Sentences with phrase «higher cloud layers»

First, the satellite can see actual low clouds only when higher cloud layers are not present.

The lack of absorption features means that GJ 1214 b can not have a diffuse hydrogen atmosphere unless it also has a high cloud layer that blocks the starlight from streaming through.

Not exact matches

The false colors represent the altitudes of the various cloud layers — blue being the highest and red being the lowest.

Observations by Akatsuki found a high speed equatorial current in the lower to middle cloud layer, though what drives it remains unexplained.

It's even more dramatic when a thin layer of high clouds is present.

These include a widening of one of the brown belts just north of the equator, which has spawned wave patterns throughout the northern hemisphere, both in the cloud layers and high above in the planet's stratosphere,» said Dr Fletcher from the University of Leicester's Department of Physics and Astronomy.

During the dry season, with no fog layer to reflect sunlight, the smaller cloud cover allows plants to receive much higher radiation, increasing evaporation and photosynthesis rates, another process missed by the GCMs.

While the large atmospheric pressure at the surface and the high altitude of the Venusian cloud layer appears to exclude the possibility of cloud - to - ground lightning (Gurnett et al. 2001; Aplin 2006), several authors have suggested that lightning discharges above, between or within clouds may occur (Borucki 1982; Russell & Scarf 1990; Gurnett et al. 2001).

In the second half of the talk I will present our recent studies of the young stellar population in W3 - AFGL333, located in a high density layer between the expanding W4 HII region and the W3 giant molecular cloud.

Based on the available data, the astronomers concluded that the planet's atmosphere is either a thin but dense layer rich in water steam or a thick layer of high clouds or hazes, similar to those seen in the atmospheres of Venus and Titan in the Solar System.

But they do at least have certain basic physical principles in their cloud representations — clouds over ice have less albedo effect than clouds over water, you don't get high clouds in regions of subsidence, stable boundary layers lead to marine stratus, etc..

A simple counterexample illustrates this: consider two massive cloud layers with equal shortwave albedo, one at high altitude, one at low altitude.

(Note that radiative forcing is not necessarily proportional to reduction in atmospheric transparency, because relatively opaque layers in the lower warmer troposphere (water vapor, and for the fractional area they occupy, low level clouds) can reduce atmospheric transparency a lot on their own while only reducing the net upward LW flux above them by a small amount; colder, higher - level clouds will have a bigger effect on the net upward LW flux above them (per fraction of areal coverage), though they will have a smaller effect on the net upward LW flux below them.

The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development

The towering clouds were so high that they punched through the troposphere (the lowest layer of the atmosphere where most weather occurs) and sent air loaded with ice crystals rushing into the stratosphere, a higher layer that normally contains very little moisture.

The rising zones, meanwhile, soar high into the atmosphere, and contain clouds of ammonia ice crystals that reflect sunlight, and block the view of the darker layers below, just like clouds here on Earth.

Composite imaging is an extremely useful tool for helping people understand the Earth — they allow researchers to capture certain features at higher resolution; reduce the obscuring effect of cloud coverage in certain areas; and overlay various data layers to help identify patterns and trends.

When solar activity is high and (under the GCR - cloud theory) cloud cover is low, a high amount of solar radiation reaches the oceans unblocked by clouds, where it penetrates and warms the upper ocean layer.

The energy released now heats the gas till it becomes an ionised plasma due to the high Temperature, the escape of this centraally generated energy to the suface of the «cloud», now a proto star will eventually stop the collapse as the outer layers also heat, and the outer plasma will become opaque to the EM radiation generted at the million degree buring interface.

Pooh, Dixie Erlykin and Wolfendale do specify that, relatively speaking, the greatest effect was seen in low cloud cover and mid cloud cover, and they use the f value for those levels in their calculations, but if CR affect higher layers dissimilarly so as to reduce the net effect that should be noted.

Rather than having a thin atmosphere and solid - and - liquid surface like Earth, Saturn is a gas giant whose deep atmosphere is layered with multiple cloud decks at high altitudes.

It is similar to cloud seeding, except at high altitudes, and is designed to produce thin layers of cloud.

Given that the NARR high - level cloud layer is situated above 350 mb, this latitudinal asymmetry is likely due to the positioning of the subtropical and polar jet streams.

Well, you can guess it based on the type of clouds — in zones of high pressure the dominant cloud type are the stratus family — thin, layered clouds, that absorb far less energy than cumulus clouds, and can dramatically increase albedo, therefore act as climate coolers.

The climate models with the mixed layer oceans underestimate both the subtropical low cloud cover and the high - latitude sea ice / surface albedo, and consequently have a smaller warming response to OHT.
