以前对陆-气相互作用（土壤湿度对降水的影响）的估计受到缺乏观测数据和计算估计依赖模型的限制。为了克服第二个限制，十几个气候模拟小组最近进行了同样的高度受控的数值实验，作为协调比较项目的一部分。这使得在地球上的地区，降水受土壤水分异常在北方半球夏季多模式估计。这种估计的潜在贝内可能包括改进季节性降雨预报。
Previous estimates of land-atmosphere interaction (the impact of soil moisture on precipitation) have been limited by a lack of observational data and by the model dependence of computational estimates. To counter the second limitation, a dozen climate-modeling groups have recently performed the same highly controlled numerical experiment as part of a coordinated comparison project. This allows a multimodel estimation of the regions on Earth where precipitation is affected by soil moisture anomalies during Northern Hemisphere summer. Potential bene its of this estimation may include improved seasonal rainfall forecasts.
