“经线的”常见英文表达是 “meridional”(尤用于地理学、气象学等专业领域,描述与经线相关的特性),也可用 “of the meridian(s)” 来更直白地表述“属于经线的”。
例如:
The meridional wind refers to the wind component along the meridian.(经线风指的是沿经线方向的风分量 。)
The characteristics of the climate in this region are closely related to the factors of the meridians.(这个地区的气候特征与经线的相关因素密切相关 。 )
We need to analyze the data collected along the lines of the meridians.(我们需要分析沿着经线收集的数据。)
