该算法可精确地绘制出等压线。

This algorithm can draw isobar accurately.

在气象图上气压差用等压线表示。

Pressure differences are indicated on weather maps by isobars.

气压梯度与天气图上等压线的间隔大小成反比。

The atmosphere pressure gradient is an inverse measure of the spacing of the isobars on a weather map.

具有大致同心的等压线的低压区在技术上称为气旋。

A region of low pressure with roughly concentric isobars is known technically as a cyclone.
