Description:
Flux ropes are frequently observed in the space plasmas, such as magnetosphere, magnetosheath, and solar wind etc., and play an important role in the reconnection process and mass and flux transportation. One usually used bipolar signature and strong core field to identify the flux ropes. We propose here one new method to identify flux ropes based on the correlations between the variables of the data from in-situ spacecraft observations and the target-function-to-be-correlated (TFC) from the ideal flux rope model. Through comparing the correlation coefficients of different variables at different time and scales, and performing weighted average technique, this method can derive the scales and locations of the flux ropes. We discuss the limitation of our method and also compare it with other methods.
