From geysers and atmospheric jet streams on the Earth to spicules and coronal jets in the solar atmosphere, and astronomical jets from accretion disks, elongated eruptive events exist at a tremendous range of scales in the universe. Unlike their chromospheric counterparts, spicules, which have been widely suggested to be related to the global oscillation of the Sun, solar coronal jets have been mostly studied as localised events. In this talk, I will briefly summarise a series of our work on coronal jets from the aspects of their energy partition and rotational motion, before presenting our recent adventure of exploring the potential link between solar coronal jets and the solar cycle, based on a large dataset built from more than 1200 coronal jets automatically detected from the SDO observations in the past 10 years.
