Global Warming Cooled Down By Volcanic Eruptions
2014-02-25 04:32:25

[ Watch the Video: Global Warming Cooled By Volcanoes ] Lee Rannals for redOrbit.com - Your Universe Online Researchers at Lawrence Livermore National Laboratory report they have found that volcanic eruptions in the early part of the 21st century have cooled the planet. The total heat content of the ocean, along with global-mean temperatures at the surface of the planet and in the troposphere have shown relatively little warming since 1998. This “slow-down” has been the topic of...

OKLAHOMA CITY, Feb. 22, 2014 /PRNewswire/ -- Oklahoma Insurance Commissioner John D. Doak is encouraging support for House Resolution 2413, which would establish the Tornado Warning Extension Program. The resolution is aimed at funding a research program within the National Oceanic and Atmospheric Administration (NOAA) to extend the lead time for tornado warnings beyond one hour. "Protection of life and property is of utmost importance during severe weather events such as the ones we...

Tropical Cyclone Guito Exits The Mozambique Channel Seen By NASA
2014-02-22 07:04:21

NASA/Goddard Space Flight Center NASA's Terra satellite captured a visible image of Tropical Cyclone Guito as it exited the Mozambique Channel and moved into the open waters of the Southern Indian Ocean. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite captured a visible image of Tropical Cyclone Guito on Feb. 21 at 07:05 UTC/2:05 a.m. EST and took a visible image of the storm exiting the Mozambique Channel. The image showed...

NASA's Sees Extreme Rainfall From Tropical Cyclone Guito
2014-02-21 13:21:22

NASA/Goddard Space Flight Center Tropical Cyclone Guito has been a powerful rainmaker, and fortunately, data from NASA's TRMM satellite shows that the heaviest rainfall has occurred over the open waters of the Mozambique Channel and not over land. The Tropical Rainfall Measuring Mission or TRMM satellite had a look at tropical cyclone Guito in the Mozambique Channel on February 18, 2014 at 1525 UTC/10:25 a.m. EST. The early evening (local time) view occurred only about three hours...

Historic demonstration based on three years of research. Tampa, FL (PRWEB) February 20, 2014 One year ago today, researchers at the Insurance Institute for Business & Home Safety (IBHS) made history by creating the first-ever full-scale hailstorm in a controlled laboratory environment during a test demonstration at the IBHS Research Center in Richburg, S.C. “Replicating a hailstorm as closely as possible to what we observe in the field involved a great deal of creativity, scientific...

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...

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...
