These cosmic objects have intense clouds of radio emission that extend hundreds of thousands of light-years away from a central energy source located in an active galactic nucleus (AGN), or quasar.
Soon after coining the term "Asian brown cloud", Dr Ramanathan realised there were similar if less intense clouds over parts of Africa and elsewhere; the initials ABC, already used by researchers, were retrofitted to stand for "atmospheric brown cloud" (which also appeased some political sensibilities).Another reason for the increased interest in all this has less to do with science than politics.
The powerful front that brought gale-force gusts and intense clouds of dust to much of Iraq is likely to clear by today, and similar conditions should not return for perhaps a week or two, private and military meteorologists said yesterday.
For instance, among persons who returned to work after 9/11, 70% of those who had intense dust cloud exposure did not report heavy dust in their workplace (based on wave 2 question on damage to workplace).
In this analysis, we used intense dust cloud that resulted from the two collapsing buildings in the morning of 9/11 as the dominant acute respiratory related exposure and we found it to be significantly associated with asthma and non-neoplastic lung diseases.
And then a look of intense emotion clouds her face.
For Blow, there was another intense issue clouding his experience: He'd been sexually molested when he was 7, by an older male cousin.
About half of this show is devoted to the intense bout of cloud studies he did in 1821 and 1822, incredibly nuanced observations of nebuli color and behavior.
In particular, 9/11 related injuries were strongly predictive of angina/heart attack, while intense environmental dust cloud exposure on 9/11 and 9/11-related PTSD were predictive of non-neoplastic lung diseases.
Thunderstorm activity near the eyewall became more intense, and the cloud tops in the eyewall became much cooler; simultaneously, outflow away from the eye became much more symmetrical, both signs of an intensifying tropical cyclone.
