Abstract : A variety of cool-jets are observed in the lower part of the solar atmosphere carrying energy and mass to the overlying corona. Recent observations also demonstrate their impulsive origin in the localized solar atmosphere. We present the numerical simulations of a variety of cool jets that have impulsive origin (e.g., trigger by pressure pulse, velocity enhancement, Alfven pulses). We suggest that such physical mechanisms are important for the formation of the cool and confined jets in the solar atmosphere. These jets are predominantly associated with the formation of magnetoacoustic shocks, and mimic the observations. They carry substantial mass and energy in the overlying TR and inner corona, therefore, can be important candidates for the localized heating and mass transport. It also manifest that non-ideal plasma environment may significantly affect the kinematics and energetics of such jets despite of their diverse physical origin.
