摘　　要：多年的天气实践指出:苏北地区的冰雹等强对流天气,通常发生在海州湾沿岸温度梯度较大的暖陆一侧。本文应用一个二维动力学模式对海陆温差引起的环流进行了模拟,结果表明:强对流天气能够在海风锋环流的上升支气流中得到进一步发展。It is noted for manv years that heavy convective prec ip itat ion (hail) of Nor-thern Jiangsu usuallv take place over warm-land places nearbv Haizhou Bay where the temperature gradient is larger than that over otherwheres. The circulation caused by sea-land temperature difference has been simulated by using a two-dimensional dynamical model, the result shows that the heavy convective precipitation can further be developed in upward current regions of sea breeze front circulat ion.
