Types of Precipitation Patterns
There are several types of precipitation patterns observed in Jeju Island during May, each with its unique characteristics and causes. Here are three of the most notable types:

Central Highlands: The central highlands experience a unique rainfall pattern, with rainfall events typically centered on the highland areas. This region receives more rainfall than the western and eastern coastal areas, due to its proximity to the central axis of the Asian monsoon system.
The rainfall patterns in Jeju Island during May are influenced by various factors, including the prevailing wind direction, the trajectory of incoming weather systems, and the island’s unique geography. This complex interplay of factors results in diverse rainfall patterns across different regions, with some areas receiving more precipitation than others.
