环流指数

In the experiment focused on decadal changes, GCMs reproduce the observed NAO shifts in recent decades by imposing strengthening trends on stratospheric wind. The cooling belt extending from North Africa to subtropical Eurasia is simulated accompanying the strengthening of NAO. East end of this cooling belt reaches the eastern flank of Tibetan Plateau.

在强调年代际变化的实验中，通过在平流层中强迫出水平风场的线性增强趋势，大气环流模式可以模拟出近几十年间冬季NAO指数的年代际上升；伴随着NAO正位相的增强，模式可以再现北非至副热带欧亚大陆的冷却带，且其东端可以到达青藏高原下游地区。

Based on the Arctic 1°×1° sea-ice area index,500hPa heights,sea surface pressure and the China 160 Stations temperature data,the relationship between the interdecadal variation of sea-ice in Davis Strait and the atmospheric circulation is discussed by statistical analysis methods.

利用北极1°×1°海冰面积指数、海平面气压、500hPa高度场和中国160站气温等资料，运用统计分析方法讨论了戴维斯海峡海冰的长期变化趋势、年代际变化及其与大气环流的关系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
