Erittäin mielenkiitoisia löydöksiä - mikähän El Niñon ja ja La Niñan
vaikutus täällä pohjoisessa oikeasti onkaan...?

"TRMM Satellite Proves El Nino Holds the Reins on Global Rains"
(Source: NASA)
NASA and Japan's Tropical Rainfall Measuring Mission (TRMM) satellite
has enabled scientists to look around the globe and determine where
the year-to-year changes in rainfall are greatest. Recently,
scientists found that the El Nino-Southern Oscillation is the main
driver of the change in rain patterns all around the world.
El Ninos occur when waters in the Central equatorial Pacific Ocean
warm. El Nino - Southern Oscillation (ENSO) marks a see-saw shift in
surface air pressure between Darwin, Australia and the South
PacificIsland of Tahiti. When the pressure is high at Darwin it is
low at Tahiti and vice versa. El Nino, and its sister event La Nina,
are the extreme phases of this southern oscillation.
