This year, there will be about 15 storms from

Experts from the Institute of Geophysics (Vietnam Academy of Science and Technology), said this year there will be about 15 storms from occurring and less likely to occur from strong storms.

'2007 is the year in the cycle of weak magnetic storms. The intensity of storms from this year is very small, less likely to affect health as well as other scientific and technological activities of people ' - Assoc. Prof. Dr. Ha Duyen Chau - Deputy Director of the Institute of Geophysics affirmed.

Also according to the warning of PGS-TS Ha Duyen Chau, the years 2010 and 2011 will be strong years of magnetic storms with strong intensity and can affect health as well as other scientific and technological activities. of human. According to scientists, the five strong active storms are also the number of cardiovascular and neuro-related hospital admissions increased by more than 30%.

According to statistics from the Institute of Geophysics on local stations from Vietnam, 1989 was the year of the most storms with 44 matches. In 2000 there were 40 storms from, in 2004 there were 27, in 2006 there were about 15 matches. Storm from the least appeared in 1986 with 17 matches.

The years from 2000-2003 are the most intense magnetic storm years with the strongest intensity, up to more than 650 nT. The strongest and most influential storm from Vietnam in recent years is a storm from March 31, 2001, with a intensity of over 630 nT.
