These DFs appears to be periodic. Our observations from GST/BBSO shows them to follow a perfect parabolic path. We have done a statistical measure on the parameters like duration, maximum velocity, deceleration. Analysis shows a positive correlation between the maximum velocity and the deceleration which is quite consistent with the numerical simulations done before. Our analysis shows that most of the jet like features in the active regions are caused by the upward propagating shocks in the chromosphere. |
