A BRIEF REVIEW, RECENT DEVELOPMENT IN INTERPLANETARY PHYSICS AND MAGNETOSPPHERIC PHYSICS

The interplanetary physics has been blooming in the important problems such as thesolar wind acceleration, the interaction between high and low speed streams, the propa-gation of flare relatd shocks, etc. since last decade. Especially worth to note among themis the identification of magnetic cloud in the interplanetary(IP) space. The developmentof these problems shows that there exist complex structures of different scales. One can
