Sentences with phrase «more ice particles»

In colder years, more ice particles will freeze, allowing more chemical destruction of the ozone layer.

Not exact matches

The study notes that narrowing down that percent range requires particle accelerator experiments on water ice to more accurately gauge the number of chemical reactions that result per unit of energy deposited by cosmic rays and solar energetic particles.

Measurements of salt particles in ice cores suggest that storminess rose toward the end of the occupation, perhaps making voyages to hunt and trade walrus ivory even more dangerous.

«Lightning is caused by charge separation within clouds, and to maximize charge separation, you have to loft more water vapor and heavy ice particles into the atmosphere,» he said.

To help get their technology into drug companies» hands more quickly, DeSimone and his colleagues have built a device that make different - shaped nanoparticles in bulk using molds that pop out these particles like so many ice cubes.

It also would be far easier to get a water sample from Enceladus, which has plumes of water vapor, ice and particles shooting more than 300 miles off its surface, than from other moons, such as Jupiter's Europa, where a massive ocean is believed to be buried beneath a thick icy crust.

Recent research shows that there is high microbial activity on glacial surfaces (Anesio et al., 2009), some associated with pigmented algae, which absorb significantly more light than local inorganic dust particles on the Greenland Ice Sheet (GrIS)(Lutz et al., 2014).

By modifying dust particles in the laboratory to mimic this process, the team was able to measure their cloud - ice - forming potential, discovering some conditions are more favorable than others.

Much more interesting are the three distinct types of mineral flow across the landscape, produced by the movement of ice - rich material, landslides or blankets of ejected particles following impact into ice - rich material.

Ice particles are a much more complex problem, with five different ways the particles can form.

Using magic during combat also feels lackluster: unleashing an icy bolt to freeze enemies doesn't feel like you're doing much more than throwing an ice - cube at someone who mildly annoyed you, while setting foes alight with your Nova attack involves you creating what looks like a pile of gellatine at your feet before unleashing the attack which doesn't so much set fire to enemies as generate some weird particle effects.

An example of this kind of surprise happened in relation to the Antarctic ozone hole, where unexpected chemistry on surfaces of ice particles lead to much more efficient destruction of ozone in the polar vortex than had been expected, making an existing concern into a serious problem.

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

In addition, once snow cover melts completely it often reveals underlying ice that has been darkened by dust and other particles, whose surface absorbs more solar energy, promoting heating.

By seeding them with substances like bismuth tri-iodide, which cause water to form into ice particles, the hope is to reduce the water vapour and allow more radiation to escape.

The new study quantitatively assessed how surface ice algae contribute to darkening of the ice sheet, and found the algae reduce the ice sheet's albedo significantly more than non-algal materials, like mineral particles and black carbon.

This cooling is caused by the fact that that, as climate warms, clouds made of large ice particles are replaced by clouds made of more numerous and smaller water particles that reflect more solar radiation.

That is, more dust creates heavy ice particles in high clouds that rain down and ultimately reduce high cloud amounts.
