摘要

We analyze data from 141 solar flares that were observed with the Yohkoh soft and hard X-ray telescopes to investigate the general characteristics of the soft X-ray high-temperature region above soft X-ray flare loops. We performed a careful analyses in order to obtain accurate temperature maps of the high-temperature regions, and found high-temperature regions of 15-35 million degrees above soft X-ray flare loops for 64 flares out of the 141 events. The region appears at the hard X-ray impulsive phase and its temperature reaches a maximum before the time of the soft X-ray peak. The volume emission measure of the region is 10~(47-48) cm~3 on the average, which is about ten times smaller than that of the 10 million degree flare loop below it. The high-temperature regions tend to move outwards at a speed of 10-20 km s~(-1), which is faster than the rising speed of the flare loops of 5-10 km s~(-1).
