We simulate twenty, perpetual Januaries each under solar minimum and maximum conditions using the Freie Universität Berlin Climate Middle Atmosphere Model with interactive chemistry (FUB CMAM CHEM), including the 27-day solar rotational cycle. Cross-correlation functions (r) of tropical ozone and ultraviolet (UV) suggest peak values of +0.5 to +0.6 (with % changes in ozone of 0.4–0.6%) in the middle atmosphere. Temperature in the middle atmosphere varies with UV by up to 0.5 K, which appears to be mainly dynamical in origin. We calculate a signal associated with the rotational cycle in the troposphere, although this requires further investigations.  相似文献
