Solar jets are ubiquitous transient collimated mass outflows in the solar atmosphere over a wide range of sizes embedded in the solar chromosphere to solar corona. Jets are frequently accompanied by solar flares and these flares provide the force to propagate the plasma material upward.
According to different theoretical models, magnetic reconnection is believed to trigger the activation of the jet phenomenon.

This talk will cover the different mechanisms to set off the jet initiation and observational aspects to validate the numerical experiments for the magnetic flux emergence models.
