Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate the billowy air masses. But Livermore scientists and international collaborators have developed a new tool that will help scientists better represent the clouds observed in the sky in climate models. Traditionally, observations from satellites infer the properties of clouds from the radiation field (reflection of sunlight back into space, or thermal...
New information on the role of insoluble dust particles in forming cloud droplets could improve the accuracy of regional climate models, especially in areas of the world that have significant amounts of mineral aerosols in the atmosphere. A more accurate accounting for the role of these particles could also have implications for global climate models. Cloud properties can have a significant impact on climate, yet the effects of aerosols like dust is one of the more uncertain components of...
Forest Service Southern Research Station (SRS) scientists recently used long-term data from the Coweeta Hydrological Laboratory (Coweeta) in Western North Carolina to examine the feasibility of managing forests for water supply under the changing weather conditions forecast for the future. Published in the September issue of the journal Ecological Applications, the analysis examines the interactions among changing weather conditions, forest management, and streamflow using long-term data...
The Tropical Rainfall Measuring Mission (TRMM) satellite captured rainfall and cloud data from Typhoon Roke as it rapidly intensified before making landfall in Japan earlier today. Typhoon Roke followed a looping path for five days while maintaining tropical-storm strength prior to intensifying to typhoon-strength at 12 UTC (8 a.m. EDT) on September 19, 2011. When the TRMM satellite flew over Typhoon Roke, it was in the process of rapidly intensifying from a Category 1 to 3 storm...
The new website whatishealthandsafety.co.uk has been rolled out to offer advice on snow control and winter safety products. Manchester, United Kingdom (PRWEB) September 19, 2011 The summer is now firmly behind us and as autumn gets well under way, one website is advising homes and businesses that now is the time to be preparing for the colder months – whether it’s to improve health and safety or to save money. According to whatishealthandsafety.co.uk, many people might not...
Water restoration provider suggests being proactive in protecting your home from the elements as colder weather begins to be felt across the country. All it takes are a few simple steps to ward off Old Man Winter. Atlanta, GA (PRWEB) September 19, 2011 With the official beginning of fall just days away, lower temperatures mean an entirely new environment for your home to exist in for the next five or six months, and environment that can lend itself to flood and water damage if not...
LEWISTON, Maine, Sept. 1, 2011 /PRNewswire-iReach/ -- After a wild year of roller coaster weather--record snowfalls, flooding, droughts, and extreme bouts of heat--the 2012 Farmers' Almanac is rolling out its newest edition and its long-range winter outlook. According to this 195-year-old weather-predicting publication, the winter of 2011-12 will be one of "Clime and Punishment," which means some parts of the country will get a very frigid winter; while others will be on tap for lots of...
Two of the most destructive natural disasters of 2010 were closely linked by a single meteorological event, even though they occurred 1,500 miles (2,414 km) apart and were of completely different natures, a new NASA study suggests. The research finds that the same large-scale meteorological event — an abnormal Rossby wave — sparked extreme heat and persistent wildfires in Russia as well as unusual downstream wind patterns that shifted rainfall in the Indian monsoon region and...
A Montana State University researcher who analyzed 100 years of data has found a significant link between extreme Montana weather and the ocean temperatures near Peru.Montanans who want to know what to expect from the weather should look to the Pacific Ocean in the fall or maybe find a way to chat with some Peruvian fishermen, according to Joseph Caprio, professor emeritus in MSU's Department of Land Resources and Environmental Sciences and former Montana State Climatologist.If the average...
Given the UK's obsession with the weather, it would seem obvious that the basic understanding of how low pressure systems evolve has been known for a long time. Instead, some of the biggest storms in the UK's history, such as the Great Storm of October 1987, did not fit this basic understanding.With groundbreaking research, Dr David Schultz, from The University of Manchester believes the way we learn about the weather is wrong and has been wrong for 90 years.Writing in the journal Bulletin of...

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...
Orographic thunderstorms are formed when the air is pushed up a mountain side. This type of thunderstorm is found only on the windward side of a mountain range. In the United States we would find these types of thunderstorms on the western slopes of the Rocky Mountains and also on the western slopes of the Appalachians. Things that make this thunderstorm important: First of all they only form in certain geographical places on the earth as mentioned above. But they can form anywhere in the...
The area in red in the above image has been experiencing winter weather which is quite rare to the region; also at this time many places are still seeing rain and snow. From the South African Weather Service, they are forecasting for the Eastern Cape “Very Cold with snow heavy at times.” The majority of the regions in red in the image are going to see more rain and snow today, and some places may see heavy snowfall. Looking at forecast models of the region they will continue to see...
November 2012: The area is going to see a warm start to the month as temps will average in the 60-70F range with a few days rising into the 80’s and also a few days in the 50’s possible. Precipitation on the whole will be around 2-4inches for the month; while there will be none in the form of snowfall. There will be a high chance for an overnight freeze during the month. December 2012: Temps will fall for the month of December as high temps will be in the 50-70F range during the...
January 2012: Started out dry as the area only received 1.06in of rainfall which is about .76in below normal leading to an annual deficit of .76in. February 2012: Followed in January’s footsteps as being dry again; the area got only .99in of rainfall which lead to the annual deficit becoming 1.01in. March 2012: The area received a nice welcoming 3.29in of rainfall on the month which is about 1.92in above normal and brought the annual amount back to a positive 1.08in. April 2012:...
