2017 Accumulated Cyclone Energy

by Dr. Ryan N. Maue, May 01, 1017


Tropical cyclone accumulated cyclone energy (ACE) has exhibited strikingly large global interannual variability during the past 40-years. In the pentad since 2006, Northern Hemisphere and global tropical cyclone ACE has decreased dramatically to the lowest levels since the late 1970s. Additionally, the frequency of tropical cyclones has reached a historical low. Here evidence is presented demonstrating that considerable variability in tropical cyclone ACE is associated with the evolution of the character of observed large-scale climate mechanisms including the El Nino Southern Oscillation and Pacific Decadal Oscillation. In contrast to record quiet North Pacific tropical cyclone activity in 2010, the North Atlantic basin remained very active by contributing almost one-third of the overall calendar year global ACE.

Can the U.S. Become the Saudi Arabia of Natural Gas?

by David Middleton, April 28, 2017


The Department of Energy gave a Texas-based energy company permission Tuesday to export liquefied natural gas (LNG) to countries with which the U.S. does not have free trade agreements.

While low U.S. natural gas prices are currently a drag on production and reserve growth, they also provide an advantage to domestic gas producers.  U.S. natural gas is extremely competitive in the global market.
