They are isobars: Places of equal air pressure. Air pressure then tells you the speed and properties of wind. The closer together the isobars, the stronger the winds. You can tell what direction the winds are by looking at the high and low pressure cells, in the Southern Hemisphere wind travels anti clockwise around high pressure systems, and clockwise around low pressure systems. If the wind is coming onshore, the wind will be moist. If it is coming over dry land it will be dry, and probably hot, for example if your on the east coast of Australia and the wind is a westerly (traveling from west to east across the hot dry desert) it can be assumed that this wind will bring hot and dry conditions to those areas along the east coast.
Curving lines on a weather map connect locations with the same air pressure
Usually those are isobars - lines of equal barometric pressure.
a curved line on a weather map indicates areas of equal air pressures
isobars lines of equal pressure
Meteorology. a line drawn on a weather map or chart that connects points at which the barometric pressure is the same.(D)to connect points of equal air pressure on a weather map

Such a map is commonly known as a nautical chart.

Isotherms on a weather chart or map, links places of a constant or equal Temperature.
A clinograph otherwise called a weather graph/map It is two graphs constucted on one x and y axis with temprature (a line graph) drawn at the top of the graph and the rainfall (bar graph)
An agonic line is a line on a chart or map showing points of zero magnetic declination.
