北半球副热带高压强度对太阳活动的响应
RESPONSE OF SOLAR ACTIVITY IN THE INTENSITY OF THE SUBTROPICAL HIGHS IN THE NORTHERN HEMISPHERE
【摘要】 利用近38年(1954—1991)逐月500hPa高度数据确定的北半球副各到高强度资料统计了和太阳黑子数以及10.7cm射电通量的相关性,在考虑序列自相关性基础上进行了严格的检验,进一步肯定了一系列高相关联系;其次,利用非整数(年)波方法算出各副高强度在太阳活动主周期(10.9年)处有显著的响应.对照卫星对太阳“常数”的最新探测结果表明,北半球(尤其是东太平洋)副高强度的确能对太阳活动强度作出灵敏的正相关响应.
【Abstract】 Using the intensity data of northern subtropical high measured by monthly 500 hPa height charts for the recent 38 years (1954- 1991), we calculate. their correlations with the monthly sunspot number and monthly solar radio flux at 10. 7 cm wave length,respectively. Through strictly testing, we further confirm a series of high correlations. Next,using a method called the non-integer(year) wave, we find significant response of each subtropical higk’s intensity to solar activity at its main period of 10.9 year length. Special attention is ppaid on that of the esat Pacific high, the ppossible mechanism of such sensible response is also analysed
