Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by the China Meteorological Administration. This standard by the national meteorological satellites and space weather Standardization Technical Committee on Space Weather Monitoring and Warning Technical Committee (SAC/TC347/SC3) centralized. This standard was drafted. National Satellite Meteorological Center (National Space Weather Monitoring and Warning Center). The main drafters of this standard. your music Ming, Chen Bo, Zhaohai Juan. Geomagnetic storm intensity level

1 Scope

This standard specifies the level of intensity of geomagnetic storms. This standard applies to the monitoring and forecasting of storms.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Earth's magnetic field vector geomagneticfieldvector Earth's magnetic field magnetic induction vector. 2.2 Geomagnetic horizontal component geomagnetichorizontalcomponent Magnetic field vector in the horizontal plane of the projector. 2.3 Geomagnetic storm geomagneticstorm magnetic storm Worldwide Mainland continued intense magnetic disturbances. Note. The duration of the disturbance between hours to days, the horizontal component of the geomagnetic perturbation amplitude is usually in the tens of Nath (represented by nT) to hundreds of Nat Inter, in extreme cases more than a thousand Nat. 2.4 Geomagnetic storm main phase mainphaseofgeomagneticstorm Low-latitude geomagnetic horizontal component of geomagnetic storms began to decline during the process to minimize the value from. 2.5 Geomagnetic equator geomagneticequator On the surface of the earth poles apart 90 ° in the great circle of dots. 2.6 International magnetically quiet day internationalquietday Worldwide Mainland magnetic field in each month of the most peaceful days. 2.7 Dst index Dstindex Description geomagnetic storm activity level index. NOTE. The Greenwich hour intervals, the usual level of geomagnetic four stations on the international component to eliminate international magnetically quiet day and long-term changes, and imputed to the When the geomagnetic equator after mean to Nat (nT) as a unit. See Appendix common geomagnetic station location information of four international A. 2.8 K index Kindex Time interval for a single station of geomagnetic activity index 3h. Note. according to GMT, starting from zero, every three hours as a period of a day, a total of eight data. Each recording geomagnetic three component geomagnetic station During and after each time period in order to eliminate the internal rules of the diurnal variation of the maximum amplitude component as the basis, according to the strength of geomagnetic activity is divided into 0 to 9, a total of 10 levels. ...
