Plants Are Natural Air Conditioners
2013-04-29 10:10:18

Brett Smith for redOrbit.com - Your Universe Online It has long been understood that plants are able to mitigate the forces of climate change by absorbing carbon dioxide from the air. However, a new study adds another dimension to the role played by plants in curbing global warming by showing that they also“¯emit gases that assist in cloud formation and atmospheric cooling. According to the study, which was recently published in the journal“¯Nature...

Microorganisms In Sea Spray Alter Ability Of Ocean To Seed Clouds
2013-04-23 11:09:06

April Flowers for redOrbit.com - Your Universe Online The ability of sea spray to form clouds over the ocean is influenced by ocean biology which alters the chemical composition of the spray. A team of scientists from the University of California, San Diego, is using a new approach to study tiny atmospheric particles called aerosols. These aerosols can influence climate by absorbing or reflecting sunlight and seeding clouds. "After many decades of attempting to understand how the ocean...

Changing Seasons On Titan
2013-04-12 07:40:24

April Flowers for redOrbit.com - Your Universe Online The latest sign that the change of seasons has started a cascade of radical changes in the atmosphere on Titan is an ice cloud taking shape over the south pole. This type of cloud, made from unknown ice, has long hung over the north pole. According to observations by the composite infrared spectrometer (CIRS) on NASA's Cassini spacecraft, the northern cloud is now fading. "We associate this particular kind of ice cloud with winter...

Noctilucent Clouds Observed By NASA Sounding Rocket
2013-04-04 14:55:35

NASA A constant stream of space debris flows toward Earth from the rest of the solar system. Large meteors can sometimes survive the intense friction and heat upon entering Earth´s atmosphere, but by and large the meteors evaporate and reform into tiny particles that are left to whiz through the atmosphere. Such particles are so light and so ubiquitous that scientists refer to them as smoke. Tracking how this smoke swirls around Earth has implications for understanding weather and...

Greenland's 2012 Record Ice Melt Due To Thin Cloud Cover
2013-04-04 11:15:46

April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

California Precipitation Impacted By Saharan Dust
2013-03-02 06:16:19

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of California, San Diego (UCSD) and the National Oceanic and Atmospheric Administration (NOAA) have demonstrated for the first time that dust and other aerosols from one part of the world can influence rainfall in regions thousands of miles away. The study is part of the CalWater field campaign — an initiative funded by the California Energy Commission and designed to help states in the...

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...

Weather Education - Orographic Thunderstorms
2013-01-13 09:40:16

Orographic thunderstorms are formed when the air is pushed up a mountain side. This type of thunderstorm is found only on the windward side of a mountain range. In the United States we would find these types of thunderstorms on the western slopes of the Rocky Mountains and also on the western slopes of the Appalachians. Things that make this thunderstorm important: First of all they only form in certain geographical places on the earth as mentioned above. But they can form anywhere in the...

Weather Pack For July 30, 2012
2012-08-01 12:22:59

Weather Pack is our way to envision what is happening with the weather and create a weather forecast for a certain area of the United States. Today’s focus is on Southwest Mississippi along the Mississippi River. On the left side we have a Skew-T which is used to help us determine what is happening in the upper levels at our forecast location. On the right side is our morning satellite image; both of these features are important to creating an accurate forecast. The Skew-T will show...

Surface Analysis Features
2012-09-03 16:09:19

The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such as cumulus or stratus. The second is the black circle found in the Dakota’s. Here we are...

Cumulus-nimbus Clouds
2014-01-11 00:00:00

The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development vertically. The storm on the right has not felt the upper level winds yet, that is why it lacks the...
