Radio observations and Space Weather Research

Magdalenic, Jasmina

Invited talk presented at The 4th AOSWA Workshop 2016, Jeju, South Korea on 2016-10-25

Abstract: Coronal mass ejections and associated shock waves are the most frequent drivers of disturbed geomagnetic conditions. Therefore, tracking of CMEs and the CME-driven shock waves from the low corona through the inner heliosphere became one of the most often addressed topics of the space weather research. Observations of solar radio emission associated with CME-driven shock waves are unique means for tracking the shocks, as the shock radio emission can be observed in a broad frequency range (from several hundred MHz down to a few kHz), which encompasses the whole solar atmosphere and the inner heliosphere. Moreover, in many instances, radio emission also brings unique information on the coronal parameters e.g. coronal magnetic field strength and coronal electron density. In this presentation I will discuss how the radio observations (from metric to kilometric wavelength range) can be used in the space weather forecasting. The focus will be on the so-called type II bursts, radio signatures of shock waves. I will also address some of the recent results of the radio triangulation studies (of type II, type III and type IV radio bursts) which bring completely new insight into the causal relationship of the CMEs and associated solar radio emission.
