NASA`s CPEX Tackles a Weather Fundamental
(World News Science)

A NASA-funded field campaign getting underway in Florida on May 25 has a real shot at improving meteorologists` ability to answer some of the most fundamental questions about weather: Where will it rain? When? How much? Called the Convective Processes Experiment (CPEX), the campaign is using NASA`s DC-8 airborne laboratory outfitted with five complementary research instruments designed and developed at NASA. The plane also will carry small sensors called dropsondes that are dropped from the plane and make measurements as they fall. Working together, the instruments will collect detailed data on wind, temperature and humidity in the air below the plane during the birth, growth and decay of...
