Analysis of Linear Precipitation System in Kyushu Region Using Som and Diagnostic Model

Key Points

• The research aims to analyze the relationship between meteorological patterns and linear precipitation systems in the Kyushu region.
• Utilized self-organizing maps (SOM) and analyzed precipitation data.
• Identified relationships between meteorological patterns and linear precipitation occurrences.
• Focused on the specific groups of weather patterns contributing to precipitation in distinct areas of Kyushu.
• Found a higher incidence of linear precipitation associated with moist air influx from the East China Sea.
• Identified three distinct meteorological patterns linked to increased linear precipitation in southern, western, and northern Kyushu.
• Confirmed prediction models indicated conditions favorable for linear precipitation in southern Kyushu during a specific event.
