Answer:
The large red L's on a surface map represent centers of low pressure, also known as mid-latitude cyclonic storms.
Step-by-step explanation:
These storms are characterized by rotating winds that move counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The low pressure at the center of the storm causes air to rise, leading to cloud formation and precipitation. Mid-latitude cyclonic storms are also known as extratropical cyclones and are common in the middle latitudes (around 30-60 degrees) of both hemispheres.
