摘要：We have investigated the spatial patterns of trends in summer precipitation amount,
intensity, and heavy precipitation for South Korea between 1973 and 2005. All
stations show increasing trends in precipitation amount during the summer months,
with the highest percentage of significant increase in June precipitation for the
northern and central western part of South Korea. There is a significant increase in
August precipitation for stations in the southeastern part of South Korea. Only
a few stations exhibited significant upward trends in September precipitation.
There is a weak to moderate spatial autocorrelation with the highest Moran's
I value in June precipitation amount and August precipitation intensity. The number of days
with daily precipitation exceeding 50 and 30 mm during the summer has increased at all
stations. Observed trends are likely to be associated with changes in large-scale
atmospheric circulation, sea surface temperature anomalies, and orography, but detailed
causes of these trends need further investigation.
