本文首先利用实测资料建立了长江流域和华北地区雨季降水与850 hPa纬向风场之间的联系，然后对IPCC第四次评估报告（AR 4）模式对这种联系和降水量的模拟进行了评价。结果表明，长江流域6 - 7月降水量与风场梯度、华北地区7 - 8月降水量与风场梯度存在显著的正相关关系。这些协会是强大的，在每日，每月和年际尺度。虽然许多模式被发现能够模拟的协会，降水量仍然是相当不足的，与观测相比，从而提出了低层风模拟的重要性的问题。
AbstractThis study first used measurements to establish the association between the rainy season precipitation in the Yangtze River valley (YRV) and north China (NC) and the 850-hPa meridional wind, and then evaluated the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) models’ simulations of both the associations and precipitation amount. It is shown that there exists a statistically significant positive correlation in the June–July precipitation and wind gradient over the YRV, and in the July–August precipitation and wind over NC. These associations are robust at daily, monthly, and interannual scales. Although many models are found to be capable of simulating the associations, the precipitation amount is still quite inadequate when compared with observations, thus raising the issue of the importance of lower-level wind simulations.
