North American Countries Reach Consensus on El Nino Definition

WASHINGTON , NOAA, the National Oceanic Atmospheric
Administration, announced today that NOAA's National Weather Service, the
Meteorological Service of Canada and the National Meteorological Service of

is bent by a prism, these radio waves are bent by electrically charged gas
trapped in the Earth 's magnetic field.
According to the lightning theory, radio waves clear the safe zone by
interacting with the radiation belt particles, removing a little of their
energy and changing their direction .
According to the team, there would not be a correlation if the radio waves
came from space instead of Earth. Bodo Reinisch, University of
