SAN FRANCISCO, Dec. 6, 2012 /PRNewswire/ -- In a recent study, atmospheric scientists from the National Center for Atmospheric Research in the US, and the Universities of Manchester, Leeds and Edinburgh, UK, found that cooling ocean surfaces by brightening clouds with a sea-salt spray mist ("Marine Cloud Brightening") could reduce the intensity of hurricanes. It is possible that the largest hurricanes and hybrid storms could be prevented, saving billions in damage and preventing the...

Forest Ecosystems Impacted By Climate Change
2012-11-29 12:04:30

April Flowers for redOrbit.com - Your Universe Online Off the southern coast of California, the fog rolls in over Santa Cruz Island coating the needles of the Bishop pines with moisture. Water drops form on the needles and roll down to fall to the forest floor, happening over and over on every needle of every tree. The forest ecosystem depends on this fog drip to stay alive. Bishop pines are thought to have proliferated all along the West Coast of the US and Mexico thousands of years...

Foggy Perception Causes Us To Slow Down

Max-Planck-Gesellschaft Max Planck scientists show that, contrarily to what was previously believed, speed is overestimated in fog Fog is an atmospheric phenomenon that afflicts millions of drivers every day, impairing visibility and increasing the risk of an accident. The ways people respond to conditions of reduced visibility is a central topic in vision research. It has been shown that people tend to underestimate speeds when visibility is reduced equally at all distances, as for...

Sharp Ice Peaks Formed From Freezing Water Droplets
2012-10-05 08:01:01

Researchers at the University of Twente, in the Netherlands, placed water droplets on a plate chilled to -20 degrees Celsius and captured images as a freezing front traveled up the droplet. The photos are published in the American Institute of Physics' (AIP) journal Physics of Fluids. The approximately 4-millimeter diameter droplets took about 20 seconds to freeze. During the final stage of freezing, the ice drop developed a pointy tip, as can be seen in Figure 1d. The effect, which is not...

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

The map above shows our dew-point temperatures which is an important temp when it comes to weather. The dew-points help us determine how much moisture is in the atmosphere. If we look at the circle placed over Southern Mississippi we can see temps in the Mid 70’s. That is considered to be very saturated and humid type of weather. When you walk outside it feels very uncomfortable. While if we look back in Nevada we see 15, this is more respectful of being very dry air. This type of air also...

The Heat Wave Of The Central United States
2012-06-26 06:00:45

So why is there so much heat and humidity rising up into the Northern Plains creating a surge of hot weather? The answer is in the weather map above. If we look over Lake Michigan we see an area of High pressure which has a clockwise flow over the region. So places on the East are having cooler weather as they are getting the air from Canada pushing down towards them. North Dakota into the Gulf Coast are on the back side of the high so there air is coming from the Gulf of Mexico. If...

Water vapor (aqueous vapor) is the gaseous phase of water. It is one stage of the water cycle of our planet. Water vapor is formed from either evaporation or heating of liquid water, or from the sublimation of ice. In nature, water vapor is continuously produced by evaporation and removed by condensation. Along with carbon dioxide and methane gas, water vapor is one of the greenhouse gases. The release of water molecules from liquid water is considered evaporation. The transition of these...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
