Global Warming Increases Tropical Rainfall Extremes
2012-09-18 07:18:50

April Flowers for redOrbit.com - Your Universe Online Extreme precipitation events in the tropics can come in many forms; thunderstorm complexes, flood-inducing monsoons and wide-sweeping cyclones like the recent Hurricane Isaac. Scientists expect global warming to intensify extreme precipitation, but the rate of intensification in the tropics remains unclear. A new study from MIT, published online this week in Nature Geoscience, gives an estimate based on model simulations and...

Summer Rain Triggered By Dry Soil
2012-09-13 04:48:56

April Flowers for redOrbit.com - Your Universe Online An international team of scientists and research groups released a study which suggests a strong correlation between summer rain storms and dry soil conditions. In short, summer rains are more likely over drier soils. The Centre for Ecology and Hydrology in the UK, the VU University Amsterdam, the Center of Meteorology CNRM in Toulouse, and the Vienna University of Technology collaborated on a detailed analysis of satellite data....

Brett Smith for redOrbit.com — Your Universe Online The forests that skirt high peaks have always been dependent on the accumulation of winter snowfalls that subsequently melt and provide valuable moisture down the steep mountain slopes. A team of scientists, led by University of Colorado-Boulder scientists Ernesto Trujillo and Noah Molotch, has investigated how the trends of rising temperatures and declining water availability have influenced these mountain forests over the past...

After the fall of the Soviet Union twenty years ago, water distribution in Central Asia became a source of conflict. In areas where summer precipitation is low, glaciers play an important role when considering the quantity of available water. The Tien Shan region is a prime example; mountain glaciers in this region contribute significantly to the fresh water supply in the arid zones of Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan, and Northwestern China. Like Switzerland, Kyrgyzstan...

Reign Of Acid Rain Is Far From Over
2012-07-26 05:46:01

New connection between climate change and acidification of Northeast's forests and streams Acid rain. It was a problem that largely affected U.S. eastern states. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients. New England's sugar maples were among the trees left high and...

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...

Weather Education - Orographic Thunderstorms
2013-01-13 09:40:16

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...
