Sentences with phrase «ice particle size»

Not exact matches

Professor Brilliantov from the University of Leicester's Department of Mathematics explained: «Saturn's rings are relatively well studied and it is known that they consist of ice particles ranging in size from centimetres to about ten metres.

The particles of rock and ice in these belts vary in size from the tiniest dust grain, smaller than a millimetre across, up to asteroid - like bodies many kilometres in diameter [2].

YOUTHFUL COMPANIONS Saturn's rings consist of water - ice particles — typically ranging in size from a few inches to many feet — that continually gather into clumps and drift apart again.

In particular, none of the hypotheses about their origin explain why individual ring particles, which range in size from hailstones to small boulders, average between 90 % and 95 % ice.

Aeolian deposition is responsible for sorting and transporting lithogenic matter (primarily sand - and clay - sized particles), containing microbial cells from the surrounding desert environments (soils, ephemeral streams, glaciers, etc.) onto the ice covers that range in thickness from 3 to 20 meters.

The disk, which we see edge on, contains rock and ice fragments ranging in size from objects larger than houses to grains as small as smoke particles.

Pollution decreases the size of cloud and ice particles and increases their lifespans, making clouds grow bigger.

For example, the instrument was part of a massive field campaign in northern Alaska aimed to improve our understanding of the relationship between particle size and composition and their ability to form warm and ice clouds.

However, since the rate the droplets grow by condensation is inversely proportional to the own droplet radius, other processes are needed to precipitation - size particles to form (collision - coalescence and ice - phase processes).

Jackson, R.C., G.M. McFarquhar, A. Fridlind, and R. Atlas, 2015: The dependence of cirrus gamma size distributions expressed as volumes in N0 - λ - μ phase space and bulk cloud properties on environmental conditions: Results from Small Ice Particles in Cirrus Experiment (SPARTICUS).

Cited is Mitchell et al. (2010), which detailed a method developed to remotely sense the concentrations of various sizes of ice particles.

The 12 - and 11 - µm ΔBT helps to distinguish between high, thick clouds and high, thin clouds by delineating cloud phase (ice or liquid water) and cloud particle size (small or large).

The authors of this book derived for the first time the expressions for the critical radius rcr and critical energy DFcr of the ice germs with simultaneous analytical dependencies on the temperature, saturation ratio, external pressure, and finite size of the freezing particle....

Using liquid and ice microphysics models reduces the biases in cloud optical thicknesses to ≲ 10 %, except in cases of mistaken phase identification; most of the remaining bias is caused by differences between actual cloud particle sizes and the values assumed in the analysis.

The precise balance of these opposing effects depends on time of day, time of year, altitude, size of the water droplets and / or ice particles, latitude, current air temperature, and size and shape.

These particles may owe their high ice nucleation onsets to their large sizes.

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.

Macke, A., P.N. Francis, G.M. McFarquhar, and S. Kinne, 1998: The role of ice particle shapes and size distributions in the single scattering properties of cirrus clouds.
