南印度洋风场时空特征分析 总被引：1，自引：2，他引：1
本文根据1950～1995年共46a的南印度洋船舶气象报资料,按1°×1°和5°×5°网格统计的海面风进行分析研究。通过分析每月各要素的等值线分布图,得出南印度洋风场季节变化不如北半球各大洋显著,但仍有较明显的季节变化,只是季节性差异较小,冬季比夏季风强盛,相应的平均风速、6级和8级以上大风频率也较大;全年风场基本相似,10°S以北为季风气候区,而其它海域信风区常年盛行东南风,40°S以南盛行偏西风。本文为船舶远洋交通运输、远洋出访和科学试验等活动,提供了较为详细的风场资料及变化规律。 相似文献

1 IntroductionThe South Indian Ocean is the only way which must be passed in marine traffic among Africa, Asia and Oceania. With the development of the international traffic, it becomes more and more frequent to navigate over the South Indian Ocean. More and more hydrometeorological safeguards especially the safeguards of important cruise lines are required. However, data for the region in China is absent except the Indian Ocean Climate Atlas (1973)[1] which has short fixed number of… 相似文献
