“…Two important conditions for excitating geophysical events are high speed solar wind carrying enough energy and planetary magnetic field. The above analysis shows the important influence of the solar magnetic direction variation on the tropospheric air temperature anomaly sign, suggesting that the significant 22-year periodic variability of the air temperature in the northern hemisphere is excitated by the solar activity [29] , and is response to the intensity and direction variations of the solar magnetic field. The temperature curve in Fig.1 is not so regular like the MI curve, because except for solar activity, the air temperature is also impacted by other factors, whose influence is far less than that of solar activity.…”

Based on 11‐year's period data of the sunspot and the periodic variation of the magnetic field of the sunspot, the time series of the magnetic index of the sunspot magnetic field (MI) is established. The analysis indicates that the average period of the solar magnetic activity is about 22.2 years, but it is not a constant. In most cases, when the period is short, the magnetic index is large, corresponding to strong solar activity; when the period is long the magnetic index is small, corresponding to weak solar activity. The time series of magnetic index of the sunspot magnetic field has also a period of 80~90 years. This study shows that during the period of MI curve rising from its minimum to maximum, the solar magnetic field is southward, and the planetary magnetic lines and the Earth magnetic lines meet together. The magnetic layer is an open layer, with the solar wind entering into the Earth magnetic layer from the sunny side taking plenty of plasma, increasing the input kinetic, heat and electromagnetic energy greatly, which corresponds to the temperature increasing period in the troposphere of the Northern Hemisphere. On the other hand, during the period of MI curve descending from the maximum to minimum, the solar magnetic field is northward, same as the top of the magnetic layer direction, and the planetary magnetic lines and the Earth magnetic lines do not meet. The magnetic layer is a close layer; only a few electriferous particles can enter the Earth magnetic layer through magnetic lines, corresponding to the temperature decreasing period in the troposphere of the Northern Hemisphere.

“…Solar variation plays an important role in affecting changes in weather, space weather and climate on Earth (Camp and Tung 2007). Some researches (Qu et al 2004;Cong et al 1995) indicated that the sun activities influence the condition of climate and atmosphere by way of radiation changes and inspiring the magnetic field change in the earth, thus affecting the climate in the earth. The two ways are closely related to the magnetic field changes in the sunspot activities.…”

The Wei River Basin, a typical arid and semi-arid region, is frequently attacked by droughts, which heavily limits its sustainable development of society and economy. Therefore, the main motivation of this study is to investigate the drought evolution characteristics and risk evaluation in the basin, which is crucial for drought warning, water resources management as well as agricultural development. The modified Mann-Kendall test trend method was used to capture the trend of the severity and duration of historical drought events, and the persistence of droughts was analyzed based on the Rescaled Range (R/S) analysis. Additionally, the Morlet wavelet analysis was utilized to calculate the period of dry and wet condition, and copulas were applied to calculate the joint return period of two typical scenarios. The main results are as follows: (1) the whole basin has an obviously dry trend, especially in autumn and winter; furthermore, the months with a wet trend are primarily concentrated in July and August; (2) the persistence of droughts is strong, indicating that droughts in the near future may be persistent; (3) the average "or" and "and" joint return periods under scenario (1) where drought duration is 6 months and drought severity is 4 are approximately 15.6 and 28.9 years, respectively, while those under scenario (2) where drought duration is 8 months and drought severity is 6 are approximately 34.9 and 53.1 years, respectively. In general, the drought risk of the northwestern basin is larger than that of the southeastern basin.

Abstract. The relationship between the periodic movement of the planetary system and its influence on solar activity is currently a serious topic in research. The kinematic index of the planet juncture index has been developed to find the track and variation of the Sun around the centroid of the solar system and the periodicity of solar activity. In the present study, the kinematic index of the planetary system's heliocentric longitude, developed based on the orbital elements of planets in the solar system, and it is used to investigate the periodic movement of the planetary system. The kinematic index of the planetary system's heliocentric longitude and that of the planet juncture index are simulated and analyzed. The numerical simulation of the two kinematic indexes shows orderly orbits and disorderly orbits of 49.9 and 129.6 years, respectively. Two orderly orbits or two disorderly orbits show a period change rule of 179.5 years. The contrast analysis between the periodic movement of the planetary system and the periodicity of solar activity shows that the two phenomena exhibit a period change rule of 179.5 years. Moreover, orderly orbits correspond to high periods of solar activity and disorderly orbits correspond to low periods of solar activity. Therefore, the relative movement of the planetary system affects solar activity to some extent. The relationship provides a basis for discussing the movement of the planetary system and solar activity.
