What Makes El Niño Taimasa Different From Normal El Niño?
2014-02-20 12:41:02

University of Hawaii During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa. The Samoans call the wet stench of coral die-offs arising from the low sea levels "taimasa" (pronounced [kai' ma'sa]). Studying the climate effects of this particular variation of El Niño and how it may change in the future is a team of scientists at the International Pacific Research...

NASA Sees Ragged Eye Develop In Tropical Cyclone Guito
2014-02-20 09:41:29

Rob Gutro - NASA NASA satellite data was an "eye opener" when it came to Tropical Cyclone 15S, now known as Guito in the Mozambique Channel today, Feb. 19, 2014. NASA's Aqua satellite passed over Guito and visible imagery revealed a ragged eye had developed as the tropical cyclone intensified. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Guito on Feb. 19 at 1140 UTC/6:40 a.m. EST as it...

Recent comments by President Obama and Mayor Garcetti of Los Angeles are misinformed about Californian drought, say Friends of Science, citing the historic evidence of mega-epoch droughts throughout the Medieval Warm Period. Global warming stopped naturally about 16 years ago; droughts are affected by the position of the jet stream and other natural factors according to scientific experts. Calgary, Alberta, Canada (PRWEB) February 19, 2014 Los Angeles Mayor Garcetti claimed the California...

NASA Satellite Image Shows California Experiencing Record Drought
2014-02-19 08:13:13

Lawrence LeBlond for redOrbit.com - Your Universe Online Much of the American West is suffering from a persistent dry spell with California seeing the worst of it. And the drought is so bad in California that it can be seen from space. Using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra and Aqua satellites, NASA scientists released an image detailing the severity of the conditions in California. The state’s mountains and vegetation cover...

CERES Satellite Data Paint A Grim Picture Of Arctic Surface Darkening
2014-02-19 07:03:42

Lawrence LeBlond for redOrbit.com - Your Universe Online Earth’s reflectivity (albedo) is on a much faster decline than previously estimated due to the retreat of sea ice in the Arctic Ocean. A key instrument incorporated on several NASA satellites has revealed significant data on this profoundly concerning issue. A team of researchers from University of California, San Diego’s Scripps Institution of Oceanography used data from the Clouds and Earth’s Radiant Energy System (CERES),...

Colder US Winters Due To Shifting Polar Jet Stream: Study
2014-02-17 12:39:08

[ Watch the Video: Blame The Jet Stream On Colder Winters ] Brett Smith for redOrbit.com - Your Universe Online Global warming skeptics have pointed to the unusually cold winter in parts of the United States this year as evidence against climate change. However, a new study from Rutgers University indicates that the unusually chilly temperatures in the Midwest and southeastern US are consistent with projections of permanent shifts in weather patterns caused by rising temperatures....

Climate scientist Judith Curry, science writer Joanne Nova and investigative journalist Donna Laframboise challenge the male-dominated global warming Goliaths in the climate science field with blunt, probing questions about the waning evidence of carbon dioxide as a climate “knob’; and questionable practices by various organizations. Friends of Science salute these women who are willing to take on the contentious, climate science establishment. Calgary, Alberta, Canada (PRWEB)...

Pineapple Express Brings Much Needed Rain To California
2014-02-12 14:08:54

[ Watch The Video: GOES-West Satellite Sees ‘Pineapple Express’ ] NASA A new animation made at NASA using imagery from NOAA's GOES-West satellite showed the "Pineapple Express" bringing much needed rain and snow to California from Feb. 7 to 9. A "Pineapple Express" is a low-level jet of moist air flowing from Hawaii to California, delivering a generous supply of precipitation. In this case, much-needed rain falls in central California, which was suffering from a severe drought....

NASA Sees High Thunderstorms In Tropical Cyclone Fobane
2014-02-12 13:27:27

NASA/Goddard Space Flight Center Tropical Cyclone Fobane was located southeast of Reunion Island in the southwest Indian Ocean when the TRMM satellite passed over and captured rainfall and cloud data on the storm. TRMM saw that despite Fobane weakening, there was still some punch left in a few of the thunderstorms within. The Tropical Rainfall Measuring Mission or TRMM satellite passed over Fobane on February 11, 2014 at 0035 UTC. Fobane was very small but contained a few powerful...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

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 - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
