Investigation of factors influencing the impact of inter-annual climate variability and extreme weather events on the hydrological cycle in the Panama Canal basin

In this study, we first collect hydrometeorological observation data including hydrometeorological observations and historical meteorological radars for highly accurate basin rainfall estimation in the Panama Canal basin, develop gridded precipitation data, and develop regionally detailed (downscaling) data from reanalysis using a regional climate model. By integrating them, we will construct a three-dimensional hydro-meteorological dataset with high spatio-temporal resolution.

In the Panama Canal, which is the most important point in the world's shipping supply chain, the decline in water levels due to drought has become an international issue in recent years, and future changes in precipitation due to global warming are a major concern. On the other hand, in the Panama Canal basin, changes in the water cycle in the basin are not fully understood. Based on the developed dataset, we will investigate the causes of changes in the water cycle in the Panama Canal basin by: 1. Elucidating the causes of past floods and droughts using climate indicators; 2. Elucidating the causes of water cycle changes, including human activities; and 3. Elucidating the cause of flood induced heavy rainfall. The weather and climate analysis of the event will be clarified from three perspectives.
