What do you think of subtropical high?

Subtropical high can be seen from the weather map of 500-700 hectopascals. Generally, the weather map of 500 hectopascals is used more. The characteristic line of subtropical high on the 500 HPA weather map is 588; Characteristic line of subtropical high on 700hPa weather map: 316; Characteristic line of subtropical high on 850hPa weather map: 156.

500 hectopascal weather map

Area index: calculate the number of grid points larger than 588 potential meters on the 500 hectopascal map, indicating the common area index of the western Pacific subtropical high.

Average ridge position: the average latitude of the subtropical high ridge line in the range of1/kloc-0 ~150 e.

Location of northern boundary: average latitude of line 588 north of subtropical high.

West extension ridge point: the longitude of the westernmost point on the subtropical high body in the western Pacific Ocean (the range enclosed by 588 potential meters isoline).
