东北信风

绕过菲尼斯特雷角之后，这些船开始在东北信风的吹送下破浪前行。

After rounding Cape Finisterre the boats ride the north-easterly trades .

随着气候的波动，该切变带发生了短周期的南北向漂变，造成西风与东北信风交替现象。

The short period NS drifts of the divergent latitude in response to the climatic fluctuations are responsible for the alternation of westerly winds and northeasterly trade winds .

明清以来，中国渔民每年乘东北信风南下至南沙群岛海域从事渔业生产活动，直至次年乘西南信风返回大陆。

Starting from the Ming and Qing Dynasties , Chinese fishermen sailed southward on the northeasterly monsoon to Nansha Qundao and relevant waters for fishery production activities and returned on the southwesterly monsoon to the mainland the following year .

结果表明：低纬积云对流作用加强了东北季风和东北信风，但阻滞了热带辐合带进一步南移。

Numerical experiments show that : in low latitude , the cumulus convection effects can intensify the north-east monsoon wind and north-east trade wind , keep ITCZ from transferring southward further .
