Geophysical Research Letters is a semi-monthly peer reviewed scientific journal published by the American Geophysical Union that was established in 1974. The editor-in-chief is Eric Calais (Purdue University). The stated purpose of Geophysical Research Letters is rapid publication of conscise research reports that may significantly influence one or more American Geophysical Union disciplines. These particular geoscience disciplines are atmospheric sciences, solid earth, space sciences, ocean sciences, hydrology, land surface processes, and the cryosphere. GRL also publishes twelve invited reviews that cover advances achieved during the past two or three years. The target readership is the earth science community, the broader scientific community, and the general public. This journal is indexed in the following databases: According to the Journal Citation Reports, the journal has a 2010 impact factor of 3.505, ranking it 12th out of 165 journals in the category "Geosciences, Multidisciplinary". Geophysical Research Letters was also the 5th most cited publication on climate change between 1999 and 2009.
Tornadoes occurring earlier in 'Tornado Alley'
Peak tornado activity in the central and southern Great Plains of the United States is occurring up to two weeks earlier than it did half a century ago, according to a new study whose findings could help states in "Tornado ...
'Shocking' underground water loss in US drought
A major drought across the western United States has sapped underground water resources, posing a greater threat to the water supply than previously understood, scientists said Thursday.
Global warming 'pause' since 1998 reflects natural fluctuation, study concludes
Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by McGill ...
Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. ...
Two dynamos drive Jupiter's magnetic field
(Phys.org) —Superlatives are the trademark of the planet Jupiter. The magnetic field at the top edge of the cloud surrounding the largest member of the solar system is around ten times stronger than Earth's, and is by far ...
Study faults a 'runaway' mechanism in intermediate-depth earthquakes
Nearly 25 percent of earthquakes occur more than 50 kilometers below the Earth's surface, when one tectonic plate slides below another, in a region called the lithosphere. Scientists have thought that these rumblings from ...
Changing Antarctic winds create new sea level threat
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
Trade winds ventilate the tropical oceans
Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and ...
Mercury's magnetic field tells scientists how its interior is different from Earth's
Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.
Blackpool earth tremors during 'fracking' induced on ancient fault
New research has demonstrated that the 2011 Blackpool earth tremors during 'fracking' were induced on an ancient pre-existing fault.
