混合层高度变化趋势及其代表值的探讨

Discussion on the Trend and Representation of Mixing-layer Depth

利用长江下游某地的气象资料探讨了混合层高度的时刻、月份和季节变化规律,并得出结论:用2:00、8:00、14:00、20:00时刻的气象资料对年日平均有很好的代表性,用4、7、10、12月份对春、夏、秋、冬也有较好的代表性。

The hourly, monthly and seasonal average depth trend of mixed-layer is discussed in this paper. Furthermore, the conclusion is drawn that the meteorologic data of 4 hours, that is 2, 8, 14, 20 o'clock , can greatly represent the 24 hours on a day and the mixed-layer depth of April, July, October and December can respectively signify Spring, Summer, Autumn and Winter to the great extent.
