Space weather moves from observation toward prediction

WASHINGTON - Two hurricane seasons are currently in full swing. The more familiar hurricanes, composed of high winds and heavy rains, primarily affect the east coast of North America for several months each year, and they are often dramatic and devastating. The other hurricanes are, for the most part, not visible to the naked eye; their season lasts for years; and they can in their own way be just as devastating. They are part of the phenomenon known as space weather.

Space weather is the term used to describe conditions caused by the flow of magnetic material from the Sun to the Earth. Its greatest impact occurs in the years just before and after the Sun's most active period in its 11-year cycle, which is to say, now. The analogy to a hurricane is apt, says Prof. George L. Siscoe of Boston University's Center for Space Physics and co-editor of "Space Weather," published by the American Geophysical Union. These "hurricanes" from space can devastate orbiting satellites upon which we all depend and have even wiped out power grids on Earth, he noted. Like atmospheric hurricanes, they can damage human health and take lives.

The publication this month of "Space Weather," the first peer-reviewed scientific book on the subject, marks the fifth anniversary of the establishment of the U.S. National Space Weather Program. During that time the science has moved from simply observing solar storms to the beginnings of prediction, allowing managers of sensitive equipment on Earth and in space to take steps before damage occurs.

In March 2000, more than 160 scientists and students from a dozen countries gathered in Clearwater, Florida, to assess progress in the science of space weather. Their reports form the basis of "Space Weather." Edited by Paul Song of the University of Massachusetts in Lowell, Howard J. Singer of the National Oceanic and Atmospheric Administration in Boulder, Colorado, and Siscoe, it draws together multidisciplinary research over five years, enabling scientists in any relevant area of research to learn what colleagues have discovered in other areas. The first nine chapters are nontechnical, outlining the nature and history of space weather observations, and are accessible to lay readers.
