| 中文摘要 | 分析了1996—2002年南北半球的太阳黑子相对数和南北半球太阳X射线耀斑级别(简称Imp)≥M1.0的太阳X射线耀斑的特征和不对称性.分析结果表明,南北半球的太阳耀斑活动的程度交替上升,在2001年7月以前北半球的太阳耀斑活动强于南半球, 2001年7月开始耀斑活动逐渐以南半球为主.本文还逐月分析了1996—2001年南北半球的耀斑指数. 2000年7月为第23周太阳指数最大的一个月、与第23周太阳黑子相对数最大月均值吻合. |
| 英文摘要 | Solar flares are believed to result from the sudden release of energy stored in magnet field． In this paper the X—ray solar flares with importance greater than and equal to M 1．0 occurred from 1996 to 2002 on the South and North of the solar disk are investigated． The results show that the intensity of the solar flare activities occurred in the Northern and Southern hemisphere is diferent． As a whole，the solar flare activities in north hemisphere are m ore intense than that in the south hem isphere during the interval form 1996 to July 2001，while the situation is contrary from August 2001 to 2002．The period of the most intense solar activities for Solar Cycles 23 is July 2000．The solar flare activities in November 1999，M arch 2000，M arch and April 2001，September to December 2001 and July to August 2002 are also very intensive． The solar flare index for the interval from 1996— 2001 is also investigated．The result shows that the value of solar flare index of the north hem isphere in July 2000 has the biggest va lue and very outstanding which means that the solar activities in July 2000 are the most intensive for Solar Cycle 23． This result is consistent with that the m onthly sunspot numbers having the biggest value in July 2000 for Solar Cycle 23．Because the biggest value of the smoothed m ontllly mean sunspot number in Solar Cycle 23 is 120．4 in April 2000，SO the m onthly m ean sunspot numbers can depict the solar activity better than smoothed monthly mean sunspot numbers．Now we can’t judge which hemisphere’S solar flare activities are more intensive，we will get the answer till the end of the Solar Cycle 23．If we want to really com pare the solar activities for Solar Cycle 23 between the two hemispheres，the whole areas of the sunspot，coronal mass ejections，and solar proton events and SO on must be com pared between two hemi spheres． |
