| 摘 要： | The Indian summer monsoon rainfall （ISMR） plays an important role in the climate system of South Asia. Recently, studies about ISMR variations have been going into more depth. In this present paper, we mainly use the Scargle periodogram and wavelet transform methods to study the periodicity of ISMR changes between 1871 and 2004 and review the possible influence of solar activity on the rainfall. Analysis results show complicated ISMR variations have periodicities with remarkable time-variable characteristics. Investigating a possible connection between the rainfall and solar variations, we believe that solar activity affects the ISMR variations to some extent.

| Abstract: | The Indian summer monsoon rainfall (ISMR) plays an important role in the climate system of South Asia. Recently, studies about
ISMR variations have been going into more depth. In this present paper, we mainly use the Scargle periodogram and wavelet
transform methods to study the periodicity of ISMR changes between 1871 and 2004 and review the possible influence of solar
activity on the rainfall. Analysis results show complicated ISMR variations have periodicities with remarkable time-variable
characteristics. Investigating a possible connection between the rainfall and solar variations, we believe that solar activity
affects the ISMR variations to some extent.
