摘要：
The average change in height of several constant pressure levels in the troposphere and lower stratosphere after a strong solar flare is described. The analysis covers the northern hemisphere north of 10°N and is based on a sample of 81 carefully selected flares from the period July 1957 through December 1959. The statistical significance of the results is tested by drawing a comparison with the results obtained when one applies exactly the same analysis to three samples of 81 random key-dates selected from the same period. Properties of the reaction pattern are (1) it is pronounced at high as well as low latitudes, (2) it consists of alternating cells of positive and negative height change, (3) it is established within six hours after the flare, and (4) the maximum response occurs near the tropopause. It appears more likely that the atmospheric reaction pattern can be attributed to very energetic solar particles rather than to enhanced ultraviolet radiation. © 1969 Birkhäuser Verlag.
