在西非，季节内的时间尺度至关重要，因为那里的资源高度依赖降雨。已经确定了三种主要的变异模式，两种模式的平均周期为 15 天，另一种模式的平均周期为 40 天左右。这些模式具有区域范围，可以强烈影响降水和对流活动。它们主要受大气动力学和地表相互作用的控制。它们还可以调节非洲夏季季风爆发的特定阶段。为了提高其可预测性，有必要更好地了解控制这一规模的机制。版权所有 © 2010 英国皇家气象学会
The intraseasonal time scale is critical in West Africa where resources are highly rainfall dependent. Three main modes of variability have been identified, two with a mean periodicity of 15 days and one with a mean periodicity around 40 days. These modes have a regional scale and can strongly influence precipitation and convective activity. They are mainly controlled by atmospheric dynamics and land–surface interactions. They can also modulate the very specific phase of the African summer monsoon onset. A better knowledge of the mechanisms controlling this scale is necessary to improve its predictability.
