Alan Buis, Jet Propulsion Laboratory and Kimm Fesenmaier, Caltech Of all the factors that influence Earth's changing climate, the effect that tiny particles in Earth's atmosphere called aerosols have on clouds is the least well understood. Aerosols scatter and absorb incoming sunlight and affect the formation and properties of clouds. Among all cloud types, low-level clouds over the ocean, which cover about one-third of the ocean's surface, have the biggest impact on the albedo, or...

Kathleen Haughney, Florida State University New research by a Florida State University geography professor shows that climate change may be playing a key role in the strength and frequency of tornadoes hitting the United States. Published Wednesday in the journal Climate Dynamics, Professor James Elsner writes that though tornadoes are forming fewer days per year, they are forming at a greater density and strength than ever before. So, for example, instead of one or two forming on a...

Los Alamos National Laboratory Scientists have uncovered key attributes of so-called “brown carbon” from wildfires. Scientists have uncovered key attributes of so-called “brown carbon” from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material’s warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the...

Susan Brown, UC San Diego Anomalous isotopes trace Earth’s ancient atmosphere, past El Niño events and future climate Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future. Eruptions of huge volcanoes, the disruptive weather pattern known as El Niño, and a fire season from hell each left distinctive chemical marks in layers of snow excavated near the South Pole, researchers from the...

Carol Rasmussen, NASA Earth Science News Team If you're reading this, there's a good chance that you or someone you know has been in a science fair. Chances are that your project did not lead directly to a collaboration with a scientist at NASA's Jet Propulsion Laboratory, Pasadena, California, and a paper in the professional journal Environmental Research Letters. Alice Zhai's project did. The 16-year-old Zhai, who will be a senior this fall at La Cañada High School near JPL in...

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...
