	Energy Citations Database (ECD) - Energy and Energy-Related Bibliographic Citations
		The ability of subtropical stratus low cloud cover to moderate amplify the tropical response to climate forcing such as increased CO{sub 2} is considered.
		Cloud radiative forcing over the subtropics is parameterized using an empirical relation between stratus cloud cover and the difference in potential temperature between 700 mb (a level that is above the trade inversion) and the surface.
		Stratus low cloud cover is found to be a negative feedback, increasing in response to doubled CO{sub 2} and reducing the tropically averaged warming in comparison to the warming with low cloud cover held fixed.

		Most clouds owe their existence to upward vertical motion of air, hence they are often associated with weather producing phenomena, such as fronts, troughs, and low pressure systems.
		Nimbostratus are often included in many texts as low clouds, but here they are considered multi-layer clouds because their vertical extent often goes well into the middle cloud region and these clouds often have even taller cumulonimbus clouds embedded within them.
		Cap clouds form when air containing water vapor is uplifted on the windward slide of the slope and reaches saturation producing liquid water cloud droplets and a cloud which can "cap" the summit.

	Polar Low Forecasting (Site not responding. Last check: 2007-11-02)
		For example, the "comma" cloud signature, is associated with vorticity advection in advance of the short wave and is one of the more recognizable features linked to the forcing and subsequent formation of polar lows.
		The spiraliform signature is characterized by bands of convective cloud elements curving inward towards the polar low’s center of circulation and marking development of the low beyond the cyclogenesis phase.
		A cloud-free or nearly cloud-free eye is a characteristic trait of mature polar low, indicating the presence of a low-level warm core within the low and potentially strong surface wind conditions.

	Low Cloud Product Description
		Reflecting solar radiation, low clouds and fog appear as white against darker land and sea surfaces on visible images.
		This is because low clouds and fog have a very similar radiating temperature as the underlying land or ocean.
		The evolution of low clouds and fog can be seen at times during a twenty-four hour period.

	Met Office: Low cloud facts
		Low clouds are usually made up of water droplets and have a base below 2,000 metres.
		Cumulus clouds are often said to look like lumps of cotton wool because they appear as white heaps of cloud.
		Stratocumulus clouds often appear as a white or grey sheet which can be seen in large patches or even cover the whole sky.

	UPDATE (Site not responding. Last check: 2007-11-02)
		One limit is to correct for this drift in the ISCCP cloud data, which results in a good correlation between ISCCP low cloud amount and cosmic rays over the full period of available data (1983-1998).
		During 1994 a substantial drop in low cloud amount over a relatively short period is seen, after which the correlation with cosmic rays weakens.
		While not a proof that the correlation still holds, it does indicate that the uncertainties in cloud amount for the period after 1994 are clearly too large at present to draw any conclusion on either the absence or presence of a correlation with the cosmic ray intensity.

		Abstract: The ability of subtropical stratus low cloud cover to moderate or amplify the tropical response to climate forcing such as increased CO 2 is considered.
		Cloud radiative forcing over the subtropics is parameterized using an empirical relation between stratus cloud cover and the difference in potential temperature between 700 mb (a level which is above the trade inversion) and the surface.
		This relation includes the empirical negative correlation between SST and low cloud cover, and is...

	UPPER LEVEL LOW - Cloud Structure In Satellite Images
		The cloud structure of an upper level low in the IR, VIS and WV images is indicative of the present stage of this life cycle (see Meteorological physical background).
		While the cloud structure in the IR image is restricted to the area of the torn off upper level trough, the WV features extend beyond this area indicating the humidity sources.
		In contrast to this the centre of the low is overcast by mostly low level cloudiness which appears white in the VIS and grey in the IR image.

	ISCCP D2 Cloud Products
		Clouds modulate the solar irradiance incident on the Earth's surface (the insolation) and this affects the productivity of plants both on land and in the water as well as the surface temperature and heat budget.
		The cloud detection component has four major steps, the first two were part of the C-series cloud product (Rossow and Garder 1993a), and the last two are new to the D-series.

	POLAR LOW - Cloud Structure In Satellite Images
		The cloud structure of a mature Polar Low is often a pronounced vortex with a (partly) cloud free eye.
		Clouds further away from the centre tend to be less bright which means lower cloud tops, caused by descending air motion.
		A decaying Polar Low is indicated by the disappearance of the cirrus cloud and the eye feature, lower cloud tops (less bright in IR images) and the disruption of the vortex.

		Lee-of-the-mountain cirrus or leeside cirrus is a multilayered CI cloud shield on the lee of a mountain chain.
		Clouds are due to deformation of the thermal gradient, and, therefore, vertical motions.
		Low clouds may be associated with the CCB ahead of the warm front.

	Cloud, fog and precipitation
		Cloud produced by frictional turbulence is not usually associated with precipitation except perhaps for drizzle from dense layers.
		The air in the centre of a low pressure centre, trough or heat trough is lifted by convergence, as is the air in the inter-tropic convergence zone.
		Cloud droplets tend to fall but their terminal velocity is so low, about 0.01 metres/sec, that they are kept aloft by the vertical currents associated with the cloud construction process, but will evaporate when coming into contact with the drier air outside the cloud.

		Clouds are categorized according to cloud top altitudes and their optical thickness as specified in this table.
		The increase low cloud amount however is from the optically thick low clouds, while the decreased middle and high clouds are from the optically thin clouds.
		Our next plan is to modify the CAM so that its basic cloud distributions, in particular the optically thick low clouds, become closer to ISCCP measurements, and then carry out similar climate change experiments to study the dependence of the cloud feedback on the model basic cloud climatology.

		The cloud that materialised 30 miles south of Washington on Wednesday morning was so dense it triggered radar monitors on the Domestic Events Network, intended to prevent a repeat of the September 11 attacks.
		As an anti-aircraft missile battery on the roof of a nearby building was raised to the fire position, a Black Hawk helicopter was scrambled to take a look, but saw nothing except some clouds, one of which turned out to be the suspected aggressor.
		Such false alarms are common, triggered by clouds, flocks of birds or private aircraft wandering off course, but the White House confirmed yesterday that this was not the first time since September 11 2001 that the president has taken refuge in the hi-tech bunker beneath the building, the Presidential Emergency Operations Centre.

	04 September 1997 -- Radiational Cooling, Fog and Low Cloud (Site not responding. Last check: 2007-11-02)
		Upslope flow around the western side of the high pressure combined with the radiational cooling to produce an extensive area of low cloud across the central Plains.
		Note how these areas of low cloud are not as evident (if at all) on the IR channel 4 product.
		In this case, surface observations over the central Plains indicated that the cloud ceiling heights were between 800 and 2600 feet over Kansas and Nebraska, and only one station actually reported fog.
