严重的冰冻对佛罗里达中部的柑橘种植者来说是一个严重的问题。为了研究间歇性冰冻的可能气候原因，本文研究了几种大气环流模式对佛罗里达冬季气温的影响。太平洋/北美模式被证明是特别有影响力的，北大西洋涛动也是显着的，而南方涛动没有显示出直接的影响。佛罗里达冬季气温自1947年以来的下降趋势可以用前两种环流型的波动来解释。对这些环流模式的频率或位置可能发生的变化进行的气候模式研究可能表明，与气候变化有关的冰冻风险可能发生变化。
Abstract Severe freezes are a serious problem for the citrus growers of central Florida. To investigate possible climatic causes of intermittent freezes, this paper examines the influence of several atmospheric circulation patterns on winter temperatures in Florida. The Pacific/North American pattern is shown to be particularly influential and the North Atlantic Oscillation also to be significant, while the Southern Oscillation does not show a direct effect. A decreasing trend in Florida winter temperatures since 1947 can be explained by fluctuations in the former two circulation patterns. Climate model studies to investigate possible changes in the frequency or location of these circulation patterns could suggest potential changes in the freeze risk associated with climatic change.
