"For more than 127 years POWER magazine has been considered the definitive information source for the power generation market. We covered the earliest advances of steam power plants in the 1800s and addressed energy supply issues during World Wars I and II. We were the first to report on the birth of nuclear power, and today we report on modern advanced power technologies, including wind, solar, tidal, and ultrasupercritical generation. Our coverage of the worldwide power generation industry, which includes all fuel types and generation technologies, has never been more critical as the world grapples with so many supply options and regulatory hurdles."

New Unpublished Manuscript - Hurricane Isabel Intensity

Recent dropsonde observations in hurricane Isabel provided unprecedented high quality data on eyewall: air temperature, relative humidity and sea surface temperature. This January 2007 manuscript shows that eyewall temperature and humidity can be used to calculate minimum eyewall pressure and maximum wind speed.
