3. Solar Activity and Circulation Anomalies in Stratosphere

The Expression of Solar Activity HS= high(strong) solar activity LS= low(weak) solar activity According to the 107cm solar radio flux, we can get high and low solar active year as follows HS:1958,59,78,79, LS:1962,63,64,74, 80,81,88,89, 75,76,84,85, 90.91.2001 86.95,96

HS= high (strong) solar activity LS= low (weak) solar activity According to the 10.7cm solar radio flux，we can get high and low solar active year as follows: HS: 1958, 59, 78, 79, LS: 1962, 63, 64, 74, 80, 81, 88, 89, 75, 76, 84, 85, 90, 91, 2001 86, 95, 96 The Expression of Solar Activity
