“Weakening of tropical Pacific atmospheric circulation due to anthropogenic forcing”

Gabriel A. Vecchi, Brian J. Soden, Andrew T. Wittenberg, Isaac M. Held, Ants Leetmaa, and Matthew J. Harrison (Nature 441, 73-76.) 

This paper explores changes in tropical Pacific Walker Circulation since the mid-19th century, using observations and a suite of global climate model experiments, and explores how the circulation should weaken over time.   ABSTRACT

“The role of carbon dioxide in climate forcing from 1979 to 2004: introduction of the Annual Greenhouse Gas Index”

David J. Hofmann, James H. Butler, Edward J. Dlugokencky, James W. Elkins, Kenneth Masarie, Stephen A. Montzka and Pieter Tans (Tellus, 58B, 614-619.)

This paper provides results of an analysis of all long-lived atmospheric greenhouse gasses, looks at how the various gasses are increasing, and combines the gasses into a single Atmospheric Greenhouse Gas Index.   ABSTRACT

“Large upper tropospheric ozone enhancements above midlatitude North America during summer: In situ evidence from the IONS and MOZAIC ozone measurement network”

Owen R. Cooper, Andreas Stohl, Michael Trainer, Anne M. Thompson, Jacquelyn C. Witte, Samuel J. Oltmans, Gary Morris, Kenneth E. Pickering, James H. Crawford, Gao Chen, Ronald C. Cohen, Timothy H. Bertram, Paul J. Wooldridge, Anne E. Perring, William H. Brune, John Merrill, Jennie L. Moody, David Tarasick, Philippe Nédélec, Gerry Forbes, Michael J. Newchurch, Frank J. Schmidlin, Bryan J. Johnson Solene Turquety, Steven L. Baughcum, Xinrong Ren, Fred. C. Fehsenfeld, James F. Meagher, Nicole Spichtinger, Clyde C. Brown, Stuart A. McKeen, I. Stuart McDermid, and Thierry Leblanc (Journal Of Geophysical Research, 111, D24S05, doi:10.1029/2006JD007306)

This paper quantifies the occurrence of the upper tropospheric ozone enhancement and provides a detailed analysis of its origin.   ABSTRACT

ECOSYSTEMS

“Submarine venting of liquid carbon dioxide on a Mariana Arc volcano”

John Lupton, David Butterfield, Marvin Lilley, Leigh Evans, Ko-ichi Nakamura, William Chadwick Jr., Joseph Resing, Robert Embley, Eric Olson, Giora Proskurowski, Edward Baker, Cornel de Ronde, Kevin Roe, Ronald Greene, Geoff Lebon, Conrad Young (Geochemistry, Geophysics, Geosystems, 7, Q08007, doi:10.1029/2005GC001152)

This paper reports on the discovery of unusual natural venting of liquid carbon dioxide from Northwest Eifuku, a small submarine volcano in the Northern Marianas Arc in the western Pacific, only the second locality where liquid CO2 has been found to occur naturally in the ocean.   ABSTRACT

WEATHER & WATER

“Flooding on California’s Russian River: Role of atmospheric rivers”

F. Martin Ralph, Paul J. Neiman, Gary A. Wick, Seth I. Gutman, Michael D. Dettinger, Daniel R. Cayan, Allen B. White (Geophysical Research Letters, 33: L13801, doi: 10.1029/2006GL026689.)

This paper takes recent results and documents the importance of atmospheric rivers in the global water cycle, and documents their importance in creating precipitation and flooding on the U.S. West Coast.   ABSTRACT

“The Joint Polarization Experiment: Polarimetric Rainfall Measurements and Hydrometeor Classification”

Alexander V. Ryzhkov, Terry J. Schuur, Donald W. Burgess, Pamela L. Heinselman, Scott E. Giangrande, Dusan S. Zrnic (Bulletin of the American Meteorological Society, Jun 2005, 86: 809-824.)

This paper presents an overview of the joint polarization experiment and describes principle findings impacting operational oceanography. It demonstrates on tens of rainfall events the superior quality of estimates, and improvement by a factor of two in errors and elimination of bias.   ABSTRACT

SPECIAL RECOGNITION

“Dynamic Data Assimilation: A Least Squares Approach”

John M. Lewis, S. Lakshmivarahan, Sudarshan Dhall (Cambridge University Press, 2006)

This textbook provides a very complete treatment of the subject of data assimilation, introducing concepts with simplified examples, and provides an abundance of exercises and associated history of the development of ideas.   ABSTRACT
