Description
It has been found that most of the near earth thunderstorms electric field strength at YBJ (4300 m a.s.l., Tibet, China) is within the range of 1000V/cm from ARGO-YBJ data. In this work, Monte Carlo simulations were performed by CORSIKA to study the intensity change of the ground cosmic rays in near earth thunderstorms electric fields. We found that the number of electrons in secondary particles at YBJ was changed with the strength and polarity of the electric field. In the negative field, the number increases with the strength of the fields. Nevertheless, it increases, or does not change obliviously or even declines with different energies of primary particles in the different positive fields. Our results are consistent with the observations obtained from ARGO-YBJ during thunderstorms. What is more, these preliminary results provide important information in understanding the acceleration mechanism of secondary charged particles caused by electric field.
