- Subtropical High-Pressure Belts: These belts are located around 30 degrees latitude in both the Northern and Southern Hemispheres. They are characterized by relatively weak winds and stable atmospheric conditions.
- Horse Latitudes: The horse latitudes are located between the subtropical high-pressure belts and the trade winds, generally between 30 and 35 degrees latitude. They are known for weak and variable winds, which made sailing challenging for historical sailors.
- Inland Areas: Areas far from large bodies of water, such as continental interiors, often experience weaker winds compared to coastal regions.
- Mountain Valleys: Valleys surrounded by mountains can have weak winds due to the sheltering effect of the mountains, which block strong winds.
- Polar Regions: The polar regions, especially the polar night regions during the winter, can experience weak winds due to the stable and cold atmospheric conditions.
