    In 2013... the vast majority of worldwide climate indicators... greenhouse gases... sea levels... global temperatures, etc... continued to reflect trends of a warmer planet... according to the indicators assessed in the State of the Climate in 2013 report... released online less than 2 weeks ago by the American Meteorological Society. Scientists from NOAA’s National Climatic Data Center in Asheville, N.C... served as the lead editors of the report.

    It's the dog days of summer... and the chill of an air conditioned room is a welcome respite from the heat! But cranking up the AC can increase your home energy use…and your energy bills. Two-thirds of U.S. homes have air conditioners and homeowners collectively spend 11 billion dollars each year to power them!

    NASA embarked last week on a coordinated ship and aircraft observation campaign off the Atlantic coast of the United States... an effort to advance space based capabilities for monitoring microscopic plants that form the base of the marine food chain. Phytoplankton are tiny ocean plants that absorb carbon dioxide and deliver oxygen to Earth’s atmosphere.

    The radar signature on the left… known as a "roost ring”… occurs as birds leave their roost and fly into the air. The roost ring expands until the birds begin foraging after dispersing. Often… just before sunrise…you might notice a curious doughnut pattern has appear over locations on doppler radar imagery. This roost ring occurs when the radar beam detects thousands of birds simultaneously taking off.

  • GPM Satellite Sees First Atlantic Hurricane

    GPM Satellite Sees First Atlantic Hurricane

    The Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Arthur five times earlier this month… between July 1 and July 5. Arthur was the first tropical cyclone of the 2014 Atlantic hurricane season. GPM began its prime mission on May 29… just in time for the hurricane season. The five GPM passes over Arthur are the first time a precipitation-measuring satellite has been able to follow a hurricane through its full life cycle.

    Did you know that a typical city block generates more than five times as much rainwater runoff as a forested area of the same size? This is because rooftops and pavement don’t allow water to soak into the ground like forests… wetlands and grasslands do. Instead… rainwater runs off pavement into the nearest storm drain… where it’s transported to local streams… rivers and eventually the ocean.

    Hopefully you agree… weather forecasts are usually fairly reliable. Meteorology (the study of the atmosphere and weather phenomena) has made steady progress since the mid-1900's. Much of the improvement in weather forecasting has come about because of the development of forecasting software… computer programs that enable supercomputers to peer into the future more and more accurately.
