【摘要】：太陽(yáng)是唯一一顆給地球提供能量的恒星,它驅(qū)動(dòng)著地球上幾乎所有已知的自然和生態(tài)系統(tǒng),維持著地球上所有生命適合的生存環(huán)境。因此,對(duì)太陽(yáng)活動(dòng)及其變化規(guī)律的研究是非常有意義和必須的。本文主要研究了太陽(yáng)磁場(chǎng)的周期以及其在太陽(yáng)周時(shí)間尺度上與太陽(yáng)總輻照的關(guān)系,其主要結(jié)果如下:1、在威爾遜山天文臺(tái)(Mount Wilson Observatory,MWO),從1976年1月19日起就開(kāi)始測(cè)量每天的太陽(yáng)全日面綜合磁圖,并且利用每天觀測(cè)的磁圖計(jì)算了每天的太陽(yáng)磁場(chǎng)譜斑強(qiáng)度指數(shù)(Magnetic Plage Strength Index,MPSI)和威爾遜山黑子指數(shù)(Mount Wilson Sunspot Index,MWSI)。MPSI表征的是太陽(yáng)全日面的弱磁場(chǎng)活動(dòng),而MWSI表征的是太陽(yáng)全日面的強(qiáng)磁場(chǎng)活動(dòng)。利用MPSI和MWSI這兩組時(shí)間序列,通過(guò)自相關(guān)的分析方法調(diào)查了太陽(yáng)全日面磁場(chǎng)活動(dòng)的周期。MPSI(太陽(yáng)全日面弱磁場(chǎng)活動(dòng))和MWSI(太陽(yáng)全日面強(qiáng)磁場(chǎng)活動(dòng))僅僅只有兩個(gè)周期:一個(gè)是太陽(yáng)活動(dòng)周,另一個(gè)太陽(yáng)自轉(zhuǎn)周,并且這兩個(gè)指數(shù)都沒(méi)有年變化的周期信號(hào)。MPSI的太陽(yáng)活動(dòng)周周期是10.83年,而MWSI的周期是9.77年,MPSI的周期明顯長(zhǎng)于MWSI的周期。MPSI的自轉(zhuǎn)周期是26.8±0.63天,而MWSI的自轉(zhuǎn)周期是27.4±2.4天。MPSI的自轉(zhuǎn)周期圍繞27.0天并且漲落非常小,而MWSI的自轉(zhuǎn)周期的振幅有一個(gè)較大的波動(dòng)。MWSI在太陽(yáng)活動(dòng)極小期附近的自轉(zhuǎn)周期比在太陽(yáng)活動(dòng)極大期的自轉(zhuǎn)周期長(zhǎng)。MPSI和MWSI的交叉相關(guān)分析表明,太陽(yáng)弱磁場(chǎng)(MPSI)的成分部分是來(lái)自于相對(duì)早期的太陽(yáng)強(qiáng)磁場(chǎng)活動(dòng)(MWSI)。2、利用斯坦福大學(xué)威爾科克斯太陽(yáng)天文臺(tái)(Wilcox Solar Observatory of the Stanford University,WSO)觀測(cè)的1975年到2014年的太陽(yáng)平均磁場(chǎng)數(shù)據(jù),應(yīng)用新的總體經(jīng)驗(yàn)?zāi)Ｊ椒纸?Ensemble Empirical Mode Decomposition,EEMD)來(lái)抽取太陽(yáng)平均磁場(chǎng)的本征模函數(shù)(Intrinsic Mode Function,IMF),然后再分析這些本征模函數(shù)的周期,以及本征模函數(shù)(太陽(yáng)平均磁場(chǎng))與一些太陽(yáng)活動(dòng)代理物之間的關(guān)系。太陽(yáng)平均磁場(chǎng)有兩個(gè)特殊的自轉(zhuǎn)周期26.6和28.5天,這兩個(gè)特殊的周期應(yīng)該來(lái)自太陽(yáng)平均磁場(chǎng)的不同磁流成分。26.6天的自轉(zhuǎn)周期來(lái)自于太陽(yáng)平均磁場(chǎng)的弱磁流成分,而28.5天的自轉(zhuǎn)周期來(lái)自于太陽(yáng)平均磁場(chǎng)的強(qiáng)磁流成分。而且,黃道面附近的行星際磁場(chǎng)結(jié)構(gòu)的兩個(gè)自轉(zhuǎn)周期本質(zhì)上也是分別與太陽(yáng)平均磁場(chǎng)的弱磁流和強(qiáng)磁流成分相關(guān)。太陽(yáng)平均磁場(chǎng)的弱磁流成分在過(guò)去的四十年自轉(zhuǎn)周期是不變的,原因是來(lái)自于太陽(yáng)表面弱磁場(chǎng)活動(dòng)的弱磁流成分不受緯度漂移的影響。既不是太陽(yáng)內(nèi)部的旋轉(zhuǎn),也不是太陽(yáng)表面的磁場(chǎng)活動(dòng)(包括極區(qū)磁場(chǎng))引起太陽(yáng)平均磁場(chǎng)在年時(shí)間尺度上的變化。太陽(yáng)平均磁場(chǎng)在一個(gè)太陽(yáng)周時(shí)間尺度上的變化更多的是與太陽(yáng)表面的弱磁場(chǎng)活動(dòng)相關(guān)。3、PMOD TSI,ACRIM TSI和RMIB TSI是三組比較典型的TSI合成數(shù)據(jù)。MPSI和MWSI分別表征太陽(yáng)全日面的弱和強(qiáng)的磁場(chǎng)活動(dòng)。三組TSI與MWSI的交叉相關(guān)分析表明TSI與MWSI在太陽(yáng)活動(dòng)周上是弱相關(guān)的,并且二者相位不同。小波調(diào)諧和部分小波調(diào)諧也指出TSI隨太陽(yáng)周的長(zhǎng)周期變化是與MWSI代理的太陽(yáng)強(qiáng)磁活動(dòng)無(wú)關(guān)的。然而,三組TSI與MPSI的交叉相關(guān)分析表明TSI與MPSI在太陽(yáng)活周時(shí)間尺度上中度相關(guān)并且相位相同,而且統(tǒng)計(jì)意義檢驗(yàn)指出三組合成的TSI與MPSI的相關(guān)系數(shù)有統(tǒng)計(jì)意義的高于三組合成的TSI與MWSI的相關(guān)系數(shù)。并且,小波交叉和小波調(diào)諧也驗(yàn)證了TSI與MPSI在太陽(yáng)活動(dòng)周時(shí)間尺度上高度相關(guān)并且相位一致。因此,交叉相關(guān)分析、小波交叉和小波調(diào)諧都指出MPSI表征的太陽(yáng)全日面的弱磁場(chǎng)活動(dòng),控制著TSI隨太陽(yáng)周的長(zhǎng)周期變化。
[Abstract]:The sun is the only star that provides energy to the earth. It drives almost all known natural and ecological systems on the earth and maintains all the life's suitable living environment on the earth. Therefore, it is very meaningful and necessary to study the solar activity and its changing laws. This paper mainly studies the cycle of the solar magnetic field and its field. The main results are as follows: 1, at Mount Wilson Observatory (MWO), the daily total solar comprehensive magnetograph of the sun has been measured from January 19, 1976, and the daily solar magnetic field spectrum intensity index (Magnetic) is calculated using the daily observed magnetograph (Magnetic The Plage Strength Index, MPSI) and the Wilson Yama Kuroko exponent (Mount Wilson Sunspot Index, MWSI).MPSI represent the weak magnetic field activity of the solar whole day, while MWSI represents the strong magnetic field activity of the sun, using the two time series of MPSI and the self phase correlation analysis to