The complex magnetic structuring and highly dynamical nature of the solar atmosphere allow triggering of various cool spicule-like thin jets (T<105 K). These cool jets are basically collimated plasma ejecta that rise and fall quasi-periodically along the magnetic field lines in the Sun’s atmosphere. Several multiwavelength observations have been captured from space and ground based observatories revealing the evolution of these small scale cool jets and associated plasma processes (e.g., waves and oscillations, instabilities etc). Their physics can be understood extensively by performing numerical simulations. We numerically model such plasma jets in 2.5 D regime using the theory of Magnetohydrodynamics (MHD).
