TRMM Satellite Looks At Rainfall In Developing Low Near Mozambique
2014-01-29 14:26:54

NASA/Goddard Space Flight Center The TRMM satellite flew above a System 91S, a tropical low pressure area, in the Mozambique Channel on January 28, 2014 at 1011 UTC/5:11 a.m. EST. TRMM data collected with this pass may be helpful in evaluating this low for possible tropical cyclone formation. An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown on the left overlaid on a visible/infrared image from TRMM's Visible and InfraRed...

Air pollution in China has exhibited noticeable changes over the past 30 years, shifting from point-source pollution (around factories and industrial plants) in the 1980s to urban pollution in the 1990s. Since the start of this century, air pollution has become increasingly regional and more complex. Recent research has indicated that the cooperative transition of SO2 and NOx into secondary aerosols (sulfate and nitrate) played a critical role in the haze pollution episode in China in January...

Asian Air Pollution In Hawaii Is Tied To Climate Variability
2014-01-28 12:48:57

Princeton University Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found that shifts in atmospheric circulation explain the trends in Hawaiian ozone pollution. The researchers found that since the mid-1990s, these shifts in atmospheric circulation have caused Asian ozone pollution reaching Hawaii to be relatively low in spring but rise significantly...

Say researchers from the Hebrew University, US and Australia The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers from the Hebrew University of Jerusalem, the US and Australia who have studied the issue and whose work which has just appeared in the journal Science. Indeed, one could say that the picture is a...

Earth's Climatic History Was Written In Dust
2014-01-25 05:28:19

April Flowers for redOrbit.com - Your Universe Online Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea. To geological history researchers, these inconspicuous mud samples are a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of...

Earth’s CO2 And Climate Stabilized By Ancient Forests
2014-01-24 12:38:58

European Geosciences Union UK researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilized over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU)....

redOrbit Meteorologist Joshua Kelly Weather Forecast for January 23, 2014 11AM: Arctic high pressure is sliding southward out of the Northern Plains creating a weak boundary ahead of it. Today’s mess will be ahead of this boundary. There will be snow showers over the Great Lakes and a winter mess over the Gulf Coast and Eastern Texas. The Western US will be dry and mild again today. 11PM: The boundary will hit the Gulf of Mexico tonight. Look for this to be the focus of a major...

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...
