我国东部沿海一带,除了在主汛期易受温带气旋或热带气旋影响外,非汛期也易遭遇寒潮型风暴潮袭击。对于由强冷空气南下形成的风暴潮影响,有时人们的防御意识较弱,但实际情况表明,不少寒潮的势力强,造成的堤防损失、海损事故相当突出。追究其主要原因:寒潮具有突发性的特点,自起风到增强,往往间隔时间较短,有时来势凶猛,破坏力大。由于前期预报准确度较难掌握,因而预防困难增大。 In addition to being susceptible to either temperate cyclones or tropical cyclones during the main flood season, the coastal areas along the eastern coast of China are also vulnerable to the cold surge storm surge in the non-flood season. For the storm surge caused by strong cold air southward, people are sometimes less aware of their defense. However, the actual situation shows that many cold spells are strong and cause dike losses and sea damage accidents are quite prominent. Investigate its main reasons: cold surge has the characteristics of sudden, since the wind to enhance, often shorter intervals, sometimes ferocious, destructive. As the accuracy of early prediction is more difficult to grasp, so prevention difficulties increase.
