Summary:
The main objective of our `solar-interplanetary' studies is to make a detailed study of solar events on the surface of the Sun, to understand their evolution in the inner heliosphere, and, to investigate their effects at the near-Earth environment. The most dramatic events on the Sun, in so far as intense magnetic storms at the Earth are concerned, are solar flares and coronal mass ejections (CMEs). A flare-CME event may cause a variety of radio burst activities and radio measurements of a CME in the near-Sun region can provide a valuable probe to infer the magnetic field configuration of the CME-generating solar region. In the space between the solar surface and the Earth, the interplanetary scintillation (IPS)technique can provide important information on the size, speed, and density turbulence associated with propagating disturbances caused by CMEs. In this proposal, we plan to study specific cases of CME formation and initiation and their propagation in the interplanetary space. We shall address the following issues:
