INFLUENCE IF ATMOSPHERIC MOISTURE TRANSPORT ON ICE COVERAGE IN POLAR REGIONS

Change in Earth's polar ice sheets is potentially a major source of sea level variability, dramatically affecting global water cycle. One important component in the polar region water balance is the atmospheric moisture transported from lower latitude, which is traditionally estimated from rawi...
