Solar flares, the most energetic explosion in the solar system, are very spectacular, and they are accompanied by a variety of dynamic phenomena. They often affect environmental conditions of the Sun-Earth system and even the space surrounding the Earth, which cause intense geomagnetic storms at Earth. Therefore, understanding the current environmental conditions and forecasting the effects of disturbances as “space weather” are becoming more and more important. I analyze various phenomena associated with solar flares, a crucial source of disturbances, by using a number of observed data to gain an overall understanding of flares, which may contribute greatly to the development of space weather researches.
