空间模 meaning in Chinese

spatial mode

From ocm layer to 30cm layer , the first rotated loading vector field in every layer reflects the anomalous soil humidity pattern in huai river basin , we call the pattern structure as " huai river pattern " . while from 30cm layer to 50cm layer , the second rotated loading vector field in every layer is also quite similar to " huai river pattern " . in the summer and autumn the " huai river pattern " is still remarkable but the feature is less prominent than that in the springtime
发现春季以30cm为界， 30cm以上各层土壤湿度异常的第一旋转空间模态十分相似，其大值中心主要位于淮河流域，而30cm以下( 30 - 50cm )各层的第二旋转空间模态与之亦十分类似，因此称该模态为“淮河型” ，而夏季和秋季虽然该模态也很显著但特征不如春季突出。
Therefore , the physical mechanics of ao also presents seasonal variability . while thermal forcing plays an important role in the process of summertime ao formation and maintenance , wintertime ao is subject to the dynamic process . this is probably the radical cause of the seasonal discrepancy of ao
因此热力强迫作用在夏季北极涛动的形成和维持机制中占重要地位，而冬季北极涛动的维持机制主要是动力作用的结果，热力作用只在对流层低层起作用，这也是二者空间模态和结构差异的主要原因。
