Abstract

Chromospheric evaporation implies the mass flow from chromosphere to corona along the loop legs in the solar flares. From observations, radio emissions show the high-frequency cutoff and with a drift toward the low frequency, and the coronal lines display a strong blueshift on the Doppler diagram, and hard X-ray emissions tend to rise up the double footpoint sources along the loop legs and finally merge together around the top at the same position as the loop top source. In this paper, we briefly review the radio, EUV and X-ray evidences of the chromospheric evaporation from the documents in recent years.
