The Vietnamese word "bắc vĩ tuyến" translates to "north parallel" in English. It refers to a line of latitude that is situated to the north of the equator. In geography, these lines are used to measure how far north or south a location is from the equator, which is at 0 degrees latitude.
In more advanced discussions, "bắc vĩ tuyến" can be used in contexts involving climate studies, ecology, or even politics. For example: - "Khi nghiên cứu khí hậu, các nhà khoa học thường xem xét ảnh hưởng của vị trí địa lý, như bắc vĩ tuyến, đến điều kiện thời tiết." This means, "When studying climate, scientists often consider the impact of geographic location, such as the north parallel, on weather conditions."
While "bắc vĩ tuyến" specifically refers to north latitude, it does not have other meanings in different contexts. It strictly pertains to geography.
