Sentences with phrase «rising updrafts»

Cirrus clouds — high - altitude clouds of ice crystals — typically form as a byproduct of the life cycle of cumulus towers created by rising updrafts of heated, moist air.

This argument hinges on the contention that more water vapor means greater density of water droplets in the active rising updraft of the storm clouds.

Not exact matches

That winged vision, rising on the updraft of an earlier time, has valiantly beat its course through fair and stormy skies until now, 70 years after The Christian Century was refounded, it still summons us to move forward and finish the Reformation.

This is because terrestrial hurricanes form when an inflow of air along the ocean surface sops up moisture and rises in a halo of updrafts to create towering columns of rain clouds.

The heat would rise, creating updrafts and quickly strengthening the storm.

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.

Clearly, these aren't the conditions to create thermal updrafts — rising pockets of hot air that hawks and vultures ride like elevators.

In the simulation, this caused a plume of warm, moist air to rise from the lake at a top speed of 194 kilometres per hour, similar to the updraft speed in thunderstorms on Earth.

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.

These little droplets are especially light and so it is easier for them to rise to higher levels of the cloud on thermal updrafts.

What this argument fails to consider is that the greater SST also produces a more vigorous updraft, so that the rising moist air has less time in which the collision / coalescence process can work before the air reaches the upper cloud layers where spontaneous ice nucleation takes place (at somewhere around -40 C, reached near the top of the troposphere).

«The latent heat is an important ingredient in fueling the updrafts that allow the towers to rise to such icy heights, so «in honor» of the role that latent heat plays, the towers are called hot towers,» explained Owen Kelley, a research scientist based at NASA's Goddard Space Flight Center.

So upon this cleansed - of - GHG planet Earth, how exactly would the atmosphere's temperature profile evolve toward a more nearly isothermal profile, in which rising thermal updrafts were weaker than in the present atmosphere?

This should give rise to stronger convective updrafts and more lightning.

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.

Convection is characterized by a circulation pattern of rising and sinking air masses, and the atmospheric vertical volume transport takes place through cells of updraft and subsidence; however, these may not be coherent or stable in time and space.
