Hydrological Cycle

Hydrological cycle and climate zone shift (수문 순환과 기후대 이동)

Hydrological cycle plays an important role in heat and energy exchanges between the atmosphere, the land, and the ocean, driving atmospheric and oceanic circulations and thereby determining global and regional climate zones. Therefore, understanding changes in the hydrological cycle under global warming is imperative to understand past and future changes in climate zone and seasonal cycle. In particular one needs to understand anthropogenic and natural mechanisms for changes in atmospheric and oceanic circulations. Recent challenging issues include the poleward expansion of Hadley cell, the impact of volcanic eruptions in the global and regional hydrological cycle, and changes in the amplitude and shape of the seasonal cycle, which are actively being studied by analyzing various observations and climate model experiments.
