The role of the hydrological cycle during abrupt temperature changes is of prime importance for the actual impact of climate change on the continents. In a new study published in Nature Geoscience online (January 19, 2014) scientists from the University of Potsdam, Germany and the GFZ German Research Centre for Geosciences show that during the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread...

redOrbit Meteorologist Joshua Kelly Weather Forecast for January 20, 2014 11AM: A weak upper level trough will slide through the Northern Plains providing some light snowfall for the region. High pressure over the Northern Gulf of Mexico will keep most of the Southeast and Gulf Coast dry along with the Southern Plains. High pressure over Montana will bring another shot of cold air southward into the region. Dry weather and high fire hazards continue in the West as the drought continues....

Global Warming Expected To Increase Extreme El Niño Events
2014-01-20 04:34:22

redOrbit Staff & Wire Reports - Your Universe Online A new analysis of rain patterns has revealed that extreme El Niño events, such as the 1983 heat wave that caused Australia’s Ash Wednesday bushfires, will double as the planet warms in the years ahead. “We currently experience an unusually strong El Niño event every 20 years. Our research shows this will double to one event every 10 years,” study co-author Dr. Agus Santoso, a professor at the University of New South Wales...

[ Watch the Video: Global Hawk Gets To Work In The Western Pacific ] redOrbit Staff & Wire Reports - Your Universe Online NASA has deployed their pilot-less Global Hawk research aircraft in the western Pacific in order to monitor changes to the upper atmosphere and discover how changes there are impacting the planet’s climate. The mission, announced by the US space agency on Friday, is part of their Airborne Tropical Tropopause Experiment (ATTREX) airborne science campaign....

NASA Sees Southern Pacific Birth Tropical Cyclone June
2014-01-17 14:50:22

NASA The tenth tropical cyclone of the Southern Pacific Ocean cyclone season was born today, January 17 as NASA's Aqua satellite captured infrared data on the storm as it became Tropical Storm June. NASA's Aqua satellite passed over Tropical Cyclone June at 02:41 UTC. The Atmospheric Infrared Sounder or AIRS instrument captured infrared data and temperature information about June, and it was used to create a false-colored image at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The...

NASA Tracks System 94S Over Western Australia
2014-01-17 13:47:29

NASA NASA's Terra satellite saw the System 94S, a tropical low, still holding together as it continued moving inland from the Northern Territory into Western Australia today, January 17. The tropical low pressure system known as System 94S took a more southern route than previously expected and moved into Western Australia today, January 17. System 94S is now expected to continue moving in a southerly direction according to the Australian Bureau of Meteorology or ABM. The MODIS or...

NASA Sees Birth Of Tropical Cyclone Deliwe
2014-01-17 13:19:51

NASA The tropical depression southwest of Madagascar on January 16 developed into a tropical cyclone early on January 17 as NASA's Aqua satellite passed overhead and captured its birth. When Aqua passed over newborn Tropical Cyclone Deliwe on January 17 at 10:55 UTC/5:55 a.m. EST  the MODIS instrument or Moderate Resolution Imaging Spectroradiometer took a picture of it. Deliwe was previously known as Tropical Depression 09S. In the MODIS image bands of thunderstorms stretched west...

US China Top Global Warming List
2014-01-17 12:44:07

Ranjini Raghunath for redOrbit.com - Your Universe Online In a finding that comes as little surprise, the United States and China were found to be among the top seven countries that contributed to global warming in the last century. The study, carried out by scientists at the University of Concordia, also added Russia, Brazil, India, Germany and the United Kingdom to that list. Taken together, these countries were responsible for up to 60 percent of global warming between 1906 and 2005,...

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...
