Those lines are isobars. They indicate the line at which air is at that certain air pressure.
There are several different lines on a weather map. Lines with triangles leading out from them are referred to as cold fronts, while lines with semi-circles leading out from them are warm fronts. There are also lines on a weather map that are called isobars. They connect areas of equal barometric pressure.

Isobars
it is helpful to use different types of weather map because different weather map could help you, like if a map has a part that you need and the other map does not.

Isopleths typically found on weather maps include isobars (lines of equal pressure), isotherms (lines of equal temperature), and isohyets (lines of equal precipitation). These lines help show patterns and variations in weather conditions across a region.
Isopleths are the lines on a weather map that connect places with the same temperature.
An isobar map is a type of weather map that shows lines connecting points of equal atmospheric pressure. Isobars are used to depict areas of high and low pressure on the map, which helps meteorologists analyze and predict weather patterns.
Those lines are "isobars."
The first weather map was drawn by Sir Francis Galton in 1861. His weather map showed isobars, lines of equal pressure, which revolutionized the understanding of weather patterns.
Isobars are the lines on a weather map that connect points of equal air pressure. These isobars help meteorologists analyze and forecast weather patterns by identifying areas of high and low pressure.
