WASHINGTON, Nov. 8, 2013 /PRNewswire-USNewswire/ -- A new NASA-led study of "atmospheric river" storms from the Pacific Ocean may help scientists better predict major winter snowfalls that hit West Coast mountains and lead to heavy spring runoff and sometimes flooding. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Atmospheric rivers -- short-lived wind tunnels that carry water vapor from tropical oceans to mid-latitude land areas -- are prolific producers of rain and...

Atmospheric River Storms Could Help Predict Winter Snowfall
2013-11-08 15:18:12

Lee Rannals for redOrbit.com - Your Universe Online A new study says “atmospheric river” storms from the Pacific Ocean could eventually help scientists predict major winter snowfalls. Atmospheric rivers are short-lived wind tunnels that carry water vapor from tropical oceans to mid-latitude land areas. They are known to bring large quantities of rain and snow on California’s Sierra Nevada Mountains. Researchers studied how two of the most common atmospheric circulation patterns...

Report by DeWayne Cecil, PhD, for Bio Logic Aqua Research Founder Sharon Kleyne raises questions about long-term climate change and human health. Grants Pass, OR (PRWEB) November 07, 2013 Satellite observations over the last 40 years suggest a gradual change from snow to rain, especially at the beginning and end of the cold season globally, and at higher elevations over the Earth’s surface. That was one of the predictions in a recent White Paper by Climatologist DeWayne Cecil, PhD, for...

With this acquisition, AccuWeather will now offer highly accurate,...

Amazon Deforestation Could Mean Droughts For Western United States
2013-11-07 12:22:13

Princeton University In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires. The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal...

Heavy Rain Around Super-Typhoon Haiyan's Eye Seen By NASA
2013-11-06 13:34:22

NASA/Goddard Space Flight Center Super Typhoon Haiyan continues moving toward the Philippines, and when NASA's TRMM satellite passed overhead, it was very close to the island of Palau and packing heavy rainfall. Haiyan is now equivalent to a Category 5 Hurricane. The forecasters at the Joint Typhoon Warning Center or JTWC accurately predicted that Typhoon Haiyan would become a powerful category five typhoon with sustained winds estimated to be over 135 knots/~155 mph. On Nov. 6, a...

Warm Sea Surface Helped Strengthen Tropical Storm 30W
2013-11-06 11:15:11

NASA NASA's Aqua satellite passed over the South China Sea and revealed that warm sea surface temperatures and low wind shear enabled Tropical Depression 30W to strengthen into a tropical storm. NASA's Aqua satellite passed over Tropical Storm 30W on Nov. 5 at 0611 UTC/1:11 a.m. EDT as it was making its way west through the South China Sea. The infrared AIRS data provides valuable cloud top temperature data that indicates how high the thunderstorms are the make up the tropical cyclone....

Hurricane Sandy's Impact Measured By Flickr Photo Posts
2013-11-06 12:24:36

Lee Rannals for redOrbit.com - Your Universe Online Hurricane Sandy hit 24 states in Late October last year, decimating parts of New Jersey and its famous boardwalk, becoming the second-costliest hurricane in US history. Scientists have now measured the superstorm's impact by using pictures posted on photo-sharing site Flickr. Thirty-two million photos of the weather phenomenon were posted on Flickr between October 20 and November 20 2012. Researchers, publishing a paper in the journal...

LAVAL, QC, Nov. 5, 2013 /CNW Telbec/ - With winter fast approaching, now is the time for Canadians to get their winter-weather driving skills in high gear. Driving on icy, wet or snow-covered roads requires sharp winter driving skills, and a good set of winter tires. Michelin Canada is teaching Canadians the dos and don'ts of winter driving with important tips that aim to keep them safe on the road. The Michelin Winter Driving Academy (www.michelinwintercenter.com) is an...

NASA Eyes Tropical Depression 30W Affecting Central Philippines
2013-11-05 10:04:49

NASA/Goddard Space Flight Center Tropical Depression 30W formed and moved through Visayas, Philippines. NASA's Aqua satellite captured an infrared image of the depression that showed it had some potential for heavy rain while moving through the central Philippines. NASA's Aqua satellite passed over Tropical Depression 30W, known locally as "Wilma," on Nov. 4 at 0529 UTC/12:29 a.m. EDT/1:29 p.m. Philippines local time as it was moving through Visayas, central Philippines. The coldest...

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...

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...

Weather Education - Super-cell Thunderstorms
2013-01-13 09:51:18

In this lesson we are going to take a look at super-cell thunderstorms and what they mean and how they impact our daily lives. First, a super-cell thunderstorm is formed from a cumulus-nimbus cloud.  Super-cell thunderstorms are the most advanced form of thunderstorms known on earth. This is because these types of thunderstorms need so many things to come together in the atmosphere at the same time. The first thing they need is the warm moist air at or near the surface. Secondly, is...
