pollen in the atmosphere
2014-06-01 02:40:19

Marlene Cimons, National Science Foundation Researchers study water cycle and cloud formation and design computer algorithm models to understand impact In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that pollen particles were not as sturdy as they once thought, they have been rethinking their old assumptions. "Pollen can rupture and...

Rainbow-Like Feature Imaged On Venus For The First Time
2014-03-12 08:59:24

ESA A rainbow-like feature known as a ‘glory’ has been seen by ESA’s Venus Express orbiter in the atmosphere of our nearest neighbor – the first time one has been fully imaged on another planet. Rainbows and glories occur when sunlight shines on cloud droplets – water particles in the case of Earth. While rainbows arch across wide swathes of the sky, glories are typically much smaller and comprise a series of colored concentric rings centered on a bright core. Glories are...

Clouds Affected By Pollutants Could Enhance Climate Cooling
2013-05-06 05:35:43

redOrbit Staff & Wire Reports - Your Universe Online While manmade pollution and other natural emissions are often blamed for their role in global warming, new research from the University of Manchester suggests that they could actually play a role in cooling the world´s climate. According to the study, which has been published in the journal Nature Geoscience, those emissions could make clouds brighter. Clouds, the researchers explain, are comprised of water droplets that...

Certain Volatile Gases Found To Promote Cloud Formation
2013-02-05 09:20:34

April Flowers for redOrbit.com - Your Universe Online A new study from Columbia Engineering and the Georgia Institute of Technology shows — for the first time — certain volatile organic gases can promote cloud formation in ways atmospheric scientists have never before considered. The findings of this study were published online in the Early Edition of the Proceedings of the National Academy of Sciences (PNAS). "This is the first time gases have been shown to affect cloud...

Powerful "Overshooting Cloud Tops" In Cyclone Felleng Seen By NASA
2013-01-30 09:51:12

NASA NASA satellite imagery revealed that Cyclone Felleng is packing some powerful thunderstorms with overshooting cloud tops. An overshooting (cloud) top is a dome-like protrusion that shoots out of the top of the anvil of a thunderstorm and into the stratosphere. It takes a lot of energy and uplift in a storm to create an overshooting top, because usually vertical cloud growth stops at the tropopause and clouds spread horizontally, forming an "anvil" shape on top of the thunderstorms....

OH Radicals Causes Aging Of Organic Aerosols
2012-10-05 10:17:23

Climate models need to be updated Atmospheric aerosol particles have a significant effect on climate. An international team of researchers has now discovered that a chemical process in the atmosphere called aging determines to a major extent the concentration and the characteristics of aerosol particles. To date, this aspect has not been accounted for in regional and global climate models. In the Muchachas [Multiple Chamber Aerosol Chemical Aging Experiments] project, the team has not...

Undulatus Asperatus Clouds Seek Official Status
2012-09-20 19:06:49

Lee Rannals for redOrbit.com — Your Universe Online A new variety of cloud is attempting to be officially added to the classification system after first being discovered in 1951. Meteorologists and "cloudspotters" are looking to formally add undulatus asperatus clouds, or "agitated waves," to the official list of cloud species. The clouds look like a fluffy blanket that cover part or all of the sky. The United Nations' World Meteorological Organization (WMO) in Geneva has the...

Students Help NASA Validate Satellites With Cloud Observations
2011-11-16 05:57:54

In between recess, geography class and eating the lunch their moms packed, NASA scientists have found the time to help validate Earth-observing satellites. These scientists are the younger variety -- students in NASA's S'COOL project (Students' Cloud Observations On-Line), a worldwide effort to collect cloud observations from the ground. The students make observations like a NASA scientist and submit reports for their area to NASA. In return, the students receive a corresponding cloud...

Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions. The new study led by the National Center for Atmospheric Research (NCAR), is part of ongoing research that focuses on so-called hole punch and canal clouds that form when planes fly through certain mid-level clouds, forcing nearby air to rapidly expand and cool. This causes water droplets to...

Evaluating one way of how clouds can form. To understand this method it’s important to understand a few terms. The first one is Cloud Condensation Nuclei. The CCN can consist of anything from dust, dirt, salt anything that is floating in the air. The second thing is moisture. There must be moisture present in the atmosphere to condense on the CCN to form a droplet. Next step to the process is what is known as collision and coalescence. This is the process of many CCN’s running...
