A method of data and velocity jumps determination based on the linear and parabolic trends in the integrated time series is highly sensitive to any impulse behavior of the observed variations due to various geophysical processes like earthquakes, tornadoes, hurricanes, geomagnetic jerks or to some systematic data deviations. The application to searching small data jumps hidden inside the level of random noise and high frequency oscillations of the polar motion is presented.
