Scientists of the National Center for Atmospheric Research (NCAR) have identified a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The study was conducted in cooperation with the U.S. Department of Energy, NASA, and the National Science Foundation (NSF), which is NCAR's sponsor. NASA scientists helped guide the project and are involved in broader research in this area.
Data provided by the Tropical Rainfall Measuring Mission (TRMM) satellite has helped experts to analyze the unusual flash floods that affected territories from Oklahoma to Tennessee during the first two weeks of August 2013 causing at least two deaths and damages in hundreds of homes and other structures.
For more than a decade Earth-observing satellites have been scanning the surface of our planet searching for fires while scientists combine their space-based data to predict crucial fire behavior and therefore try to mitigate potential damages. In the western United States, California and Colorado, the 2013 wildfire season has started earlier than normal due to the favorable conditions for fire present in this area.
For over 40 years, Earth Day has been celebrated every year on April 22. It was first observed on April 22, 1970, when 20 million Americans took to the streets, parks and auditoriums to demonstrate for a healthy, sustainable environment
