Dozens of strong storms and storms can pour into Vietnam

Vietnam may be affected by 40 to 45 storms from the strongest intensity this year.

Associate Professor, Dr. Ha Duyen Chau, former Director of the Institute of Geophysics, said that according to the 11-year cycle, at the end of 2012 and the beginning of 2013 was the time of the storm surge. However, last year, magnetic storms occurred at a weak level, with about 30 matches, so according to Dr. Chau, it is likely that this year will be the time of explosive storms.

"As predicted, the number of storms from 2013 can be up to 40 to 45 matches at the strongest level G4, G5 ie about 400-500nT (ano Tesla-unit measuring the intensity of magnetic storms)" , Dr. Chau said.

Mr. Chau warns, magnetic storms with intensity of 200nT or more will affect human health. In the bones, heart, brain, there are magnetic cells, so people with a history of cardiovascular and neurological diseases, osteoarthritis diseases are very sensitive to magnetic storms, mildly feel tired, stressed, hurt themselves Osteoarthritis

In the industry, when a storm occurs, a large induced current will appear in the transformer of the 500kV transmission system. This current damages the automatic relay of the substation, affecting the operation of the substation and power supply.

Magnetic storms occur when charged particles emanating from the solar wind affect the entire earth. They can paralyze the operation of artificial satellites and even attack power networks on the ground. Scientists have calculated that magnetic storms reach a maximum of 11 years.
