What abbreviation stands for "below" in weather reporting?

This term is commonly used in aviation and meteorological communications to indicate that a specific value, such as cloud height or temperature, is situated beneath a certain reference point. For instance, if a report states that the cloud base is at 2000 feet above ground level and the weather conditions are described as "below," it signifies that certain phenomena or conditions are occurring at altitudes lower than that specified height.

In the context of aviation operations, using standardized abbreviations like BLW helps ensure clarity and consistency in communication between pilots and air traffic controllers, reducing the chances of misunderstanding critical information.
