Listen: Roger O'neill, NBC And Simone discussed on Ground Zero with Clyde Lewis
"Aircraft, actually long slender clouds. Whether men are finding them especially fascinating because the theory is being developed that those long white lines may be changing our weather for the better details Roger O'Neill. The exhaust. From jet engines, usually seen as long thin trails of white clouds behind high flying jet airplanes. Maybe a big reason why there are thirty fewer days of sunshine a year in the mid west now than there were in nineteen hundred the daily range between high and low temperatures has also narrowed whether researchers studying cloud cover in ten midwestern states found a sharp increase in cloudiness with the increase in commercial jet travel, particularly in the main east-west jet corridor. There were even more clouds. A jet produces a controversial or cloud because it's exhaust consists primarily of water vapor in the absence of natural clouds, given the correct atmospheric condition jet aircraft in high frequency. Can almost completely cover the atmosphere visible atmosphere. With clouds Simone and says, unlike most changes in the atmosphere caused by man, this one is beneficial clouds help farmers in the midwest by blocking the sun temperature extremes can damage plants and speed up the evaporation of soil moisture in the winter city people benefit because clouds act as a blanket preventing warm air from escaping into the atmosphere. No one is trying to make clouds now using jet engines. But this study suggests that jet travel is inadvertently making our days, more, cloudy and someday whether researchers made able to use jets on purpose to change, our weather, Roger O'Neill, NBC news champagne, Illinois, someday, they will use the planes to manipulate our weather."
