Abstract :Using ground-based neutron monitor data of Deep River, the high amplitude anisotropic wave train events insert ignore into journalissuearticles values(HAE); in cosmic ray intensity have been investigated during the period 1991--1994. It has been observed that the phase of diurnal anisotropy for majority of HAE cases remains in the same co-rotational direction, whereas for some HAE cases the phase of diurnal anisotropy has shifted to later hours. For the majority of HAE cases the amplitude of semi-diurnal anisotropy remains statistically the same, whereas the phase of semi-diurnal anisotropy for all HAE cases has shifted to later hours. Furthermore, for tri-diurnal anisotropy the phase shifts towards later hours while amplitude remains statistically the same.Keywords : Cosmic ray, diurnal, semi diurnal, and anisotropy
