NOAA Hurricane Season Outlook|
May 26, 2013 | NOAA
“NOAA’s 2013 Atlantic Hurricane Season Outlook indicates that an above-normal season is most likely, with the possibility that the season could be very active. The outlook calls for a 70% chance of an above-normal season, a 25% chance of a near-normal season, and only a 5% chance of a below-normal season.
Based on the current and expected conditions, combined with model forecasts, we estimate a 70% probability for each of the following ranges of activity during 2013:
– 13-20 Named Storms
– 7-11 Hurricanes
– 3-6 Major Hurricanes
Quoted from the NOAA Hurricane Season Outlook.
Spring 2012 Earliest on Record|
May 22, 2013 | USGS
“March 2012 set records for warm temperatures that promoted early leafing and flowering across large areas of the United States.” Quoted from the USGS press release.
Warm Spring Temperatures and Western Water Supplies|
May 17, 2013 | USGS
“Warmer spring temperatures since 1980 are causing an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America. [...] Runoff from Rocky Mountain winter snowpack accounts for 60 to 80 percent of the annual water supply for more than 70 million people living in the western U.S.

How Cirrus Clouds Form|
May 9, 2013 | Oregon State University
“Researchers studying the origin of cirrus clouds have found that these thin, wispy trails of ice crystals are formed primarily on dust particles and some unusual combinations of metal particles – both of which may be influenced by human activities.” Quoted from the Oregon State University press release.
Diamond Dust over Saskatoon|

The Earth Science Picture of the Day for April 29th was “diamond dust” glowing from reflected natural light and city lights outside of Saskatoon, Saskatchewan, Canada.
Above-Average Probability for Major Hurricanes
Hurricane Sandy (NOAA image)
April 15, 2013 | Colorado State University
“We anticipate an above-average probability for major hurricanes making landfall along the United States coastline and in the Caribbean. Coastal residents are reminded that it only takes one hurricane making landfall to make it an active season for them, and they need to prepare the same for every season, regardless of how much or how little activity is predicted.” Quoted from the Colorado State University press release.
Low Arctic Clouds and Ice Sheet Melting|
April 8, 2013 | National Science Foundation
“Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point, according to a new study by scientists funded by the National Science Foundation and at the National Oceanic and Atmospheric Administration.” Quoted from the NSF press release.
Tropical Storm Tim|
March 19, 2013 | NASA Earth Observatory
“Tropical Storm Tim formed over the Coral Sea on March 13, 2013, and remained off the coast of northeastern Australia for the next four days. The Moderate Resolution Imaging Spectroradiometer on NASA’s Terra satellite captured this natural-color image of Tim on March 17. Although lacking a distinct eye, Tim still had the spiral shape characteristic of strong storms.” Quoted from NASA’s Earth Observatory image release.
Clouds and the Arctic Climate System|
March 13, 2013 | CIRES @ University of Colorado at Boulder
“Clouds are a critical element of the climate system, especially in the Arctic where surface energy budgets and precipitation can have dramatic impacts on the fate of sea ice and ice sheets.” Quoted from the Cooperative Institute for Research in Environmental Sciences press release.

Black Carbon in Snow and Climate Change|
March 5, 2013 | Cooperative Institute for Research in Environmental Science
“Black carbon particles in snow are larger than expected [...] this finding suggests that the warming produced by black carbon in snow could be currently overestimated by as much as 30 percent.” Quoted from the CIRES press release.
Third Van Allen Belt Discovered|
March 3, 2013 | NASA
“Since their discovery over 50 years ago, the Earth’s Van Allen radiation belts have been considered to consist of two distinct zones of trapped, highly energetic charged particles.” The accidental discovery of a third belt will require a rewrite of textbooks. Quote from the NASA press release.
How Atmospheric CO2 Levels Might Change Snowfall
February 27, 2013 | Princeton University
“A new climate model predicts an increase in snowfall for the Earth’s polar regions and highest altitudes, but an overall drop in snowfall for the globe, as carbon dioxide levels rise over the next century.” Quoted from the Princeton University press release.
Is the Ozone Layer Recovering?|
February 17, 2013 | European Space Agency
“Satellites show that the recent ozone hole over Antarctica was the smallest seen in the past decade. Long-term observations also reveal that Earth’s ozone has been strengthening following international agreements to protect this vital layer of the atmosphere.” Quoted from the European Space Agency press release.
Saturn Storm Chokes on its Own Tail|
January 31, 2013 | NASA
“In a new paper that provides the most detail yet about the life and death of a monstrous thunder-and-lightning storm on Saturn, scientists from NASA’s Cassini mission describe how the massive storm churned around the planet until it encountered its own tail and sputtered out. It is the first time scientists have observed a storm consume itself in this way anywhere in the solar system.” Quoted from the NASA press release.

National Climate Assessment|
January 25, 2013 | U.S. Global Change Research Program
“Climate change is already affecting the American people. Certain types of weather events have become more frequent and/or intense, including heat waves, heavy downpours, and, in some regions, floods and droughts. Sea level is rising, oceans are becoming more acidic, and glaciers and arctic sea ice are melting. These changes are part of the pattern of global climate change, which is primarily driven by human activity.” Quoted from the Executive Summary of the Federal Advisory Committee Draft Climate Assessment Report
Haze Over Bangladesh|
January 20, 2013 | NASA's Earth Observatory
“On January 10, NASA’s Aqua satellite captured this image of haze hugging the Himalayas and spilling out into the Ganges delta and Bengal Sea.The haze likely resulted from a combination of urban and industrial pollution, agricultural fires, and a regional meteorological phenomenon known as a temperature inversion.” Quoted from the NASA image release.
