
Hoping to catch some Halloween
updraft, Horns, starring Daniel Radcliffe, landed rather weakly in 11th place,
with # 396,000 from 379 cinemas, including # 95,000 in previews.
With the ability to create his own
updraft to soar over his foes and strike from above, the Rito champion would be a worthy and powerful addition to the roster.

Yuri Pattison also holds considerable UK curatorial
updraft,
with a major work the ideal (v. 0.1) presented as part of British Art Show 8, 2015 - 2017, and he was the recipient of the 2016 Frieze Artist Award, culminating in a major new commission Insights (crisis trolley).
The greater lesson: Cloud microphysics and cloud
updraft dynamics interact
with surface processes in very complex and unexpected ways which defy simple hypotheses.
Cumulus convection tends to occur episodically
with individual
updrafts.
A: Wind shear, changes in wind speed and direction
with elevation, gives a thunderstorm its spin in the form of rotating
updrafts called mesocyclones.
These coupled
with the increased intrusion of the tropopause into the stratosphere appears to cause a change in the saturated adiabatic proccess and allows a greater
updraft resulting in an increase in the fall distance of the condensensing water vapor resulting in high average winds and lower eye pressures.
Some convective
updrafts can be more than 100kts vertically —
with liquid water carried up to the tropopause where the air temperature is minus 40 deg or colder — and the water as it freezes releases latent heat — that is not in accordance
with Stefan Boltzmann.
Anderson and his colleagues start
with a new and unexpected observation, based on high - altitude flights and satellite measurements: powerful
updrafts from powerful summer thunderstorms can send moisture much higher into the stratosphere than anyone had thought.
In general, clouds
with more ice, and thus lower brightness temperatures, are more likely to produce lightning and to have moderate to strong
updrafts and precipitation.
When
updrafts are vigorous, water drops are easily carried above the freezing level and some collide
with fluffy ice crystals to make larger, denser ice pellets called graupel.
In the western U.S., the model predicts fewer storms
with strong
updrafts overall, but about 25 % more of the strongest storms (Fig. 3).
Kellogg sank RAND Corp's 1950s fallout prediction computer model by formulating it in terms of very wooden assumptions (a static mushroom cloud,
with particles unaffected by the central
updraft and the toroidal downdraft around the periphery), unlike the rival USNRDL «dynamic» or D - model of fallout, which allowed heavy particles to fallout while small ones were still rising.
When the gust front gets under the
updraft, it pulls up on the rotating air associated
with the gust front, stretching it out, and causing it to spin faster... Both the source of rotation of the mesocyclone and the tornado ultimately come from environmental vertical shear, but a tornado can actually sometimes spin in the opposite direction.
Re 68 (myself)-- of course, some tornados are not from supercells — or are not formed by the exact same mechanism; generally what is needed is an
updraft over a region of partly horizontal shear such as that associated
with a gust front — it could be a gust front from another storm... there are landspouts, gustnados, etc... these tend to be weaker then the supercell tornados, as far as I know (And I'm not entirely sure what defines a «landspout»; for that matter, if a supercell tornado moves over water, is it then a waterspout or is it still a supercell tornado... anyone?)
This large wind turbine employs the downwind rotor which «makes good use of the
updrafts in the locations
with mountains and hills.»
The motor is reversible, allowing homeowners to change the direction of the fan from downdraft mode during the summer to
updraft mode during the winter.Apache has an integrated LED light, covered
with Clear Holophane glass, eliminating the need for bulb replacement.
It's all a long way from the «chuck out your chintz» campaign, but here at Housetohome we're wondering if there might be some mileage in the Yeezy floating through the air
with Kardashian - Wests falling through a bracing
updraft.
