【摘要】 本文利用１９７９～１９８１年春、秋季黄渤海气象联防的大风资料，对海上为８ｍ／ｓ以上强风及大风天气情况下，渤海海上风与沿岸实测风进行日变化、季节变化、日较差分析以及多点间的对比分析。通过分析可以看出海上风、沿岸风及其比值都具有明显的日变化和季节变化，而且其比值与日较差随季节和风向而变化。该结果对于渤海海面风场客观分析具有重要的应用价值。更多还原

【Abstract】 The observations of sea and coastal wind in the strong wind weather conditions in spring and autumn of Bohai(1979～1981) are analyzed.It can be found that sea wind,coastal wind and their ratio are with obvious daily and seasonal variation.Moreover,the ratio and the daily range of the sea and coastal wind vary with the season and the wind direction.Analysis also indicates that thermal,dynamical and topographical influence and the elevation of the observational stations are the main causes for the difference of the sea,island and coastal wind.The results are very valuable for objective analysis on the wind field of Bohai.更多还原
