摘　　要：利用1950～1995年我国近邻海域的海平面气压资料,对我国近邻海域海平面气压场及气压梯度进行分析。分析结果表明:我国近邻海域海平面气压及气压梯度存在明显的季节变化,冬季气压场纬向变化明显;夏季呈经向分布;春、秋季气压场变化较快,是气压场经向、纬向分布的转型期。Based on the data of sea-level pressure from 1950 to 1995 ,the pressure field and gradient in our offshore area are analyzed. The results show that the season variety of pressure field and gradient is distinct. The pressure field has an obvious zonal variation in winter, while it is meridional distribution in summer. In spring and autumn, the pressure field changes quickly. So it is the transformation period between meridional and zonal distribution.