investigate the activity of the solar whole surface magnetic field. Periodic.MPSI (solar whole day weak magnetic field activity) and MWSI (solar full solar magnetic field activity) only have only two cycles: one is solar activity week, another solar cycle, and the two exponents have no annual variation of periodic signal.MPSI, the cycle of solar activity is 10.83 years, while the cycle of MWSI is 9.77 years, and the cycle of MPSI is obvious The rotation period of the cycle.MPSI longer than MWSI is 26.8 + 0.63 days, while the rotation period of MWSI is 27.4 + 2.4 days, and the rotation period of.MPSI is around 27 days and the fluctuation is very small, while the amplitude of MWSI's rotation period has a larger fluctuation.MWSI in the rotation period of the solar activity minimum. The cross correlation analysis between MPSI and MWSI shows that the component part of the solar weak magnetic field (MPSI) is derived from the relative early solar magnetic field activity (MWSI).2, and the data of the solar average magnetic field from 1975 to 2014 of the Willcocks Solar Observatory of the Stanford University (Wilcox Solar Observatory of the Stanford University) should be observed. Using the new total empirical mode decomposition (Ensemble Empirical Mode Decomposition, EEMD) to extract the eigenmode function of the average solar magnetic field (Intrinsic Mode Function, IMF), and then analyze the period of these eigenmode functions and the relation between the eigenmode function (the sun mean magnetic field) and some solar active agents. The magnetic field has two special rotation cycles of 26.6 and 28.5 days. The two special periods should come from the different magnetic flux components of the average solar magnetic field.26.6 days from the weak magnetic flux of the average solar magnetic field, while the 28.5 day rotation period comes from the strong magnetic flux in the average solar magnetic field. Moreover, the planets near the ecliptic surface. The two rotation period of the magnetic field structure is essentially related to the weak magnetic current and the strong magnetic flux component of the average solar magnetic field. The weak magnetic flux of the average solar magnetic field is unchanged in the past forty years. The reason is that the weak magnetic flux from the weak magnetic field of the solar surface is not influenced by the latitude drift. The rotation in the sun is not the change in the annual scale of the sun's average magnetic field caused by the magnetic field activity on the surface of the sun (including the polar region magnetic field). The changes in the solar average magnetic field on a solar cycle time scale are more related to the weak magnetic field activity on the solar surface.3, PMOD TSI, ACRIM TSI and RMIB TSI are the three groups more typical. The TSI synthesis data.MPSI and MWSI represent the weak and strong magnetic field activities of the solar whole day respectively. The cross correlation analysis between the three groups of TSI and MWSI shows that TSI and MWSI are weakly related to the solar activity week, and the phase of the two is different. The cross correlation analysis between the three groups of TSI and MPSI shows that TSI and MPSI are moderately correlated and phase in the solar cycle time scale, and the statistical significance test indicates that the correlation coefficient of the three combination of TSI and MPSI is statistically significant higher than the correlation coefficient of TSI and MWSI formed by the three combination. The tuning of forks and wavelets also proves that TSI and MPSI are highly correlated and phase in the solar cycle time scale. Therefore, cross correlation analysis, wavelet cross and wavelet tuning all indicate the weak magnetic field activity of the solar whole day characterized by MPSI, which controls the long periodic changes of TSI with the sun.
