地球自转速率变化对东亚夏季环流型的可能影响

POSSIBLE INFLUENCE OF VARIATION IN EARTH′S ROTATION RATE ON EAST ASIAN CIRCULATION PATTERNS IN SUMMER

研究了地球自转速率变化对大气运动影响的纬度效应，讨论了其与副热带高压系统尺度特征影响程度的相关关系，分析了其对中国旱涝时空分布的影响，模拟了其纬向分量偏差场、西风廓线“形变”、西太平洋“附加环流型”

This paper concerns the latitude effect on atmospheric motion produced by variation in earth′s rotation rate, with the correlativity between the scale characteristics of the subtropical high system and the impact degree documented, the influence on space/time patterns of summertime flood/drought in China investigated, and the u component difference field, deformation of westerly profile and additional circulation pattern over the western Pacific.
