论文摘要
地球的年度温度周期紧随太阳通量的年度周期。在温带纬度上，驾驶和响应周期都通过强大的年度正弦成分和非散热的半年度成分进行了很好的描述。对美国历史气象站记录的新分析确定了持续的年度和半年度变化，高精度。历史年度温度范围与先前的研究一致。基于半年度太阳能驾驶，半年度温度周期比预期的要强得多。相反，这些周期与两个年度周期的乘法效应一致。我们的方法为气候对太阳能驾驶的非线性响应提供了一个定量窗口，这在测试气候模型中具有潜在的价值。
The annual temperature cycle of the earth closely follows the annual cycle of solar flux. At temperate latitudes, both driving and response cycles are well described by a strong annual sinusoidal component and a non-vanishing semiannual component. A new analysis of historical weather station records in the United States determines persistent annual and semiannual variation with high precision. Historical annual temperature ranges are consistent with prior studies. Semiannual temperature cycles were much stronger than expected based on the semiannual solar driving. Instead, these cycles were consistent with multiplicative effects of two annual cycles. Our methods provide a quantitative window into the climate's nonlinear response to solar driving, which is of potential value in testing climate models.
