What are the most common weather map projections?

The creation of weather maps involves projecting Earth’s spherical surface onto a flat map. This process always distorts the map to some degree, so mapmakers must choose projection methods carefully depending on where the map needs to be the most accurate. Here are three of the most common projections:

  • Cylindrical projections depict the globe’s surface as if wrapped around a cylinder. This results in equal spacing of longitude lines but can cause distortion as one moves away from the equator, making them suitable for showing weather patterns over broad regions.
  • Conic projections project the Earth’s surface onto an imaginary cone positioned over the North or South Pole. These projections are often used for mapping mid-latitude areas. They minimize distortion in these regions but can cause issues near the poles.
  • Plane projections, also known as azimuthal projections, project the Earth’s surface onto a flat plane from a single point. These are particularly useful for depicting polar regions and maintaining accurate directions, but they exhibit distortion when portraying larger areas.
