等压线和等压面由于高度抽象,对于中学生而言,其判读会存在一定的困难。由于等压面有不同的表示方式,而气象部门对等压面又有很多专业的规定,这更增添了判读的复杂性。笔者认为,要正确判读等压线图,下列四个方面的问题应引起重视。一、等压线和等压面的甄别等压面是空间上气压相同的点连成的面。而等压线是指在一个水平面上,气压相等的点连成的线。
Because of the high degree of abstraction of isobars and isobars, there are some difficulties for middle school students in their interpretation. Because the isobaric surfaces have different representations and the meteorological department has many more specialized provisions on the equal pressure surface, this adds more complexity to interpretation. The author believes that the correct interpretation of isobaric charts, the following four aspects of the problem should be paid attention. First, the iso-pressure line and equal pressure surface screening Equal pressure surface is the same point in space pressure into the surface. The isobaric line is in a horizontal plane, the same pressure point into the line.
