Scientists need to work together to counter the solar storms

GENEVA, May 17 — RIA Novosti. Future growth of solar activity, which should peak in 2013, necessitating extensive international cooperation for the upcoming severe magnetic storms were not a disaster for humanity, the American meteorologists.

"The question is not whether there is or not (the threat), the question is when," — said Tuesday Kathryn Sullivan (Kathryn Sullivan), Deputy Head of the Agency's Atmospheric and Oceanic Research, USA (NOAA), speaking at the Congress of the World Meteorological Organization .

According to her, the world is increasingly dependent on technology infrastructure, it becomes more and more addicted to it to the extent that, as new technologies permeate our daily lives.

Satellite navigation and communications, energy and electricity infrastructure — these are some items that are vulnerable and can be damaged under the influence of solar storms, said Sullivan.

"The last peak of solar activity occurred in 2000, now we go from a minimum of solar activity, and in 2013 will be the highest level of solar storms," — she said.

Sullivan stressed that to prevent the negative impacts will require "global awareness."

"Without a coordinated international plan of action the extreme solar storm could become a global catastrophe, and lead to the most severe economic consequences," — she said.

"I want to urge all members of the WMO to contribute to the action of space weather and to act in a coherent and integrated way," — said the representative of the United States.

Disturbances in the Earth's magnetosphere — the magnetic storms — occur under the action of solar plasma of charged particles ejected Sun. Particles, "kick" of the magnetosphere, forcing it to vibrate, which can, in particular, to cause disruptions in radio.

Characterizing the strength of storms Kp index every three hours is calculated according to a network of ground stations. This scale has 10 levels, from 0 to 3 are the quiet magnetosphere, level 4 — perturbed, and the levels of 5 to 9 — magnetic storms five classes.

In 2000, there were 12 in the world top level of magnetic storms that led to the failure of power grids, radio blackouts and auroras observed up to the equator. The last such storm was on September 11, 2005.
