Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from March 14: A few snow showers remained over the Eastern Great Lakes, otherwise a good portion of the country saw high pressure and nice weather. The cold air did settle in over the Southeast as there were many late season frost and freeze advisories and warnings issued last night for this area. Big Story Weather Discussion for March...
Heavy rains have become more frequent in the upper Midwest over the past 60 years, according to a study from the University of Iowa. The trend appears to hold true even with the current drought plaguing the region, the study's main author says. The fact that temperatures over the country's midsection are rising, too, may be more than coincidence.The hotter the surface temperature, which has been the trend in the Midwest and the rest of the world, the more water that can be absorbed by the...
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from March 13: The storm system finally moved off shore over the Northeast, but it still brought rain showers to places in the Northeast. High pressure over the Southeast brought a cool evening to the South and Gulf Coast. High pressure over the Rockies kept a good portion of the West dry. A weak frontal boundary moved through the Northwest and...

Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from March 12: The storm system moved through the East Coast yesterday bringing rain showers to many places, while in the Great Lakes region people again saw more snowfall. High pressure began to slide through the Plains as well and this brought another bout with colder temps all the way back to the Gulf Coast. A weak clipper system moved through...
The Earth Institute at Columbia University A delay in the summer monsoon rains that fall over the southwestern United States and northwestern Mexico is expected in the coming decades according to a new study in the Journal of Geophysical Research. The North American monsoon delivers as much as 70 percent of the region's annual rainfall, watering crops and rangelands for an estimated 20 million people. "We hope this information can be used with other studies to build realistic...
Delay Could Affect Agriculture, Livestock, Desert Ecosystems A delay in the summer monsoon rains that fall over the southwestern United States and northwestern Mexico is expected in the coming decades according to a new study in the Journal of Geophysical Research. The North American monsoon delivers as much as 70 percent of the region's annual rainfall, watering crops and rangelands for an estimated 20 million people.

April Flowers for redOrbit.com - Your Universe Online One would not assume that cloud cover over Antactica's Southern Ocean could cause rainfall in Zambia or the tropical island of Java. New research from the University of Washington, however, finds that a phantom band of rainfall just south of the equator that does not occur in reality is caused by poor simulation of the cloud cover thousands of miles farther to the south. This illusionary band of rainfall is one of the most persistent...
NASA A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic’s ozone depletion tends to be milder and shorter-lived than the Antarctic’s. This is because the three key ingredients needed for ozone-destroying chemical reactions —chlorine from man-made chlorofluorocarbons (CFCs),...
April Flowers for redOrbit.com - Your Universe Online A new tree-ring study, led by the University of Arizona, reveals that long-term droughts in Southwestern North America often mean a failure of both summer and winter rains. This contradicts a long held belief that a dry winter rainy season is usually followed by a wet monsoon season, or vice versa. According to the new data, both summer and winter rains were sparse year after year during the severe, multi-decadal droughts occurring...

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 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 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...
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...
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...
