Sentences with phrase «when ice particles»

Lightning results from the electrical fields that are created when ice particles in clouds rub together.

Storm clouds become electrified when ice particles collide with each other and with unfrozen droplets in the cloud.

Not exact matches

When high - energy ultraviolet light from the central star strikes a clump of dust and ice grains, it drives electrons off the particles.

But if scientists are able to gain a deeper understanding of which dust particles best form ice and which don't, they may be able to maximize precipitation when clouds do form and stave off future droughts like the one that has beset California recently (ClimateWire, Aug. 4).

Much of the dust deposit east of the Rockies arrived in the last ice age, which ended some 11,000 years ago, when particles that had been ground up and transported by glaciers were deposited by meltwater streams.

Intermittent phases of boiling, similar to what happened when Vinalia Faculae formed, may have occurred during this process, littering the surface with ice and salt particles that formed the Cerealia bright spot.

When the glacier starts to retreat, the frontal moraines are no longer protected by the ice, and a sort of «geological chronometer» is triggered, as the rocks begin to accumulate beryllium - 10 and helium - 3 produced by particles resulting from cosmic rays.

When neutrinos pass through ultra-clear-blue ice, the collision produces a particle — called a muon — that radiates blue light.

They're buried deep down in the ice, but they register the flashes of light that emitted when neutrinos interact with an atom and produces a new particle called a muon as the moon — muon travels through the ice, that's what lights it up.

One wouldn't think of ice particles burning up when they hit the atmosphere, but that is what happens?

When a neutrino collides with an atomic nucleus, a new particle called a muon is produced, which emits a faint blue glow in the transparent ice that the DOMs can detect.

Urine that it vented also left a residue when tiny particles hit the craft's panels, so Lorenz suggests that future missions to Enceladus could look for signatures of life if similar residue is found in the minuscule dents left on a detector by ice grains from the plumes.

Researchers have been fascinated with Enceladus since July 2005, when Cassini revealed plumes of ice particles and water vapour shooting out from the moon's south pole.

It is theorized that the process may be similar to what happens on comets, when water vapor lifts tiny particles of dust and ice off the surface.

The particles generated in this region can even reach Antarctica when they are transported by the wind (Gassó et al., 2010) and contribute to ice particles formation.

Understanding how dust particles are affected by each type of pollution will shed light for researchers to account for all types of pollution when computing which particles may form ice crystals in cold clouds.

In one sentence: Researchers at Pacific Northwest National Laboratory found that when miniscule particles of airborne dust, thought to be a perfect landing site for water vapor, are modified by pollution, they change cloud properties via ice crystal number concentration and ice water content.

Scientists are working to understand their underlying processes, such as which particle surface properties encourage or discourage ice formation, called nucleation, so they can accurately simulate how, where, and when clouds are formed.

As this water moves through rocks, it dissolves salt compounds and pushes through fractures in the overlying ice to form reservoirs closer the moon's surface, where it is expelled into space when the outermost layer of the crust cracks open and the resulting depressurization of these reservoirs causes water vapor and ice particles to shoot out in the observed plumes.

When the jeep drag you around the river, those small particles of ice can hit the face pretty hard.

When the particles settle out in these regions, the black carbon makes snow and ice darker, which in turn warms the ice.

Wendler found that more than 10,000 ice particles per second pass through a square inch when the katabatic winds are very strong.»

Soot particles absorb the sun's heat and melt the ice when they settle on glaciers.

It's a problem for the climate because the black soot particles are just the right color to absorb heat from the sun, either in the upper atmosphere or when it settles back down to earth on Arctic snow and ice (when soot - free, the polar ice caps reflect a tremendous amount of light and heat back into Space, helping keep the planet cool).

Typical temperature - supersaturation regions can be identified for the «onset» of ice nucleation of these different particle types, but the various particle sizes and activated fractions reported in different studies have to be taken into account when comparing results obtained with different methodologies.
